Armament Technology Variant AT1-C24 Rifle

 This might be thought of as a standard US Army M-24 sniper rifle “given the Canadian treatment.”  Most of the changes are in the machining and finish of the parts, which gives the AT1-C24 a smoother action than the normal M-24.  The rifling twist has been improved in a manner similar to that of the C-3A1 to improve the performance of the rounds fired from it. 

The barrel is made of stronger and better-quality steel,  giving it a life of at least 10,000 rounds.  The normal fiberglass stock is replaced by one made of Kevlar, and can be had in several colors or color patterns.  Three versions of this rifle exist; the AT1-C24 fires 7.62mm NATO ammunition and is fed from an internal magazine; the AT1A-C24 fires 7.62mm NATO and is fed from a detachable box magazine; and the AT1M-C24 fires .300 Winchester Magnum and is fed from an internal magazine.

 Standard versions of these rifles have no iron sights, but  instead come with a MIL-STD-1913 rail for mounting a telescopic sight.  However, iron sights, are optional, as is a suppressor.  The AT1-C24 is listed as being used by “several police agencies.”
