"Stuck one in my tm 40 rnd extended 1911 mag. Fits great no leaks. It never came with one so I figured ay. And it worked! Lol
I'll take it!

"They seem very high quality and should serve their purpose well. However, they did not fit on my 1st gen Tornado grenade's valve no matter what I tried. I ended up damaging one trying to smush it into the valve (like shown in the video). That said I don't regret the purchase because I'm sure they'll come in handy for other gas valves.

"Got some for my double eagle rebranded jag arms shotgun(they are known for the leaky gas tank in the full stock) and it works flawlessly now. Also if u want to a cheap, reliable, gas 3/6 shot shotgun, then check out the de rebrand of the jag arms scatter gun.
