"You can not fit stock inner barrel with this one. They should include this in the description.

"This product does every thing right. It fits into your HK usp full size perfectly with no modifications. It adds the weight so it feels nicer in your hands and racking it back sounds so much better. The only thing is that the threaded are 16mm, not the standard 14mm. I don't know why they couldn't just make it 14mm since every ting else is in 14mm . So if you want a silencer or a flash hider, then you will have to buy a 15 dollar adapter. That is my only gripe since it does not say in the description that it is 16mm.

"Very High Quality Piece, appears forged and machined, not cast then machined. Finish is the greyish phosphate used on real steal.

I do NOT like the polymer barrels, nor am I fond of the aluminum ones, especially where the orange tip is molded onto a extended barrel

Worked perfect, a minute to change out, oil and work slide to break in.

This is for the KWC/KWA Umarex HK Standard USP or HK USP tactical only.

Its a pricey piece but improves the USP 100%.


This does not properly fit the KWA/KWC Umarex HK45. You may be able to get it to work with modifications, but I tried it on my HK45 and the slide hung up.
