Re: Look @ the job DPMS did on my .30 remington ar

Im sorry but I dont believe thats what its supposed to look like, cant say that I have looked at a DPMS LR308 barrel extensions in a few years but I would have remembered seeing something that ugly. They are plenty of DPMS LR308 owners on here who can chime in with pics of their feedramps for you.

Re: Look @ the job DPMS did on my .30 remington ar

I am confident that DPMS will make it right in the end, and I also skeptical that they did that in the first place.

Do you think they outsourced it or are you trying to infer that I did this and Im trying to put the blame on DPMS and bash them, I kind of get the feeling by your "--Just saying" comment you are trying to say I did this. Just to put and end to your skepticism, you see all those 0's on the invoice? That means no charge, the warranty covered their work they preformed. If I damaged that rifle like that by modifying it and sent it in to have the dust cover repaired (because that's why it was sent in initially) and they saw the feed ramp, barrel extension and upper receiver in that condition, they would have voided the warranty.

How many times do we have to go through this. This is NOT an LR-308. It is an ar-15 chambered in ".30 remington AR", which is fed single stack in a regular .223 magazine much like .458 socom and other ar-sized bigger calibers. The feedramp IS supposed to be clocked, it's the dremel work that is the problem, since it's not only shitty, but irrelevant to the problem he sent it back for in the first place.

Some of you need to work on reading comprehension.

Swagger, good luck... hope they get it right this time around.

Re: Look @ the job DPMS did on my .30 remington ar

Yeah man, Its hard for me to believe they did this also - hence the reason for this thread - I was in shock when I discovered what they had done. When I called and spoke to customer service, they told me they have pallets of rifles that are waiting to be repaired and it is going to take a while to be corrected. I guess Im not the only one with issues when it comes to DPMS products. It really makes me want to run to the range with my (2) R-25's and my LR-308B to test them thoroughly before the warranties run out. Anyway, the rifle is on the big brown truck headed out to them as we speak @ their expense. (At least they gave me a pre-paid shipping label)

Re: Look @ the job DPMS did on my .30 remington ar

No hard feelings brother. It's just that I don't have any history with you, but I have enough experience with DPMS to have a fair amount of trust in them...so far.
Was going to ask if you had two of these. Guess so.

 

[Bob L Swagger]

Re: Look @ the job DPMS did on my .30 remington ar

I only have one R-15 .30 remingotn AR. My father has one also, his too is at DPMS for repair. I have 2 R-25's in .308 and my father has one, one of mine has not been shot yet, and the other has only been shot like 20 times. My LR-308B has not been shot yet either, I think its time to test them all out. No hard feelings, I just want to make the brothers and sisters of the hide aware of the wrong doings of the manufacturers of our favorite toys.

How much evidence of repairs from DPMS do you look at a day? Cause at the store here we have sent back probably 4 out of 10 DPMS rifles for obvious problems right out of the box. DPMS is slipping. They used to be a good company to go to for 308 platforms and other oddballs but I will stick with others now. No way should a customer have to send in the exact same rifle 3-4 times to get something like that fixed. If they couldn't get to the bottom of the issue they should have outsourced to a gunsmith that is well rounded in these situations. If its covered under warranty and you need a repair, by all means send it in. But if it comes back to you still not right, request that DPMS pay for a qualified gunsmith to look at it.

Fool me once, shame on you.
Fool me twice, shame on me.

I think the service they gave you was not tolerable. It looks like someone took a Dremel and tried to make a feed ramp but failed miserably. At least they have you running now. If it happens again... call a independent smith and ask him what he would charge to look it over and give a quote. Send that quote to DPMS and tell them they need to do what is right by you, the customer.

Good luck with it

Re: Look @ the job DPMS did on my .30 remington ar

My experiences,

Rifle #1
24” LR308 – this was one of the first 1,000 rifles built, so we are talking many years ago. Rifle had constant FTF / FTE problems not matter what ammo was used. Sent the rifle back to DPMS, they replaced the original junk plastic mags with the new metal ones, and reworked the chamber and feed ramps. Many years later, the rifle is running flawlessly, will hold 1 MOA or better, zero complaints.

Rifle #2
16” AP4 in 308 - this was about 4 years ago. No problems out of the box, functioned well, good accuracy for a carbine, no problems or complaints.

Rifle #3
18” SASS in 308 - this was about 4 years ago. No problems out of the box, functioned well, 1 MOA or better, no problems or complaints.

Rifle #4
24” LR260 - this was about 3 years ago. No problems out of the box, functioned well, 1 MOA, no problems or complaints.

Rifle #5
20” “Custom” 260 - this was about 2 years ago. Major problem out of the box, functioned well, but would not hold better than 2-3 MOA. Gunsmith checked barrel with scope, and it looked like it was made in someone’s garage, complete junk. Sent it back to DPMS with full documentation of problem. Long story short, it took many phone calls and emails, but I finally got it back almost 4 months later. New barrel was better than the original, but was not up to par with other rifles, would hold 1-1.5 MOA.


