Hello,

I'm getting ready to drop some cash for a Armalite AR-10A4, but before I do, I'd like to see some feedback on their performance.

They are advertised @ 1.5/2 MOA, what changes are required to get 0.5 MOA.

Is this weapon prone to jams?

I've heard from M-14 people this weapon spends some time at gunsmith for repairs, any opinions?

This weapon comes with a chromed barrel, any predictions about barrel life?

Thanks,
MikeF

Got one.

The chrome bore will last for ever.

.5 MOA won't be easy at all.

You'll need two main things to get there. A $500.00 to $650.00 barrel from Krieger, Rock Creek, or ABS. Also a Rock River Arms two stage match trigger.

There are a few easy tweaks to get it running reliably. It makes a great battle rifle. It is inherently more accurate than the M1/M-14/M-1A system. If you want .5 MOA, get a bolt gun.

You have to pay attention to how you load your ammunition. Get the port pressure right and it will run sweet. Make sure you add a bunna rubber ring around the extractor spring. That is a $1.00 mod.

Before you chunk down bucks on the Armalite, I would suggest that you also take a good look at the new Bushmaster 308's.

For me I'd buy the Bushie for no other reason than it uses FN-FAL mags which are easy to get, don't have to be modified to work and are cheap. In the 223 cal AR-15's I've had the Bushmasters were of higher quality than the Armalites I owned being another reason that I'd choose Bushmaster over Armalite. I've read good reveiws on the DPMS version but would personally consider them third........DJ

Considering the service I just got from Bushmaster, I'd get the Armalite.

My new Bushmaster Super Varmint (or whatever they call that model with the fluted heavy barrel) with a chrome lined bore has NEVER shot a group under an inch for me or anyone else. (I've had two high-power Distinguished Marksmen also try it extensively...)

I had it professionally recrowned locally to see if that would help. It did, very, very slightly.

With it still averaging around 2+ inches for groups at 100 yards, I sent it back to Bushmaster for their appraisal/warranty tweaking. They fired it three 3-shot groups at 100 yards and got one of almost 3", one well over 2", and one of 1.35", marked it okay, and shipped it back to me with the comment to the effect it had been recrowned by someone else than them. No other comments.

I called and was told because it was re-crowned, the warranty was void.

Well, I think that is absolute bullshit!
Anyone with a lick of experience as a gunsmith can look at a crown with a magnifying glass and a square and tell whether it is okay, or in need of attention. This one is virtually perfect, and is a hell of a lot better than the crown that came on the barrel from the factory.

As to the groups being adequate...well the local folks who've been buying Rock River Arms AR-15s locally are getting 0.5 MOA or better out of theirs...

So, I'm gonna buy a RRA upper for mine. and when I get my AR10, it sure as heck won't be from Bushmaster.

Hey Alberta Canuck,



No need to throw the baby out with the bath water.



Go to White Oak Armament http://www.whiteoakarmament.com/ and order a tuned RRA match trigger ($110.00) and SPR barrel ($248.00). Your gunsmith can slap those parts in to your present rifle in about ten minutes (thirty if he has to heat any epoxy holding the fore end tube onto the barrel nut). You will have a 1/2 - 3/4 moa rifle. For an extra $45.00 or so they will send you a bolt head matched to the barrel.



It is easier to get a .223 AR to shoot small groups than the .308.



Just like with bolt rifles, if you want a shooter, you're gonna have to do it yourself.
