Solid fit

Solid fit on PTR 9kt. Perfect connector for mounting SBA5 brace via Apex hinge. Better color and finish than the PTR piece too! Absolutely recommend.

A3. Strike stock for MP5k

The quality solid fit. Little hard to install, but all in all great piece!

Way better than the other guy

Should have went with the A3 first. I bought the "Other Guy's" first and my pins where hard to remove or install. It's almost as if A3 knew what they were doing when they machined the part. Buy this one first and you'll save money.

True inventory

They had the inventory they advertised unlike too many other sites. It shipped quickly and arrived quickly. Quality part and could not happier.

Good, but not as shown

The adapter I got is solid and fits my AP5-P well. Problem is: the one pictured is the older modular version that allowed for removal of the pic rail and direct mounting of their folding hinge, and the one I received is a single machined piece of aluminum. Good, but not the picture on the website.

Works perfectly!!!

Perfect fit

Perfect fit but recommend installing the clamps from the side and not dropping down. I installed one side of the clamp and pushed the rail from the front and not the top. Was much easier to finish the install

Not great

I ordered this along with a folding brace and ball detent pins. I noticed a lot of wiggle in the brace arm and figured out it was this adapter that was wiggleing. I tried the factory detent pins with no luck. This stock/brace adapter has a lot of play in my SP5.

Good product

Had to file down the lower portion to fit my Zenith SP5T. Was just slightly too big when I received it. Take down pins that came with my Zenith also did not go back in properly and had to be modified. No fault of A3 tactical, I just need to do better research next time.

Great product, a “little” tight on my AP5-K. After installed with some persuasion, 5 star product.

Great addition to my firearm. Works as advertised and very happy with my purchase as always. Shipping was prompt and will be back for more soon.

Perfect

This thing is solid. I don’t feel any wiggle or any play. Perfect fit and versatile. Highly recommended.
