Great stock, easy install.

Fits the B&T APC9SD perfectly! Great price!

Fit my SBR AP5-M perfectly along with the sb tactical folding adapter

I used this to replace an SBT5A brace. The reused bolt securing it to the folding mechanism was quite stiff to reinstall once I swapped in the stock, but not enough that it impeded function in any way. It locks up securely with no wobble or fitment issues. Just as secure as a fixed stock. And because the bolt was so tight, the stock doesn't swing around when it's folded, which actually makes it that much more practical. This stock also adds more to the LOP compared to a B&T model.

Just as I needed at a price that is hard to beat. Coupled with their amazing service, I could not have asked for more.

Works great for me .

Perfect! Fits perfectly into the SB tactical brace joint.

Added this to my SBR MP5K with an sb tactical folder mech and fit was perfect and the stock is the best bang for your buck if you are looking to go this route. Rubber butt pad feels great also!

I ordered this since I sbr'ed my PTR MP5K clone. I already had the SB Tactical brace on it so this was the least expensive way to add a stock. It did require some filing down of the locking block and widening the bolt hole so not straight drop in but didn't take much. Only reason for 4 stars is the required fitting but that is more on the SB Tactical endcap over the actual stock
