Used this forged lower as the foundation for my NRA high power match gun. Very pleased. Even had the hole at the back of the receiver to allow for the additional of an upper tightening plug. Very happy with the ODG coating also. A+++ on everything.
Both of the trigger guard ears on the left side are noticeably taller and thicker. There were smaller grey streaks in the anodizing above the grip
Purchased the C4 Lower for a project, great quality and quick shipping. The website made it easy and they notified me of shipping. Highly recommend.
Tried them all... BCM, DD, AERO, PSA.... Centurion is absolutely the best quality lower available on the market today.
The CM4 is an excellent forged receiver. Consistently within spec, aesthetic roll mark, and a good price.
Got referred to Centurion by a friend. I now have a 16 inch barrel and a new lower. Gonna buy only these from now on. Great company, excellent people excellent product.
There is a reason these are out of stock everywhere. Quality lower and great customer service.
Beautiful ano , extremely tight tolerances and tight fitment. Best company out there by miles.
