Elite Force Gas Magazine Rebuild Kit (Gun: HK MP7 Navy VFC Version)

"I bought this kit for the replacement valve only. I planned to use it to rebuild a 1911 that shoots BBs instead of Airsoft. The dimensions of the valve were exactly the same, and when I replaced it, the new one leaked. I watched this video from Elite Force on rebuilding the valve on a 1911(https://www.youtube.com/watch?v=8o7KSMXTUls), and it explains that the included o-ring needs to be installed for the valve to seat on. I don't remember removing one from the original valve, but this was the "silver bullet". After installed the o-ring, the magazine holds air.

This was done on a Sig Sauer We The People 1911 BB Gun. It is also compatible with the Tanfoglio 1911 and numerous others.

"All stock KWA parts. No thrills....I have one of the KWA MP7s from before Umarex’s license with H&K became exclusive. It has been my main primary for about 10 years or so. People have told me that the KWA is not any good, because they heard from a friend in a forum from somewhere, where it’s ok to throw your gun down the stairs and say it’s a piece of junk.....My gun has run flawlessly for close to a decade, thousands of rounds, without failure or expensive upgrades. I have 4 flawlessly running 40 round magazines and a 20 rnd one with a leaking fill valve and base gasket. So I bought the kit. Fill valve is the same as the 40 rnd, but the base gasket is smaller....

Pros: all KWA oem parts that work.

Cons: does not fit the 20rnd magazine

"These are an amazing solution to leaky mags, i have three mags 2xregular size and 1x extended magazine I used the kit on all of them and it fixed there pesky leaking . 2 of them were completely useless i would tighten the co2 in and they would expel all of the gas out the top untill i rebuilt them that is! this is an amazing product when used properly. Keep in mind the co2 puncture part is counter clockwise. and the spring is obviously not going to work with the extended mags but they often don’t wear out anyway. DONT THINK TWICE END YOUR LEAKS HERE. NO NEED TO BUY NEW MAG WHEN YOU CAN FIX YOUR ORIGINALS . :)
