Peice bolted on very easily, works great once secured. Only negative feedback is the included screw wore down the first time I screwed it on and had to be replaced. Other than the screw price works perfectly.

Overall a rock solid add-on.
But the flat head #1 Phillips screws are NOT hardened. When final tightening, 2 of the 3 heads stripped. Maybe no biggee... the blue threadlocker should hold everything tight.
The finished installation works nicely.

No brainer when it comes to this product. Real easy to install and have had zero problems.

It fits overtop of the stock bolt release nicely, except, it's so tight and adds size, it smacks against my upper and has scratched my upper receiver now. Returning, don't need products that scratch or damage my firearms.

it fits mi sig m400 perfect i love it

I got tired of waiting for the Tactical (always on back-order), so I decided to try this one. Works great, i like the fact it has 3 screws to tighten down. Plus it's cheaper and looks cool. I'm using it on my build from 80% Arms. Used a little blue loctite for securing the screws. Now I might have to get a charging handle to match! Never ends, does it?
