Solid!
Look no further. No seriously STOP! This is all you need. This is the TDP plus some. There is literally no reason to look anywhere else. I’ve spent a lifetime with these firearms. This BCG is it.

Super well engineered and machined BCG
One of the best constructed Bolt Carrier Groups I have used. Period. I have several tested and proven BCG's and trust all of them. I decided to give this one a try after some research, and it did not disappoint. I had a 13.7 that was a little finicky with Buffer weight, ammo, ect. It was a constant adjustment of the Gas Block. I tried this shortly after receiving and it functioned flawlessly. All rounds from weak Steel .233 to full Brass .556 ran great. The BCG that was in there was a trusted BCG brand, which I will not name. This one is a bulletproof design and well made. Follow instructions and degrease the unit when it comes in, then lube. It has a sticky grease coating when new. I disassemble all new BCG's anyway to examine them and see what they are made of. This one rocks. Great, tight tolerances.

Microbest phosphate +
First off I would like to say how fast Arftac sent out my package And how fast I received it! I don't think I've ever gotten order that fast! I ordered on a Sunday night and originally got the nitride but sent email and within 5 min they got back to me and changed the order. Bcg checks all the boxes and great price. Feels solid and has great reputation I can't wait to fire my gun with it.

Microbest phosphate+ BCG
This bcg checks all the right boxes. Phosphate w/chrome, sprinco springs, and the ocks gas key screws properly staked was just icing on the cake. Basically the same as Sionics, Solgw/fcd bcg that I was looking at before I found this gem. I did install the fcd/sotar np3 cam pin on mine. It’s not needed just personal preference. Will definitely buy more when I get a chance to. Also, if you have any dogs leave a note in the comments section and they might throw in a treat for them. Great company to deal with. Order with confidence.

Microbest phosphate+ BCG
Already had the chrome premium BCG (big fan) so I decided to try the phosphate + version. Initially received one with a damaged gas key port, but I notified customer service and they sent me a new one ASAP, along with a prepaid return label. New one arrived in perfect shape and I’m looking forward to testing it out!
