I just did a barrel swap, from a mid gas rainier arms barrel to a carbine gassed Ballistic Advantage with all other parts remaining the same. BA does hint on their sight that their barrels are lightly gassed.
Shot the new barrel last night, and it is super soft shooting for carbine gas. too soft though. It felt like a good middie, without the snap of my DD carbine. I did check the gas block with a can of compressed air, feeling for flow and leaks while the wife sprayed it down the tube. Everything seems aligned and tight.
With some Cheaper 55g 5.56, it would pick up the next round about 50% of the time
With Hornady 75g. it was a single shot affair with an occasional exception.
It is ejecting fine, just not picking up a round.
I want it to stay soft, so I'm debating which buffer to swap to. the standard is 5.33 ounces. options in the lighter direction are 4.56 and 3.80
Do you think the 4.56 will make enough of a difference or should i go straight to the 3.80
i do tend to shoot things like Rem UMC 223 and such so they might cause even less buffer movement, so i was leaning towards the 3.80. I haven't tuned a buffer before so I don't have experience on how much weight makes how much of a difference
What say you?
