 Our ATRS Modern Sporter brings to market a high quality, great value direct impingement non-restricted semi-automatic rifle specifically designed for the Canadian sporting enthusiast!  This receiver set brings customization to a whole new level, offering "DIY gunsmiths" the opportunity to build their own rifle, selecting any common parts they'd like.  These receiver sets are compatible with standard mil-spec AR-15 parts including lower parts kits, bolt carrier groups, barrel extensions, charging handles, triggers, handguards and more accessories. Going a step further the magwell is EDM'd for flawless feeding and magazine fit with STANAG magazines and features a generous flare for faster, easier mag changes.  The finish is Mil-Spec Type III hardcoat anodizing.

We are selling these receiver sets and extra uppers as stripped units. The receiver sets will include the rear crosspin required to retain the back of the lower but do not include any other internal parts. The uppers do not come with an ejection port cover or forward assist hardware.

We can offer complete rifle builds, complete extra uppers or other small parts required to complete a build. These options and accessories will be dealt with on an individual basis. Call or email for more info.
