Bushmaster Bullpup M17S 223 Rem.

Read Gun Tests Rating and Recommendation

Not the most attractive rifle we've tested, Bushmaster's Bullpup is about the minimum-size weapon needed for the .223 cartridge. It's designed for scope or dot-sight use. The rear magazine placement took lots of getting used to. This rifle was a tackdriver, but difficult to prove because of a very poor trigger.

Right off the bat we were impressed by the fact that this design was really all you need for efficient utilization of the .223 cartridge. The rifle was compact, slick looking, and seemed to be totally modern in its design concept. It was, however, too heavy for the round, as was the Robinson, we hasten to add. But the Bullpup did have an integral carry handle, topped with a sight rail for easy mounting of accessories, so it was at least a portable design. Also, if you want a lighter AR-15, Bushmaster makes ‘em, but not in this short design. The main rifle body was formed of aluminum in the form of a rectangular tube with rounded corners. It appeared to be an extrusion, because it had no obvious machining marks on its outside or inside, but it had some integral lugs machined into its lower surface to hold the front carry-strap swivel, and to accept the lower trigger/magazine/grip assembly. If in fact it was machined, the quality of the work and subsequent finish was outstanding.
The Bullpup was actually a clever design, well done except for the trigger link. The rigidly mounted barrel gave excellent accuracy.
The Bullpup broke into its field-stripped mode in seconds, once two captive pins were drivenout. The arrow points to what we thought was the weakest point of the plastic trigger-group carrier, but this thin area is well protected with the rifle buttoned up. The bolt carrier rode on two springs. We thought the Bullpup was a clever design that would be well worth owning.
The safety is just behind the trigger. Three pins held the trigger group to the main tube. The forward one, just in front of the trigger, was the hinge point.
