Very pleased. Plan on buying more.

My first AR build. Added this to an Anderson lower and I could not ask for more for the price.
<br>The lower parts when together easily with few tools. The upper assembly was already put together and fired. I have about 200 rounds through it with zero issues. The adjustable stock rattles, just like the stock on my buddy's M&P15. The dust cover is difficult to snap closed, but I suspect that will become easier with time.
<br>If I can edit this review, I will update with accuracy remarks.

Follow Up Accuracy


I am not able to justify buying high-dollar optics right now, however, this rifle kit continues to deliver. The bulk of the ammunition I've fired has been "Red Army Standard" 56-grain steel-cased el Cheapo rounds and I have experienced ZERO failure to feeds, failure to fires, or failure to extracts.
<br>One nit-picky complaint: trigger pull. Mine was close to 7 pounds with a willy-nilly break point. I used the trusty Dremel tool on a few edges and replaced the spring. It now breaks like a glass rod at 4 pounds. Not perfect but let's be realistic.
<br>I use Magpul Gen M2 and Gen M3 magazines.
<br>Initial accuracy at 100 yards was 2.5" groups with cheap Simmons Deerhunter 3x9x50mm scope.
<br>After the trigger spring and Dremel tool I was in a 2" group. Note: I am not a deadly sniper. The barrel's accuracy is better than my skill and optics level, AND this is with bulk ammo. Take care.
