LMT vs. LWRC?

[dmachine]

Can anyone tell me which of these two uppers is "better", and why?
I want a top notch AR-15 upper, my SHTF go-to gun, so to speak. I want it to be gas piston operated, 14.5", railed handgaurd, flip up buis, 1:7 trist med. heavy barrel chrome lined, and a good rugged finish.

The two I like best are LWRC & LMT (CQB MRP) I have always liked the LMT MRP system's quick change barrel system, but I'v also always wondered just how rugged it is. Now they have it in a piston version, makes it even nicer. Both LMT & LWRC have bolt carrier's that help eliminate carrier tilt and both have a self regulating gas system. Can anyone tell me which of these two upper's is better, and why?
I really like the LWRC, but I also really like the ability to change from 5.56 to 6.8spc Both are big $, esp. the LWRC! Which system would you rely on to save your life in any condition?

I'm not sure that one is "better" than the other but I've tagged this also.....I'm curious

Re: LMT vs. LWRC?

go with the proven winner, LWRCI, the M6 series is highly endorsed by Pat Rogers.

personally i own 5 LWRC & LWRCI products, the short stroke piston they use was invented by Paul Leitner-Wise and is copied with variations so as to not violate patent rights, Leitner-Wise Defense has improved on this design that has made his former piston look primitive. for the very best in pistons check this out:

this design is so simple even a Caveman can figure it out, no tools needed to remove the forearm and the piston system for "cleaning??" which is and should be a rare event. i just wish i could show you all how easily this superior upper can be disassembled for what ever reason the owner wishes.

the uppers are available for sale right this moment, mine has nearly 1,000 rnds thru it and NOT one hiccup !! if anyone wants more info just ask me OK ?

Re: LMT vs. LWRC?

I'm a die-hard LWRC guy, in fact I currently own 6 of them. I'm not trying to start any debate, but in my opinion they are the best gas piston rifle on the market. Keep in mind that there are alot of factors when buying a CQB rifle, including piston length, adjustable gas vs. non adjustable, barrel length, plans to suppress, etc. If you want a 14.7" barrel, consider buying a M6A2-S. This rifle will give you a short barrel with true mid-length gas piston.

I can't speak to the LMT, but given the quality of everything else that they make, you probably can't go wrong with one of those either.

You can check out the following forum for more info;

Re: LMT vs. LWRC?

I own two a 12" (unfired) and a 16" piston upper for LMT, and it is amazing. The quality is outstanding, and so far I have not had a single problem through 600-700 shots.

You honestly cannot go wrong either way, but I would buy from LMT.

Piston Pete, are you PLW then? The link you gave is PLW's site I believe and not LWRCI.

Re: LMT vs. LWRC?

Don't forget that LMT is still using the SAAMI chamber and twist specs for their 6.8 MRP barrels which hurts the performance of the round. They also have no intent of selling individual barrel extensions so that you could have your own barrel installed. I don't think they are interested in using the newer 1:11 and 1:12 twists and SPC II and DMR chambers.

LWRC.

Re: LMT vs. LWRC?

LWRC. Not that I know of any problems with LMT, but my truck gun is an LWRC M6A3, 14 incher with a permanently-attached SPR/M4 suppressor mount(sent the mount to LWRC and they did an admirable job of PA-ing it.) It's never stumbled once. I've cleaned it twice since it came in. Workmanship is fantastic - and I'm especially proud of the cold hammer-forged barrel, one-piece carrier, and adjustable gas block. You may not need the adjustable gas block of the A3, but it sure is fun to turn it off and hand-cycle your rifle for quiet, clean operation!

My Pop runs a M6A2 from LWRC and it's boringly reliable as well. They took his M1A away while he was in the Army and replaced it with the M16 - he's hated the black rifle ever since. I couldn't believe it when he expressed interest in the LWRC M6A2 after inspecting it! He bought it and it's his go-to gun for coyotes, etc. now. Fine stuff. I'm planning on getting one of their DMR A3 as soon as possible.

