The SR-25 ECC and ECR have the URX 3.1 rails.
There will be 4 to choose from:
SR-25 ECC $6250
The SR-25 16” Enhanced Combat Carbine is the flagship weapon for KAC in 2012. The ECC System features a 16” 5R Cut Rifled barrel, precision chromed to add longevity, resistance to fouling and corrosion, and a 762QDC Flash Suppressor. This weapon system is also equipped with the URX 3.1 configuration which allows shooters the advantage of an MIL-STD-1913 Picatinny Rail, yet the comfort of a slimmer, more contoured handrail.
SR-25 EC $4760
Our 16” Enhanced Carbine takes precision to a new height with its Match Chamber and 5R Cut Rifled, Match Chrome Moly barrel with a 1:11 twist. This weapon system is truly designed to squeeze the most precision from a 16” .308 platform.
SR-25 ERC $6098
The new KAC 20” Enhanced Combat Rifle is based upon improvements for a 20” Duty System. This system features a 5R Rifled Match barrel with a 762QDC flash hider that effectively eliminates muzzles flash and allows the family of 762QDC suppressors to be easily added. The ECR also boasts an enlarged Ejection Port and Carbon Cutter bolt carrier which allow for improved reliability when firing suppressed or in less than ideal environments.
SR-25 ER $4498
KAC’s SR-25 20” Enhanced Rifle utilizes several features already equipped on our carbine weapon systems, which were introduced to the upper receiver in order to increase reliability when firing the weapon with a suppressor. Additionally, the 5R Cut Rifled Match barrel features a Target Crown to maximize the accuracy of this barrel.
