First Strike FSC Drop Down w/ On/Off ASA - Installation 

Thanks for the great tutorial, super easy install due to your video - but somehow my dropdown asa leaks air as soon as i put a tank on it and open the on/off..its coming directly from the manometer valve..any ideas ?

As cool as this upgrade is, there is no excuse for FS for not including detailed instructions as well as making this marker easier to work on.

Just in case any who has a 9.1 . I have a video post install for this DDASA to mount. The big thing is you must file off the bulbous square on the rear end of the pistol grip.

I like it. Tho. Its install was a pain with no instructions. Runs great on my 9.1

what is the size of the three long screws?

That is the mosty goofy looking Drop-Down ASA that I have ever seen 😅
