For AR platforms chambered in 22, theres only 2 manufactures to consider. Colt and Smith & Wesson.
Colt is just slightly higher in price. The Smith comes in a few different variants which is cool. Magpul has a contract with them so they have the MOE furniture on one of the versions and a performance center version as well.
Cool thing about the Smith and I believe most of the Colt, is that you can change most of the parts with 556 version AR's. Stock, grip, sights, trigger, etc can all be interchanged between the S&W 22 and 556 AR rifles.
The Mossberg 715T is absolute garbage. Would never recomend it to anyone. AR style shell molded ober a reciever and barrel is all it is. Mossberg makes great Shotguns. Not good rifles.
