Microbest is as good as milspec phosphate gets
Excellent phosphate bcg for a mk12. Was looking for a BCM when I came across this deal for the OEM maker of BCM. Excellent quality and super quick shipping and communications with ARFtac. Win win. Will buy more when available.

Microbest bcg
For the price or even higher, phenomenal bcg. Ran it hard this weekend and did great. Shipping is absolutely amazing from Arftac! Plus, a sticker and we all know that’s why we buy parts.
