Bear Creek Arsenal M16 Cut 7.62x39mm Complete Bolt Carrier Group and expo arms H3 buffer have gotten me 100% reliability shooting wolf as well as a correctly timed ejection pattern. I have 2 running these parts.

extremely pleased!!!

Nice shooting upper...seem to prefer Monarch and Hornady over TUL for accuracy, shot quarter size shot groups @ 25 yds without fancy benchrest using pop up iron sights.

awesome upper with bcg/ch for the price

by -

Upper is not 1/10 but in 1/9.5 which supposedly better. Barrel extension is not nitrited. Also came with bcg and ch. So i didn't have to get separate bcg. With h2 buffer all shells leave rifle at about 4-5 o'clock. Handguard is not as refined as i would like but at this price with complete upper with bcg and ch, i cannot complain.

Flawless and Excellent Value

This was a great deal on sale! Pair this with an AIM Surplus NIB 7.62 BCG for reliable military primer ignition and C-Products Duramag 7.62x39 Magazines and you have a 100% reliable and accurate AR-47. Sight in at the range was flawless. Zero issues with Wolf ammunition. Use at least a 4.0 oz or heavier buffer.
