BCM COMPLETE LOWER RECEIVER W/ BCMGUNFIGHTER™ STOCK FOR AR-15

A long time popular item with many Brownells customers, the BCM® AR-15 Complete Lower Receiver is a perfect choice when building up a no-nonsense AR for defense, training, competition, or any situation where reliability is a must.

Whether you are looking to simply do a “Two Pin” build by attaching a complete upper receiver or you are building out a customer upper, the BCM® Complete Lower Receiver is an easy and dependable way to complete your build.

Machined from 7075-T6 aluminum forgings with a Mil-Spec hard coat anodized finish, the lower receiver is completed with the BCM® small parts that keep this receiver as reliable as you would assume with the BCM® reputation.

The trigger is the BCM® PNT™ trigger which has a nickel teflon finish and is un-notched to be compatible with 9mm use, and the BCM® trigger guard gives extra space when shooting with gloved hands.

The popular BCM® Mod 4 Pistol Grip comes standard on the lower receiver. A BCMGUNFIGHTER™ Stock is available in your choice of Black and Flat Dark Earth on a Mil-Spec receiver extension which also includes a BCM® QD Endplate and staked castle nut.

BCM4 Lower

One of the better, dependable lowers you can find. Mil-Spec fits good on quality uppers. Recommended.

Great lower

I've only put a few hundred rounds through my rifle since getting this lower but I like it. The trigger is nice and the stock is superb without any of the normal slop but I have to say a ambi saftey wouldn't have hurt. I'd absolutely buy it again!

B+ complete lower.

I have not shot this lower very much but I will. I bought it because I have several uppers and I wanted one lower to switch to each of the uppers. So far it is doing great. Trigger may be a little stiff but we will see as I put rounds through it. I think all and all it is hard to go wrong with BCM.
