COMPLETE LOWER RECEIVER W/ BCMGUNFIGHTER™ STOCK FOR AR-15 Reviews & Ratings

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.

BCM complete lower

This is my second BCM lower I have bought. I’m never disappointed with Brownells I am super impressed with their customer service. The only reason I used customer service is I had my debit card turned off so they Emailed me instead of canceling.Very happy with Brownells

BCM IS 5 STARS THROUGH AND THROUGH

BCM is one of the best AR-style manufacturers there is. Quality through and through with the customer support to go with it.

BRM lower with BCM upper

Combined a BCM lower with a BCM upper. Lot of waiting as BCM products are out of stock (high demand for quality). Fit together like a glove. No slop. Very happy with the BCM Bolt-carrier group, well constructed, heavy duty and built to last. The only negative is the trigger, bit on the stiff side @ 6lbs pull. No major problem when replaced with a two-stage trigger. 500 rounds through it so far, no jams whatsoever.

Bravo Company Complete Lower

I matched this lower to a Bravo Company upper. Perfect fit and finish. Trigger was a little stiff but Im sure it will only improve with rounds. The FDE matched all accessories. I couldnt be happier.

Awesome Lower

Fit and finish is amazing. The high quality you expect from BCM. You get what you pay for. IMO BCM has the reputation of making extremely high quality MILSPEC products, they are not race cars. Please ignore any reviews under 5 stars. Do you pay a little for the name? Sure. But you are getting the quality they are know for. If you want to be picky about Milspec parts, dont buy a complete lower, buy a stripped one and put whatever parts you want in it. If you are looking for a solid milspec lower, this is it.

GREAT SERVICE!

The process of purchasing a firearm through Brownells has been nothing but good. there is even a FFL Dealer locator that has a number of choices that are pre-approved for transfer services. I purchased a lower receiver, choose my FFL Dealer and about 5 days later I picked it up at my local Gun Shop. It was all very convenient and a great source for FFL items. Thanks Brownells!

Excellent

I ordered and received item in a very reasonable timeframe and the entire process was seamless. Very good updates as well throughout the process and never once worried about whether or not I would ultimately receive the product. I will absolutely be purchasing again from Brownells and they've reinforced my believe in their company.

Nice Piece

The nicest lower I have, matched it up with a BCM upper! Haven't been to the range yet? Recreational, target , varmet shooter.

Best in the business

Another fantastic product from BCM. Add a BCM bolt carrier and upper so you can be confident it will work every time. If you trust your life to your rifle this is the one for you.
