Works as described. No seal issues so far. Great!

ok guys so iam going to give you the short version here with a link to my video on youtube as well so we are able to get 60 shots out of this adapter on the sig MCX how ever when it comes to accuracy that will fal off after 25 to 30 shots so you will need to compensate for that to get the 60 shots.. 1 bottle of co2 gas is woth about 1 dollar you get 250 shots from 1 90 gram or 88 gram bottle shich is fine but if your not shooting the gun all day or for some time later youll waste the remaing gas in your big bottels as you can not leave gas in the mcx or mpx long term as this can damage the seals according to sig , now my mcx will hit 460s with a 90 gram and with this adapter it get 400''s which is great the speed does start to go down after a few shots but its ok its not a huge loss till you get to some of the higher shot counts, now i have the dual 12gram adapter as well and it lost alot of FPS i was wel undedr 400s with it in the mcx so that did not thrill me and again its 2 bottle so 2 bucks but the speed was the problem i had for the loss of speed being able to try this adapter out and the results made me very happy as well. so its woth going with this single 12g adapter good shot count good speeds .. and no more big bottles to worry about anymore so i can now have my fun with my mcx fire of 6 rounds or so een running 2 bottels in a day is 120 shots i can fire off and have my fun and no wasted gas anymore and i save a budel now to on my co2 for this gun as the 88 and 90 gram are also very epensive to here is the link to my review on this adapter also one more point i had to mod my sig mcx to get the umarex 2x12 gram adaper where this one is a perfect screw it in and shoot no mods will have to be done so loads of bonus's all around for this single 12 gram adapter which can also be used in other airguns as well that have the same thread in system so its not just for the mcx or mpx either .. any how here is the link for the video and a huge thanks to airgun source for sending me out this adapter https://www.youtube.com/watch?v=B8plOlYfaBY
