The consensus by most about the GPC is that it should be able to meet or exceed the performance of the 308 while using military type green bullets or the make it possible to engage the enemy using the 7.62x54 with 24" barrels. The firearm should be typical configuration of current use. Carbines 12-14.5" barrels, DMRs 20"barrels or less, LMGs short barrels for dismounted and possibly 20-24" for mounted. The ammo should weigh 20% less than the 308. The recoil should be as little as possible to help controllability of the firearm.
The AR15 is not large enough or strong enough to handle a more powerful cartridge in combat conditions.
