Microbest chrome BCG premium
The OCKS fasteners, phosphate gas key and ejector, and the upgraded ejector and extractor springs all bring great value to an already solid bcg. Excellent bang for your buck, I may need to purchase a few more! Most importantly, my 2 doggos loved the jerky treats provided.

Microbest Chrome Enhanced BCG
The BCG is machined very well. The tolerance on the parts is really good. It seems to hold the lube on there also. I have several BCG's in a drawer not being used. This one is definitely going into my next build.

Microbeast Chrome BCG Premium
Nevermind best for the $, this is one of the best BCG's I've ever seen period. I've used just about every well known and high end BCG out there and with the exception of a few (like KAC & LMT that cost literally 5-6×) there's nothing any of them have or do better than these. Everything from the Springco springs, Ocks screws, great staking, and the buttery smooth finish are just incredible for a BCG at this price point. As always arftac was awesome and shipping was extremely fast.

Premium Hard Chrome Microbest
Sat back and compared my new Microbest to my Sionics NP3. Really don't feel like I can justify spending the extra 100 on Sionics anymore. The coating is just as nice and all the other features that drew me to Sionics are here with the Premium Microbest. Great product

Microbest you're gonna find
Flawless BCG. Just arrived today and I can't find a single imperfection. Buttery smooth inside and out, tolerances exact, passed every test with A+ marks. This BCG will perform for decades to come. Incredible deal, thank you ArfTac!
