RA-Tech Steel Outer Barrel for KWA USP Tactical Airsoft GBB Pistol

"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%.


****Warning****

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.

"This along with the 112mm inner barrel work just fine for the standard USP NS2. A 112mm inner barrel is a must so that the inner barrel is stable inside this outer barrel.

"Got this for my NS2 KWA tactical USP .45 and it's pretty sweet! Has a nice weight to it with a cool storm cloud grey color too it. My one complaint is that I think the threads are 16mm counter clockwise, but still is a thousand times better than the stock outer barrel. I would definitely recommend it to anyone's compatible USP.

"No adjustment needed to use with everything but the compact. Adds weight looks nice great product

"GREAT outer barrel! I absolutely love it. One of the best accessories for the KWA USP money can buy. Drops in easily with NO sanding, NO filing, and no other modification needed.

If you're like me, and also have the KWA HK45, this barrel WILL fit, and will function just fine, but it will rattle a bit.

Overall, a great addition to the USP. It's definitely a must!

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

YOU NEED TO CHANGE INNER BARREL IF YOU WANT TO USE THIS STEEL OUTER BARREL!

"BOUGHT IT AFTER READING A REVIEW THAT THIS WILL FIT TO KWA HK45, IT DID NOT FUNCTION PROPERLY!!! DO NOT BUY THIS ONE FOR KWA HK45 OR YOU WILL WASTE YOUR MONEY.
