"Incredible upgrade part. A must-have for HK or GBBP enthusiasts. Drops in securely with a bit of lube. Construction is very fine, with no deformations or blemishes on the phosphate/parkerized finish. Much sturdier than the stock outer barrel. Adds some serious heft to the pistol as well, which raises some slight gas efficiency issues. Keep your gun well-tuned with quality lube and molybdenum grease and you'll have no problems.

Note that this is specifically for the USP TACTICAL, NOT THE STANDARD USP. I have seen reviews and complaints everywhere about this barrel not seating correctly in Standard USPs. Again, this is built SPECIFICALLY for the KWA USP TACTICAL.

"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.