Here's mine when it was spanky new:

Here is an article comparing the LMT piston to the HK416. LINK

ha ha ha, funny guy, i gave the site i want you to go to, everyone already knows LWRCIs web site by now, don't you think ?

lets concentrate on the piston systems and leave personalities out of this OK ??

i have a Colt 6721 upper that i sent to LWRC (Leitner-Wise Rifle Company) around 2001ad for conversion to a piston upper, this was the original design short stroke piston, that Paul Leitner-Wise invented, i have another piston upper made by LWRC (Land Warfare Resources Corporation), that piston system is exactly the same as was first used, then recently i bought an M6A2 from LWRCI (Land Warfare Resources Corporation International) it has the exact same piston design as the other two invented by Paul Leitner-Wise


now then, switch over to Leitner-Wise Defense and look at the new and totally improved piston system, also invented by Paul Leitner-Wise, the ease of removing the rail for access to the piston and it's ease of removable parts and strip it right down to the bare barrel.

psssst.., do not tell anyone, but i have one of his first complete rifles, i have been testing it against the LWRCIs M6A2 which has a 1-7 twist, the Mod. 1 has a 1-9 twist which i like a lot better, at 100 yds i can not tell any difference, with 55, 62, 69 and 77 gr. bullets, maybe a slight edge on 55 grs. from the 1-9 twist (55 grain bullets were designed for the 1-12 twist, i.e. M16) my test is far from over those loads were for TAC powder in various weights of powder, chronographing the loads and recording the results takes a lot of time, i am not even half way with TAC powder, i have BLC-2 and Winchester 748 powder yet to go, three different primers, and the above mentioned 4 bullet weights, this could take a long time.., but fun !!

Re: LMT vs. LWRC?

Thanks everyone!
I didn't know that LWRC had an adj. gas block, is it just on & off or are there setting's for hot ammo, weak ammo and suppressed? (I thought they were self regulating.) I was hoping they had a true mid length gas system also. Two very nice LWRC rifles I saw on Future Weapons were, The PSD 6.8 SPC and a reg. length one that was tough enough to be a SAW but was mag fed. Both were outstanding weapons for their task's.
Where do you buy LWRC upper's? Do you have to buy from them, or is there a better place to buy that can save you some money?

Re: LMT vs. LWRC?

Another small point to consider, somebody chime in if I am wrong, is the fact that the LWRC has a removable rail system and the LMT is a monolithic upper (rail cannot be removed). Don't know if that makes a difference or not but piston AR's are inherently heavier by design than a direct impengment AR. With that said the LWRC (since it is not a monolithic upper) should be slightly lighter than the LMT which is monolithic. Another point for consideration is that a Monolithic rail is a more solid mounting platform for optics and accessories because it is all one piece and is part of the receiver. Anyways, those are probably mute points but just wanted you to be aware of some of the other parts other than the piston systems themselves.

 

[dmachine]

Re: LMT vs. LWRC?

I am aware of the way the monolithic upper work's vs. the std. one with a rail system. I do like the ruggedness of the mono unit, and the fact that you can just pull the piston out of the front of it. However, I'm OK with the std. type with a good rugged rail forarm. I never mount the main optic farther forward than the rail on the reciever anyway, laser's, light's and bipod's, but not the main sight.

Re: LMT vs. LWRC?

FYI,
The adjustable gas system settings are as follows;

Please note that the quote below was cut and pasted from LWRC's forum.

<span style="font-style: italic">From what I understand

N = Normal, normally gassed
S = Suppressed, reduced gas
A = Adverse, over gassed
C = Closed, no gas

Always use N unless suppressed or your gun is so jammed with crud it wont run. You should almost NEVER need A unless the gun is in a frozen desert with no lube and a bazzilion rounds though it without cleaning.

S is used to decrease cyclic rate with a suppressor, N works too but at a higher cyclic rate.

C lets you operate the gun manually with full power ammo. Use if you want to be super quiet when suppressed and not suffer any blow back.</span>

You can purchase uppers and complete rifles from many different vendors. I typically buy from Scottsdale Gun Club because they are one of LWRC's largest vendors and their customer service is second to none. If they do not have what you are looking for in stock, they will order and usually have it within a couple days. Although not typically advertised, if you are looking for their M6A2-S model, they can order this for you as well.
