 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 offering 2 styles of upper receivers. One style is the slick side style that incorperates a bolt on shell deflector and no forward assist. The other style incorperates an integral shell deflector and forward assist that are machiend right into the upper. Both styles utilize a standard AR-15 ejection port cover. We are offering extra uppers.

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.

The first production run of Modern Sporter receiver sets is sold out and we are currently accepting orders for the second production run.


We are currently in production of the slick side uppers to go with the currently sold lowers, we anticipate these being done before the end of 2018. Then we start to manufacture the F/A upper which we expect to have done either late March or early April at which point we will then start on lowers again, which should be done by July 2019.


We will start new production run of each part as soon as possible but it is impossible to provide exact dates for completion of each.


To keep a cycle of complete receiver sets getting out we are limiting production runs to about 200 pieces of each, and are shipping on a first come first served basis for each part.


So far our predicted target dates have been achieved and we do not foresee this changing.
