Semi-auto .308,
Extremely reliable,
Sub-MOA,
Able to find quality aftermarket parts. (Trigger parts, adjustable butt stock, etc.)

---------

I kind of think I won't find this, at all. I looked into the LR-308, and it does everything I want - except the most important thing: reliability. I found a number of threads complaining about FTF, FTE, and jamming.
The solutions ranged from blowing $100 in ammo while the gun is drowned in oil, putting in an adjustable gas block and resizing the gas tube, to polishing or re-working the chamber - and various things in between. Sometimes, people gave up because they couldn't get it to work right.


Can you suggest any rifles for me? Should I give up and go to a bolt action?
Thanks.

Sub MOA get a bolt gun.

That's what I figured.. I read that the LR-308 can do sub-moa, at least with a good aftermarket heavy barrel (krieger, etc.) I hoped there would be another rifle that is reliable and could do the same. Oh well.

Thanks for the info, mate.
 
Sounds like you have no experience with gas guns if you think sub moa is not attainable...


I never said its not obtainable ( your words, not mine).

I have both and the bolt gun ( IMHO ) is the better sub MOA platform for various reasons.
Buy / build and run what you like they are all just another tool in the box.
 
I say build your own; you get exactly what you want. Otherwise, +1 GAP-10

If by that you mean, take various parts and combine them (trigger group, handguard, butt stock, barrel, etc.) - that's what I was going to do.
But I was going to use LR-308 platform. How do I avoid the reliability issue?

Buying the right components from top manufacturers. I have two AR308 builds and both start with Mega Arms Upper/Lower, JP BCG, Geissele Triggers, and Syrac Adjustable Gas Blocks. Choose a high quality barrel and most any lower parts kit and you are good to go.

Does the upper and lower matter? I saw that someone with a MATEN(?) that had the same issue as other's DPMS.
Thanks for the JP suggestion ;)
 
F&D Defense here in Texas Guarantees Sub MOA with high possibility of 3/8th moa. BTW that's the same thing I was told by the guys at GA Precision and the GAP 10. I ordered the GAP - 10 in .308, and I will be working on the FD338. I know its not apples to apples. But both guarantee the same thing, and the same performance, Yet the GAP 10 had a shorter build time.

You appear to be under the impression that poor reliability is built into the design. It is not. Assemble Chicom copied Rolls-Royce parts and you will NOT wind up with a Rolls-Royce quality vehicle, although the basic design is sound.
 
There are two major issues you can run into.

1. Fitment issue - Buy quality parts from a reputable manufacturer.
2. FTF/fTE -this is mostly due to timing. Use an adjustable gas block and you can adjust the gas system to run reliably

Understanding how to put one together correctly helps too because buying quality parts doesn't guarantee a quality build.

I was, and I'm glad to hear that - it gives me hope. When I have the money, I'll have to make sure I get good advice. ;)
 
M1A loaded. Get it bedded, gas system welded and timed. Load 43.8 grains of IMR 4064 in a federal case with a 210m primer 175 grain SMK. The thing will shoot sub MOA all day out to 1000 yards.

ARMALITE AR10 A4 308WIN 20"STS HBAR 1-10RD PACKAGE

ARMNBS308WINT.jpg




1) Call and ask for the actual ARMALITE model number and verify
2) Give them your $1,199.99
3) Shoot the barrel out
4) rebarrel with a pipe of your choice

Sell the cheap goodies and use the funds toward good glass and mount.
There AIN'T anything else out there than can touch it (if it is a true AR-10T)
in that price range.

I never had problems with my DPMS 308s that weren't my fault, IE improperly resized handloads, crappy mags etc. They grouped well too, on par with my remington PSS and LTR. Maybe a tenth or two behind in average size if you split hairs.

Or, you can get an M1A, that's another popular option. But then you'll have to kiss your MOA or better accuracy goodbye.

*BEST* option is a top tier 308 AR. You'll see lots of guys on here with GAPs, Larues, LMT, POF. There is a reason for that.

As long as it's assembled properly with the correct parts, using good ammunition, magazines, and is relatively clean and lubed there are no reliability issues. You should have no problems with a run of the mill DPMS or Armalite. I see the 20" armalites for 1200 bucks on gunbroker, get that, swap the handguards for a quad rail free float and you'll have a poorman's M110.

MOA is not all that hard to obtain, SUB-MOA is splitting it down by 1/2 again and a much taller order to obtain and hold regardless of the rifle platform.
The M1A / M14 can be a MOA platform. SAGE EBR's averaged better than MOA ( .89 average @ 100 meters / 110 yards) with just a chassis system on the standard platform.


Nothing against any of the gas guns but holding the SUB-moa level is a small environment and dominated by bolt guns.
 
I have had an m1a loaded for about a year and a half now, I recently bedded it into a mcmillan stock using CAL50's guide I think (thanks!). Works well, shoots great, but it is not a sub moa rifle nor an MOA rifle. Still fun to shoot though but if group size is your thing it is much much easier to get a heavy barreled AR10 and a few boxes of gold medal match than it is to find a used M1A loaded, replace all the springs, ejectors, extractor, shim it, obtain a used mcmillan stock from a cranky old marine in Virginia, clean up the old bedding material, prep it, get the acraglass kit, watch the videos, experiment with different release agents to find the one magic one that won't stick (the one that comes in the bedding kit is worthless), then slop it all together, tip tie it being careful not to fully close the trigger guard as to not apply too much pressure and squeeze too much bedding compound out from under the heel of the stock, then stick it in the safe and wait 24hrs with your fingers crossed that you didn't just permanently glass it together.............
