Seems like Retro ARs or Clones are all the rage lately. TROY has introduced a few retro models, Colt announced at the NRA Annual Meeting earlier this month that they will be bringing back a limited production run of some of their most iconic rifles and now it looks like Brownells will also be dedicating some effort towards bringing quality retro components to market as well. Listed below are the first of many offerings from Brownells with more becoming available in the near future. 

XM177 Flash Hider & Grenade Ring 
The Brownells XM177 Flash Hider & Grenade Ring is the appropriate reproduction piece for your Retro carbine build. This flash hider mirrors the original device’s exterior dimensions, as well as flash hider cuts and grenade ring. The XM177 Flash Hider fits 1/2-28 threads, is machined from 8620L steel and has a black oxide finish. Flash Hider length is 4.335″ and with the grenade ring, bring the total length to 4.45″.

–  XM177 or Colt Model 610
–  XM177E1 or Colt Model 609
–  Colt Model 619/620
–  XM177E2 or Colt Model 629

–  Colt Model 649 or USAF GAU-5A/A


M16A1 Upper Receiver 

Designed in conjunction with Nodak Spud, the Brownells M16A1 Upper Receiver matches the features of the original M16A1 Receiver. Perfect for a “Retro” or reproduction build, these uppers precisely mirror the original profile. This match is only possible by utilizing forgings with the proper profile built-in.

Features specific to the Brownells M16A1 Upper Receiver are the original A1 profile, with no shell deflector, A1 rear sight housing and proper carry handle contours. The upper starts off as a 7075 T6 aluminum forging, then is machined to mil-spec dimensions. Once machined, the upper is finished with a matte black hard anodized finish. This finish matches most modern lowers found on the market today, as well as the Brownells BRN-16A1 Lower Receiver sold separately. Upper receiver does NOT have M4 feedramps.

Standard AR-15 components will work perfectly with this upper.

This upper is the proper receiver for the following reproduction builds:
–  XM16E1
–  M16A1
–  Model 607
–  Model 609 (XM177E1)
–  Model 619
–  Model 629 (XM177E2)
–  Model 639
–  Model 651
–  Model 653
–  Upper is not compatible with Anderson Mfg Lower Receivers due to rear takedown lug depth.

Please note, Nodak Spud does not machine these receivers. Only the forgings are sourced from Nodak Spud. Please contact Brownells with any inquiries or concerns.


AR-15 M16A1 Lower Receiver 
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.

Brownells M16A1 lower receiver 1Brownells M16A1 lower receiver 1Features 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

As someone who has never done any Retro/Clone builds but have always wanted to, these definitely interest me and I am excited to see what else Brownells plans on bringing to the market. There’s just something awesome about seeing the history of the AR-15/M16 and its many variations. Good on Brownells for helping us have the ability to create our own clones of those awesome rifles. 

Whenever the Star Wars fans talk about “Clone Wars” the only thing I think about is AR Clones. One of these days I will have a collection of retro clone rifles like the MK12 Mod1, MK18, etc. AERO Precision has a really awesome special edition M16A4 line of products that would make for a great clone build. The M16A4 has a 20″ barrel, rifle length gas system, A2 stock and grip and the upper has a detachable carry handle which can be removed to make room for an ACOG or other optic. AERO Precision offers stripped lowers, complete lowers, complete uppers and complete rifles so whether you are in the process of building your clone and need parts to finish it off or if you just want to buy a complete M16A4 clone, they have the parts you need. Check out the details and pics below.
