Out of stock


The RSA-AKP was designed to replace the sling loop on the NAK-9 pistol and allow the installation of braces or stocks on an approved SBR. It can also be installed on most AK pistols by simply drilling and tapping your rear trunnion.

Drill size for tap: 8.5mm

Bottom lip prevents the adapter from rotating when installed. 

Not compatible with SAM7K-34 or Zastava M92/M85 (this requires RSA-YAKP).

Attaching a stock to a pistol makes it an SBR and requires NFA approval. You are responsible for knowing and following your local/state/federal laws!

Great easy addition to the NAK-9 for my SB 1913 folding brace. Mine was already threaded so easy swap.

I added one of these to my NAK-9. Went on without a hitch. worked perfectly and super sturdy.

ABSOLUTELY phenomenal

Absolutely positively 100% perfect. Had this installed on my Romanian Draco (went to a local gunsmith because I do not trust myself enough not to screw anything up) and it is phenomenal. I had a sig folding mech laying around and threw my SBA3 on it. JMAC products are top tier and they 100% have my attention and business from now on. 5/5. They hit it out of the park with this one.
