Description

ACME-X Adamantium plating provides a higher hardness, significantly improving performance. A harder surface greatly reduces the coefficient of friction and the adhesive force, resulting in lower wear and longer life. This ability is further enhanced by using our ACME-X Cerakote coating on outside surfaces MORE INFO.

The enhanced bolt carrier is designed to reduce carrier tilt/cant during recoil and increasing reliability by strategically relocating key bearing surfaces. The enhanced carrier has fewer points of contact resulting in less friction area and the slight increase in carrier mass extends dwell time and ensures proper gas pressures for reliable extraction.

• Material: Case Hardened 8620 Steel
• Finish: ACME EN-X Adamantium
• Gas Key: 4130 Steel, attached with Grade 8 hardware and properly staked into a milled “valley” to ensure proper positioning

This is a very slick bcg. It is premium quality and feels like holding an alien artifact in your hand.

Nice Machining Very comparable to some of the bigger name brands. The machine work is very clean and the coating is only outmatched by its performance

Posted by Ken P on May 5th 2018

Good Quality I ordered this BCG and received it in just a few days. It appears well made and the coating is exceptional. I am still waiting for the receiver group to use it in so will update when have actually fired a 1000 rounds or so through it. The finish feels really slick but will be using it well lubricated and will review how easy it is to clean and if the finish stains or flakes.

Posted by James Shoop on Mar 2nd 2018

FCG Receive the Bolt Carrier last week. Upon inspection I found no burrs, no rough edges and very good tolerances all over. Put the piece in one of my uppers and off to the range... set up a mag with 10 rounds to give the BC a chance to impress me.... I did not see or feel any irregularities.. Re-loaded and fired a controlled group of 20 rounds ... 5 at a time... again just great. Came home removed the BC and was reallllllly impressed.... it cleaned up in a jiffy, even the bolt face cleaned up with just a Q-tip.... Yup this one is a keeper..
