The Lantac Full Auto Bolt Carrier Group .223/5.56 is machined from 8620 steel with a QPQ (Quench Polish Quench) nitride coated black finish. This BCG features shrouded forward-facing gas ports that allows the system to run with a smoother energy pulse. The tail of the carrier has a flared boss helping improve the lock position with the upper and increasing accuracy.

The included Lantac CP-R360 domed head cam pin is machined from stainless steel and hardened for extra strength. The unique, domed style head is designed to curve away from the receiver’s internal surface and help reduce wear. The flat face on the dome head allows it to be inserted the .223 / 5.56 bolt carrier without removing the gas key.

The best BCG

by -

I shoot supressed, and the gas in my eyeball drives me crazy. This BCG alone won’t fix the issue but in conjunction with an adjustable gas block, a radian raptor SD charging handle and using a larger caliber suppressor than the caliber you are shooting it makes a massive difference to the point where gas in your eye is no longer an issue. And in general this BCG runs noticeably smoother and better than any of my other BCGs
