Great bcg tight specs - KAK Industry K-SPEC Enhanced Bolt Carrier Group

This is a great BCG it came well lubded. On arrival I looked it over then tore it down to inspect it in detail. Couldn't find any faults with the product design and assembly. I took it down for a short range trip with suppressed 300 subs and supers as well as 556. The down venting gas is a nice addition without adding an extreme amount of extra grim to your mags. Basic finctionality was also spot on.

The only negative I've run into is that the bcg seeems to have trouble ejecting and chambering the heavy 300 sub rounds.

So results may vary based on ammo etc. I had an extra Anderson Manufacturing BCG with me that ran all the same ammo without issue.
