No particular order, Colt, DPMS, Armalite, S&W, Rock River, Bushmaster, Olympic Arms, Stag, all work well, and there is probably a few I forgot.

Left to right, Colt SP1, DPMS shorty, Olympic lower with Colt upper, DPMS space gun, with Krieger barrel and Geiselle match trigger.

New DPMS I built for DCM shooting, rock river full float tube under the handguards, Shilen 8R barrel

Iron sights off the bench 100 yards. Needed one more click to the right.



New 3 gun build on DPMS upper and lower, with Shilen 8R barrel.
