AR-15 M16 A1 LOWER RECEIVER Reviews & Ratings

Designed in conjunction with Nodak Spud, the BRN-16A1 Lower Receiver matches the features of the original M16A1 Receiver. Perfect for a “Retro” or reproduction build, these lowers precisely mirror the original profile. Features specific to the BRN-16A1 Lower Receiver are the proper M16A1 front takedown lug profile, and profile surrounding the receiver extension. Most forged lower receivers produced today feature “A2” profiles, which are incorrect for M16A1 reproduction builds. The lower starts off as a 7075 T6 aluminum forging, then is machined to mil-spec dimensions. Once machined, the lower is finished with a matte black hard anodized finish. This finish matches modern uppers found on the market today, as well as the Brownells M16A1 Upper Receiver sold separately. Standard AR-15 components will work perfectly with this lower. Simple, engraved markings on the lower include:

Model: BRN-16A1
Cal: 5.56mm
Mfg: Brownells Inc

This lower is the proper receiver for the following reproduction builds:

M16A1
Model 619
Model 629
Model 630 / GAU-5A
Model 639
Model 649 / GAU-5A/A
Model 651/652
Model 653/654
Mk 18 Mod 0
Mk 12

ATTENTION BUYERS!!!!!!!!!!!!!!!!!!!!!

ATTENTION!!! THIS IS NOT AN M16A1 LOWER!!!!!!!! EXTENSIVE MACHINING REQUIRED TO MATCH AN M16A1 SPECS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I purchased 2 and this is my 2nd review

I find it dishonest and unnerving that the review I left the first time was not approved. Just like the first one this one was obviously black and had been over stickered as gray in an attempt to dupe the buyer. The customer service reps were told, made promises, agreed to have warehouse inspect and still sent one that was black with two stickers, one black description covered with a sticker that said gray!

Very poor finish, had high hopes

The receiver is freaking PURPLE! I thought the color wouldn't be so bad once it was together, or I thought it would grow on me. I wanted something to match my Colt upper from a build kit. Not even close. In the picture the upper rifle has an A4 upper from Armalite, the lower is the Brownells lower. Notice how it's kinda VERY PURPLE! The bottom gun has a Colt A1 upper which is grey, and a lower from the 90's which is close, but I wanted something better. Overall I am very dissapointed. I collect firearms and wanted something to match my Colt rifles that I could use as a range toy. If you just want a range toy this might work for you but if you are looking for an authentic look, look somewhere else.
