"3.2 pounds of awesome. Fair warning if you aren't inclined to workout and build your arm muscles and use a sling with your rifle, get the plastic one. Okay lets move forwards. Overall I was highly impressed with this launcher. It fit well sort of (I have an isse with my delta ring being loose so thisisn't S&T's fault). It fired my shower shells and foam projectiles fine.and I didn't have an issue with the slide stop. I do hve one warning and it's for you front wired people:

YOU CAN BARREL MOUNT A FOREWIRED AEG WITH SOME SLIGHT MODIFICTIONS. Let me explain how I did it. I undid my fuse box and rain it to the left side of the barrel and the non fuse wire to the right so that the tamiya connector was on top of the barrel and wires on the sides with them allowing room for the barrel clamp to slide into the delta ring and not pinch the wires as it came up. You will have to have a handguard with room to mount a battery up top as well as remove your fake gas tubes or run it to an external PEQ Battery Box.

Now onto my one complaint. The spring retension in the front barrel clamp is absolute poorly assembled. China quality there but it's the only reason I won't give this thing a perfect score. I actually had to ind a 37mm real steal clamp to attach to lock things in place.

That being said, I am a happy grenadier If you don't mind the weight or modding your front wiring to fit, go for it.

"Overall this is a great launcher for the price. However, mine had some issues..

-hefty (could be a con go some)
-came with different attachment points
-great look on any AEG a attache it to

-off center (wouldnt matter to some)
-RIS attachment was loose

This is a nice looking and functioning launcher for the price. It’s a solid durable metal (which is a pro to me) and works like a dream! However, my main issue with this that was listed in thr cons was that the RIS attachment was loose. This made it near impossible to use on your gun without it wobbling around. I solved this by added a layer of electrical tape and now it fits perfectly fine. Evike did offer to replace it but i’m fine with adding a bit of tape and it works just as I said. I would recommend this launcher if your looking for a solid well performing launcher.

"i like this because if you have something like a g&g dmr m4 it looks so bad ass it makes some people think twice and it also really works well in the perfect conditions it'll take a small room of people a.s.a.p and it hurts like heck just get a few shells when you order
