Elite Force Airsoft Gas Gun Rebuild Kit (Model: HK MP7 KWA Version)

"This kit doesn't have the piston recoil guide and spring pictured on the product page for the Glock 17/19 VFC version. I'm guessing that they upgraded the blowback nozzle and housing to the latest G18CV2 blockback version in their lineup and so had it reflected in this rebuild kit. If you're looking for the piston recoil guide, you will have to buy it separately (https://www.evike.com/products/87384/)

Otherwise, it's a perfect replacement kit for the latest EF Glock17 Gen 4 that I have.

"I got this kit for the KWA mp7. Out of the kit I used the return springs, hopup, gasket, and flute valve. This pretty much restored a broken gun back to out of the box performance. Solid kit!

"I got this rebuild kit to replace the broken internal hammer and ended up using the whole kit since the other parts would break eventually. The end result was a working gas blowback pistol!

"The rebuild kit came in good time and good condition.
I used them in the KWC 1911 blowback bb pistol, and it worked fine.
The piston seal did not have the o-ring that the original had. But it seems to work fine.
At least the o-ring can't get jammed up in the air nozzle like the original one did !
I did not find a tool in the kit either!
Keep looking up! Ken.

"Absolutely perfect fix for my 1911. Had the smaller spring mess up and this completely has the gun running great again. Now to order a few more to have on hand so that i have spares and i also can now build my 1911 Tac. Thank you very much Evike for carrying this product

"It's a parts kit full of OEM parts. It worked for my clone, though I didn't see any tool that came with it.

"It’s a decent kit, it’s just a shame you can’t buy the cylinder return springs separately and that they only come with one pair for the price. Piston seal is good, the valve is fine. I got a cracked/broken nozzle in the rear which was annoying so I had to buy another one :/ but the kit is a good buy, it just sucks if you get bad quality control stuff.
