ABC/R has finally made its way to 7.62mm, LR308 pattern ARs.  ABC/R v3 has incorporated refinements and lessons learned since the ABC/R (v1, 5.56mm) was introduced in early 2015 and v2 (2017 to 2020). ABC/R version 3 differs from v2 in the paddles design.  V3 features a ledge on top of the upper paddle, and bottom of the lower paddle for increased traction.  Due to the non-standard based nature of 7.62mm AR platform, many of 5.56mm ABC/R v3's features would introduce incompatibility issues on 7.62mm ARs.

These are cosmetic only, they don't affect the functionality of the bolt catch.  For receivers with a generous bolt catch paddle cutout, such as Rainier Arms, Mega, F4 Defense, etc. there is ample clearance for ABC/R v2, 7.62mm. Machined from billet 8620 alloy steel and heat treated with a DLC finish. The ABC/R v3 is proudly designed and made in the USA.

Incompatibilities:

• KAC SR25
• LMT Defender .308 and MARS-H
• Armalite AR10B
• 2A Armament Xanthos
• PSA PA10
• Mega

Please NOTE:

• Though the ABC/R v3's upper paddle is angled and tapered, and we have tested it on upper receivers with a small, oval shaped bolt catch paddle cutout, such as found on DMPS's LR308 upper receiver, the upper corners of ABC/R v3 7.62mm may come in contact with receivers and mar it in two small places inside the cutout.
• The ABC/R was not designed for use on 9mm receivers that use Colt 9mm magazines which require a Colt 9mm bolt catch.
• 7.62mm ABC/R v3 is incompatible with 5.56mm spec AR lower receivers.
