Great buffer!

I got this to go in an 11.5 inch PSA pistol with a springco blue spring. It really gave that pistol a more refined impulse feel. Can't ask for more than that!

Perfect upgrade

Bought this buffer to control the operation of my FRT-15 drop in trigger. It absolutely made the whole operation a lot smoother.

It's a H2 carbine buffer

It's an H2 buffer and works

Great quality.

Great Brownell quality for the price. Their buffers are good to go.

Superb Buffer

When I received the Buffer, I did check the weight. I ordered the H-3 buffer and weight was correct. This Buffer is for my 4' Barreled 9mm Pistol and it opereates perfectly. I immediatly ordered another one for my 7.5" barreled Pistol. I am confident it will perferm perfectly also!!!!
