We were able to get our hands on the only run of AR15 comps by Jager Products. These were run by Jager for a customer who was building some custom AR15 rifles. The only comps left are the Titanium in .223 caliber. The titanium version weighs only 3.4 ounces. Designed with two large horizontal chambers, two ninety degree vertical ports, and two small "popple" holes slightly right of vertical to prevent torquing. The titanium model has a taper recessed exit hole. Meets the 1" x 3" size requirements for 3 gun matches and has standard 1/2 x 28 threads. Price is $164.99.