My take,
When the company was small and Randy Luth was in the trenches, things were good. When Cerberus bought the company, the buying madness kicked in as Obama was coming in, production went through the roof, and Randy Luth stepped out, things went in the toilet.

Today, you take your chances, you may get a great rifle, you may get a piece of junk.

I do have to say that from what I have seen in the past, if you get a piece of junk DPMS will make it right. In this case, that obviously did not happen, and they should make it right!

Hopefully as the buying & production madness dies down, DPMS can get back on track producing a good product out of the gate.

Best of Luck,
M Richardson

Re: Look @ the job DPMS did on my .30 remington ar

There might be some truth in the theory that changes in management at DPMS might be causing some problems. I think the jury is still out on that though.

My recent history with DPMS: since the elections of 08, I have bought three of their rifles complete, have bought one complete upper from them and built the lower from DPMS parts, and have built three rifles primarily from DPMS parts.

Not a single issue with any one of them to date. I still own all but one, and have thousands of rounds through them.

Re: Look @ the job DPMS did on my .30 remington ar

BLS:
My intent is not to offend the many happy DPMS owners who I think defied the odds and have units they are satisfied with. However I will challange the fact that DPMS did quality work early on. It is my experience from BNIB units that would not chamber because of headspace issues, multiple units that jammed and really gross cosmetic blems and of course accuracy issues. I spoke with Randy several times and the repair department had me on speed dial till I just got tired of it. There people were polite and focused on the repair. I will say they stood behind there products even it took muliple trips to fix. I hoped they had imnproved but have no intention of finding out by personel experience when you have places like GAP, CLE, AS, WOA and others that get it right the first time.

 

[maggitas]

Re: Look @ the job DPMS did on my .30 remington ar

Bob,

I feel your pain. If I were in your shoes I would call DPMS and talk to a supervisor and make certain that he addresses your concerns. As others have stated, I see no reason for them to actually mill the upper reciever. I can see a newbie not milling the feed ramps to proper specs, but for a gunmaker to allow a product to go out in this condition is neglegent at best and could concievably harm someone. As stated I would try to resolve this by keeping Mark's name on file, but if this turns into a case of you returning the firearm numerous times I would weigh the options of either cutting my losses, Having another gunsmith do the work, or considering legal action.

Regards,

Johnny

Oh really? I assume you must have verified this using a quality GO guage, or at a minimum you have experienced problems with factory ammunition chambering. If so, you have not said so.

Most factory ammo is sized to be just under the SAAMI minimum dimension (like .002-.003"). If your rifle's got a headspace problem (being too short), it is not likely to chamber flawlessly with factory ammo.

You are attempting to use an instrument to do something that it is not designed for. It is not designed to give absolute measurements. It is designed to give comparative measurements (comparing one piece of brass to another, for example). The fact that others have chimed in with vastly different measurements than you have for similar loads should tell you something.

Is it possible that your brass is coming out of the chamber after firing slightly smaller in 'headspace' dimension than when it went in? -- hell yes. Is it something to be concerned about? -- probably not. You say yourself that you are letting the action 'slam home'. What do you think might happen to the brass when you slam it forward into the chamber? There are other reasons the brass might come out a slightly smaller dimension as well. Damn, you are only talking about a couple of thousandths of an inch.

Pressure signs at 2300 fps? OK, what kind of pressure signs? ... and what powder are you using? Could be that what you are seeing is the result of excess port pressure, not chamber pressure. If you are trying to use a slower burning powder, that is probably your problem. ... and you are seeing pressure signs at 2300 fps but decide to go ahead and push it all they way up to 2600 fps anyway? If you don't have a good feel for the signs of excess port pressure vs excess chamber pressure then what you have done is quite stupid.

Where to start with your OCW discussion? Hmmmm. How about this: do yourself a favor and run any external ballistics program to see what the theoretical change in drop at 200 yards is between muzzle velocities of 2250 and 2600 for a 168 gr SMK (I assume that was what you were shooting the test with). Depending on the program you use and the values you put into it, you are going to see something on the order of a 4" change at 200 yards...not 12". Having all those rounds impact within 6 inches of each other is not a big deal, especially when you factor in possible shooter errors and barrel harmonics.

Thanks for the reply. I don't mind getting beaten up as long as I learn something from it. Slap harder if you like.

Factory ammo seems to chamber fine.

Pressure signs are extractor marks.

Using H4895 for this particular situation, but will use RE-15 and AA2520 for later testing...all powders should fall within the pressure curve for this gas system.

Ahhh. You are right H4895 should not be causing you issues. Much faster powder that W760 -- and you are loading it within some load guidelines I have seen. When you say extractor marks, are you saying the rims are bent or are you referring to ejector swipes and/or circular extrusions that protrude slightly on the bottom of the case? In either case, they are typical signs of excess port pressure. Pierced primers sometimes are as well.

