Microbest BCG
This BCG configuration cannot be beat, especially for the price. I've always sourced parts for this configuration individually, and I wish I had found ARFTAC sooner, because you cannot build this anywhere close to what it's being sold here for, plus no more fighting with extractor spring pockets or surfacing gas keys and staking(which theirs is perfect) Also, comes with a sticker.

Not Pretty, But gets the job done!
Just got in this Premium Cosmo (BLEM) BCG. The carrier has a dull nickel type look to it as if a layer of chrome plating was missed. A few scratches on the none-ejection side but nothing deeper than the plating. I have the regular premium and side-by-side the regular one has a far "shinier" and deeper chrome finish. It is just prettier. The bolt itself is 100% with no issues on it. For the price this is an amazing value as the BCG will spend it's entire life inside the upper anyways. Great buy!
