Thread: 300 Blackout Suppressor - fixed the bastard...

Hmmm, is yours Pistol length or Carbine length gas system? Typically, Pistol length is great for Subs but Carbine length can take some work. Mine is Carbine length and I had to open the gas port a smidgeon and I've taken all the weights out of the buffer.

975 yards is more like it for that RUM of yours Steve. That'll get you doing some math.

Today I worked up a load for my match AR, 69 grain SMK's at 2900. Not grouping as well as I'd like, I think they're seated too deep but I need them to fit in the mag. It'll do, it's only for the Service Rifle Nationals in 3 weeks...
