The first step to determine fit is to assess the type of lower receiver that you have. Brass Goat is compatible with a typical AR-15 mil-spec lower receiver, as shown here. [Accessories and exceptions shown below].
This includes these AR-15 cartridges:
|✔||Right-handed ejection upper receiver||X||Left-handed ejection upper receiver|
|✔||Extended Mag release||X||Side charging upper receiver|
|✔||Magpul BAD lever||X||Extended takedown pins|
Brass Goat now has a dedicated mount made to fit the Smith & Wesson MP 15-22. Select this mount in the 'Options' drop-down before purchasing.
