Not recommended

Bolt face quality is horrible. 03/10/2018

The bolt face lugs are horrible quality. Sharp and dig into barrel lug making it difficult to extract a round but hand and causing extraction issues win shooting.

Slightly recommend

Poor quality, damaged my barrel 25/02/2018

The leading edge of bolt lugs had a sharp edge all the way around that bit into, and gouged the breech of my barrel causing the bolt to not fully rotate into battery. I didn't realize I had a problem untill the breech was damaged enough that a round wouldn't fully chamber, by then the damage was done.

I did get it to function again by lapping the bolt face and polishing the edges. However it would require sending the barrel to the manufacturer to remove the barrel extension and polish the breech to completely repair damage.

Good not Great 24/02/2018

This is a nice looking BCG, the machining is very, very smooth inside and out. It functioned flawlessly, was easy to clean and for the price I think its a good value. If the heat treating on the 9310 bolt is good, it should last, Only time will tell. My main complaint is that after 60 rds the nitride finish has warn off the first 16th" on both ends of the BC rails. This makes me believe the nitriding is thin. The finish still looks good inside the BC where the bolt and gas rings slide back and forth. I have several types of BCGs with dif coatings, NiB, NP3, chrome, and Life Coat some with 100s or even 1000s of rounds on them, they all wear on the rail ends eventually but not this quickly. Nitride is a good finish coat but this is obviously a little thin. If you are trying to save a buck this is still a good BCG.
