    1. Awesome Rifle (review by J on 12/7/2015)

      This rifle exceeds expectations. Mine is shooting sub moa with a variety of ammunition, even some cheaper rounds. Keeping the barrel cool it is regularly shooting 5 round at 1/2 moa @ 100 yards with Federal Gold MM 168gr. Surprisingly I also got 9/16"-1" groups with federal xm80. Seemed like luck but then I repeated it with three more groups, taking 3 minute breaks between shot groups to let the barrel cool and the holes never wandered more than 1 moa. This is my first semi automatic .308 so I don't have much to compare it to, but I feel armalite did a great job with this gun. The adjustable gas block is sweet. I have it cranked down to just enough to lock the bolt back, but I have yet to have a single FTF feeding it a large range of ammo from 149gr to 180gr. I have shoot 200 rounds thus far so not a ton, but thus far, flawless.

      I followed the match barrel break in procedure prescribed in the manual, which took some time for sure. I have no clue if this method is necessary but I must say the gun is shooting better than I thought a thin profile barrel was capable. The Timney trigger definitely helps!

      The LUTH arms butt stock is awesome, totally solid and light, maybe a little funny looking, but form follows function. I have yet to start playing with the adjustable comp, so have no feedback in that department. But recoil is light. The first time I shot it I could not believe it is 308, however with the comp it is loud.

      I would definitely recommend this rifle, for the price I cannot imagine better performance.

      Center Fire is awesome as well, shipping the gun fast. Ordered on Sunday and they shipped Monday morning!! CenterfireGuns has my business for sure!!

    2. Work of Art (review by Opus on 10/13/2015)

      5 stars to CenterfireGuns for their order processing and delivery! I ordered on a Sunday and was shooting the following Saturday.

      This rifle is a work of engineering art! After cleaning, lubricating and mounting a scope it was off to the range. The gas return is adjustable for the load you're using it comes from the factory set for a wide range of ammo. I ran 147 gr. FMJ; 168 gr BTHP and some 175 gr HPBT to break it in and didn't experience any malfunctions. The supplied Pmag functioned with 2 rds or 24 rds. I'm still fiddling with the adjustable butt-stock which I expected. The muzzle break works great making this rifle a pleasure to shoot. I read about how to tune this to my shooting style and loads; which I plan on doing at a later date.

      All in all I couldn't be happier with my purchase.
