If you’re referring to the Smith & Wesson M&P15 (standard AR15 platform rifle), then yes — our BG15 is compatible with most stock M&P15 rifles, as long as they have:
-
A standard mil-spec lower receiver
-
A smooth magwell face with a raised fence
-
A right-side ejection port
If you’re referring to the M&P15-22 (.22 LR version), that model is not mil-spec and requires our dedicated 15-22 Brass Goat version.
And just for clarity — the Smith & Wesson Model 500 (.500 S&W Magnum revolver) is not an AR-platform firearm and would not be compatible.
