"Works great, fits great.

Main reason for the review was a PSA that 40 Mike grenades do not fit unless forced into the launcher. Im going to shave down the inside so the blues will wit, but the reds are too long. You have to hit the slide override to move the hatch out far enough to get a red 40 mike in.

"Have wanted an m203 for over a decade now; finally decided to get one. Barrel mount fits my adaptive armament, though the front clamp doesn't line up with the launcher-step in the outer barrel perfectly. Anything with a thick profile barrel will not fit the standard delta ring clamp without modification: lancer proline and specna arms barrels are too thick for example. Due to the weight and the nightmares I still have over m4 barrel wobble, I wouldn't recommend hanging this off a multi-piece outer.
Rail mount works great, but only really secures the rear of the launcher. To compensate for this, I used the screw holes for the barrel clamp to thread some steel wire through and secure the front to the bayonet lug. I have the long version mounted on a 10.5" barrel ris m4; with an ASG tracer unit the launcher and barrel are equal length. Have only tried it with ASG and MAG brand 40mm shells, but so far very satisfied with performance.

"Bought this to throw on a 16" ar upper for display. Actually fits on the rifle with the barrel mounts and is a lot cheaper than the 37mm flare launchers. Looks pretty cool on it and is a fun range toy to shoot paintballs at your target. Not quite 100% metal. The rear barrel mount is a plastic or polymer so i pull it off when i actually shoot the rifle, could just use the pic rail mount if i wanted to keep it on. Fun launcher and looks pretty cool.
