This compensator and handgrip was designed with the army-r45 used as reference. Although this should fit on to any detonics r45 airsoft pistol (TM or ...Army). I used a thin double sided tape to attach the compensator to the bottom frame of my pistol, holds on pretty well. The baseplate addition for the magazine is meant to friction fit onto the bottom of the magazine, though it is very finicky and loose. This is a free version which includes a small maker's mark on the side of the compensator, if you do no want a maker's mark, the paid for version is available in my profile if you wish to support me.
