||Overall a well-built airsoft launcher!
Everything is nice and solid with very little wobble, and the included adapters will bolt this to ANYTHING.
I personally have attached this model to the lower RIS rail on my G&G CQB_R Blowback M4.
The fit is very tight and the launcher barrel is similar in length to the rifle's "silencer"
The only issues i've had are that the rifle should not be picked up or carried from the launcher hand grip, there's a good possibility that the barrel will slide open and possibly separate from the carrier assembly. Also the Trigger guard is designed to be held in place on the magazine well body, but with the CQB kit the D-ring is 1/2" longer and the trigger guard has nothing to hold against.
Depending on your D-ring thickness you might have to either tape the trigger guard against the launcher body, or do like I did and remove the guard completely by punching out the holding pin and removing the trigger guard.
Fits almost all barrel types
RIS adapter for generic mounting
Solid feel and construction
Very efficient "spent shell" retractor
Will not stay closed if the rifle is picked up via the launcher
Trigger Guard may not attach correctly with aftermarket barrel/RIS setups
Barrel Scratches Easily