With H4895, it would seem that you shouldn't be seeing this unless perhaps your gas port is too large. Or, maybe there is something else going on.

You should conside whether or not this really matters to you. It might, and it might not. Port pressure problems are not dangerous; they just eventually get to the point where they don't allow the autoloader to function correctly. What they will do (even when the the action is still functioning well) is beat up your brass. Swipes -- probably not a bid deal. Bent rims? -- throw that piece of brass away as it is now useless.

I appologize to Bob and all others who have been following for hijacking the thread.

edit. A word of caution: the circular extrusions (from the ejector) can be a sign of excess chamber pressure too, but you will see it in conjuction with very flattened primers in that case.

Re: Look @ the job DPMS did on my .30 remington ar

The rims show the typical extractor marks from the action opening too fast. I'm going to try Tubb's Carrier Weight System which is supposed to slow down the action, especially on heavier bullets.

Ejector marks show up as a round punch on the web of the cartridge, usually over the headstamp or near that area of the case.

Interestingly...I needed to call Hornady for something and got into a conversation with one of the techs. Super nice guy... I think he had some time on his hands so we had a little talk.

Turns out he has an LR-308 from DPMS with very similar problems and he said what you just said: It's port pressure caused by too big a port.

He also slugged his barrel and found the barrel was .001 under minumum .308 barrel dimensions on the lands. He also said that would also cause pressure problems and suggested I slug my barrel just to see.

What kind of slug should I use?

Not to mention, the dust cover still will not stay shut and after firing the rifle today, I noticed there is still a sharp pointy burr on the head stamp of all spent cases.

I find this statement insulting to drunk sailors

I am thinking of only 1, and to call this individual a "craftsman" is giving this person that butchered this, WAY to much credit...

I am thinking the term, "Hack" is better suited.

Oh, OP...sorry you are having to deal with this. I know it's frustrating to say teh least. Good luck, and hopefully it all turns out for best..

Re: Look @ the job DPMS did on my .30 remington ar

I can't believe all the guys who still think this is a LR308.

The 30AR was designed to throw 308 bullets out of an AR15 platform.

And then we got off on a reloading symposium.

And someone wants the OP to print and send all this to DPMS to show "We're watching You!"? WTF

All I can say is HOLY SHIT Bob! And welcome to Remington Country.
Good luck on your endeavor.

Re: Look @ the job DPMS did on my .30 remington ar

Thanks for all your support and input fellas, the rifle is now at DPMS. Im going to call them in a short while and see what the story is.

Re: Look @ the job DPMS did on my .30 remington ar

Keep us informed Bob. I have been down that road with DPMS about a rifle that I purchased from them. I finally got a refund. The last thing that I ever owned that had DPMS name on it was one of their 45 round AR mags that I purchased from Brownells. Thank goodness for Brownells being the great company that they are, the mag was returned because the follower was stuck where the mag was joined together. That piece of S--t mag cost me a 3 gun match. I should have known to not purchase anything that had DPMS on it. I am sure that there are good products and good people at DPMS, but I have had bad luck with them.

Re: Look @ the job DPMS did on my .30 remington ar

THe primary problem with your gun is that it was made by DPMS, and then fucked up some more by DPMS.

For AR15 rifles, please stick to Colt, BCM, LMT, Noveske, Daniel Defense, KAC and Larue. Otherwise, this kind of bullshit happens.

That is really annoying that you would list a set of extra expensive rifles.

Re: Look @ the job DPMS did on my .30 remington ar

Bob,

There is a shop in Lakewood NJ That will sell you a LMT 308 for about $2,200 with the mods to make it legal in NJ. I feel that rifle is the way to go. And once you have it in your hands you will never let it go. My DPMS had to be sent JP enterprise to make the trigger correct. It works and shoots incredible. If you want try it at 600yd cumberland rifleman give me a heads up.

Re: Look @ the job DPMS did on my .30 remington ar

I learned an important (fact?) here. If DPMS has pallets of rifles returning, I'm done, but I was nearly done anyway with mass produced guns anyway.

Re: Look @ the job DPMS did on my .30 remington ar

Well, I called DPMS to see whats going on with my rifle. According to the tracking number from UPS the rifle was delivered to DPMS on Jan 31 at 8:31am . I spoke to Mark I. and he stated it was "entered into the system" on Feb. 4th. According to him "entered into the system" means its being worked on and its on a technicians bench. Lets see... Feb. 4th to Feb. 21st thats 17 DAYS!!! I can't believe it takes a company 17 days to make a rifle right. I get the feeling they are stalling in order to run out the warranty. Im starting to lose my patience.

 

[T2CH]

Re: Look @ the job DPMS did on my .30 remington ar

That sucks. The warranty should be extended on the parts they work on (they probably will not honor that though). Ask them for an extended warranty for your troubles.
Good Luck
