From the Slide Fire FAQ:
In order to install the SSAR-15® on a rifle its design must match that of the standard AR-15. Some rifles do not allow for pistol grip removal or the trigger modifications necessary for reliable rapid fire. Colt® and Mossberg® are two brands that we know have compatibility issues. Slide Fire® has not tested every .22LR AR-15 on the market, but we have tested the S&W® M&P® 15/22® and it works great!
Several considerations must be taken to maximize recoil on any .22 LR platforms. One necessary adjustment is to install a lighter trigger than stock. Enough forward pressure must be applied to pull the trigger, but a standard pull trigger requires so much force that there is not enough recoil to return the rifle to firing position. For the same reason, it is absolutely necessary to apply as little forward pressure as possible. It may be necessary to practice different holds or firing techniques before you get used to the feel involved. Finally, it helps to start with a light rifle with very few attachments and to use good-quality, high-powered ammunition. Neglecting to account for these factors will likely result in issues such as light strikes, poor trigger reset or feed problems.
