I'm gathering parts for my first large frame build and i'm wondering which route to go on the barrel. My first thought is to buy either a 24" or 26" Bartlein from Craddock precision. Since this is a gas gun and from what i've read, the large frames are harder to drive, would this barrel just be overkill? I don't own any other large frame AR type rifles nor have i shot any, only bolt action in the larger calibers. For reference the rest of the build will comprise of PSA PA-10 stripped upper and lower, PRI hand guard, charging handle, and gas block for a mk12 mod1 look, magpul PRS stock, JP silent capture spring, JP low mass operating system, Geissele SSA-E, and most likely topped with a gen 2 razor.
