Reliable AR10 style that's reliable for "plinking"?

I have over the last 25 years of building , repairing and shooting large frame AR's come to the conclusion that if you can't afford a baseline gun like the SP10, then you can't afford a large frame AR.

LMT, JP, Seekins, KAC, HK , (add Geisselle to the list) and a few others are the only ones worth owning. They will work.

I have owned the above in addition to DPMS, S&W, RRA, POF, LWRI, PSA, CMMG, Aero and a few others that were either trashed or sold to some idiot for pennies on the dollar. I have the tools , knowledge and skills to build them from the ground up, but i refuse to use cheap parts, and when I can, try to order all the major components from the same manufacture to ensure compatibility and avoid tolerance stacking issues. I don't even like building large frames anymore. There are just too many places issues can and will creep up and its not worth the time and money to run them down.

Seriously dude, just buy an SP10 and be done with it. If you can't afford that, then save up. Anything less you are really just buying shit you cant trust and most likely will loose a bunch of money when it comes time to dump it for what you should have bought in the first place.

And with all that being said, the large frame AR is almost obsolete today with cartridges like the 6 arc. You get 90% of the performance for half the cost, less weight, less recoil, way easier to shoot and with the small frame, have much more options to build something that will work vs the large frame. Unless you need the downrange energy, its just wasted on steel or paper and arguably humans when you look at a hit causing a casualty either way. A hit with a 6mm is better than a miss with a 6.5 or .30 cal bullet.

It looks like your moving towards a traditional large frame AR10. If this is primarily going to be shot from a fixed position and not carried thats probably the way to go.

Howevever, if you are looking at a more multipurpose rig, then weight and balance are a huge factor in the usability of the rifle. Given that I would definitely strongly consider small frame AR10s.

I have the 18" revolution and love it. Accurate and reliable, though admittedly I only have a couple hundred rounds down the bore so far. I wouldn't even consider a traditional AR10 unless it was a pure precision rig or I was on a tight budget. And if I was on a tight budget, I wouldn't buy an ar10 as I wouldn't be able to feed it.

POF is coming out with a budget version to compete on price with the SFAR next year. I think that would be a much better option than the problematic SFAR or the various budget ar10s.

With all that experience, I'm curious what your thoughts are on the Daniel Defense DD5's. They're certainly in that price point and reviews sound good.

I agree with what you're saying about the 6mmARC or other calibers. There's a lot of advantages to that and I'd consider buying a 6arc upper if I knew an outfit that made a great one. I keep checking white oak armament to see if they have one yet and I haven't seen one yet. The 6arc would be great, but I also still want to get a good semi auto 308.

Check out Grendel Hunter if you wanted a 6mm ARC upper. I bought one of their complete 22” uppers and it’s very accurate and reliable. Just dropped it on my lower and bought some mags.

 
Maybe beyond your budget, but a lmt mws is now on sale at titan defense for $2,299 if interested.


If that is too expensive, then I have heard lots of good things about the armalite listed above. The sig also seems reliable, but they can be a very hit or miss company when it comes to customer service or just randomly canceling an entire product line.
 
That LMT looks like a great deal. I haven't done much research on LMT over the years, but I think it's used by the Brits? Maybe? As far as the difference between the defender vs MARS series, I don't have a clue. I'm not necessarily looking for the budget entry model version.

That armalite looks like a good deal at a great price. If I got a preference I'd prefer the 18" barrel just to keep some of the blast down. I also like how the armalite doesn't have all the ambi controls. I grew up on a 20" A2 and all the proprietary ambi controls just throw me off. I know I could train in some new muscled memory, but I don't see the advantage to the extra parts when I'm a right handed shooter.

Honestly I keep going back and forth so much on this topic and I'm trying to figure it out before the black friday deals hit. All I know is I want an accurate and reliable 308 that I can scope, suppress, and run pmags in.
 
PWS MK218 16" has been very good for me. 100% reliable, good tunable gas block and turned out to be a very accurate platform. Proprietary parts and has to be sent to them for a rebarrel are drawbacks. Put in a trigger and it's a hammer in the 5-700ish yard range. A bit iffy to 800 and falls off a cliff in that range with SMK's.
 
@teddy12b There are just a few differences between the mars h and the defender. The mars h has full ambi controls, a 2 stage trigger, a sopmod stock, and a winter trigger guard. All of that would be easy to fix in the future if you are on a budget.

The LMT MARS H is in use in a number of places. The UK, New Zealand, Estonia, along with lots of rumors posted on various gun sites about smaller contracts for groups like the Swiss special forces. It has a monolithic upper, which makes caliber and barrel length changes take about two minutes with a wrench. Barrel types offered are also chrome lined or stainless steel, heavy and lighter weight profiles.

I own a mars h and love it. Factory 308 and 6.5 CM barrels are available, as well as parts kit for the lower, bolt carrier groups, etc. Reliability is top notch and it works with pmags. Reliability and pmag compatibility were also two big reasons I bought mine from Titan Defense. They are gassed on the heavier side, but that is easily fixed with things like a brt gas tube bought aftermarket.

Those 18” Armalites from PSA are the easy button when they’re on sale.

I’ve never broken anything on either of my Armalites. They both shoot really good and have been as reliable as my LMT’s and SP10. Buy a spare bolt stop and field repair kit if you’re worried about breaking anything.
