This item is a perfect fit for my MKE AP5 MP5 clone. The RSA-MP5 adapter shipped and arrived in just a few days, way faster than I was anticipation. The adapter fit snug and only required some mild tapping to get it to fit. The quality and craftsmanship is top notch. If you are in the market for a different set up to your MP5 this and a 1913 Stock/Brace are a solid way to go.

Excellent product just as described

I just got this in the mail. Installation did require a rubber mallet like the description said. No issues, mp5s are always finicky when changing the rear cap. Works great and feels amazing. Installed a mcx folding brace and it’s looking sweet.

Look, stop staring at this magical piece of machines marvel and just buy it. As soon as this RSA hit my mailbox, I skipped my happy butt out and got it, skipped back and tore the package open while grabbing my HK MP5. This thing fits! It’s slightly tight but as soon as I got it on, the pin hole lined up perfectly! Paired with the JMAC stock with the 1913 folder it’s straight sexy! The vertical rail allows you to adjust up and down on the stock so you can line up your sights with the cheek well. I’m so glad I found them and will be using them for future firearms parts.
