I'm building an AR pistol (Aero Precision stripper lower, Magpul pistol grip, PSA LPK) and have a quick question about the buffer, tube and spring kit.
I got a steal of a deal on a carbine length tube, buffer and spring, no stock but it can accept one. I'm going to mill off the catch rail for the collapsible stock, but my question isn't a legal one of whether or not it's an issue if a pistol can accept a stock. My question is how well will the carbine length tube with carbine spring and buffer cycle with a short upper. I haven't decided on a upper just yet, still going back and forth over 7.5" and 10.5" barrels. I know the 10.5 is the better choice ballistically, but the 7.5 match grade I'm looking at just looks so nice.
Anyway, will I need to swap to a pistol weight buffer and pistol length spring for proper cycling, or will my carbine kit work ok?
