I am going to purchase a 450 bushmaster upper

I have a lower that has a   AR-15 Silent Captured Spring Gen 2 H2

will this work or has anyone used it on a 450B

450B was designed to run with a standard carbine buffer. I use mine with a Spikes ST-T2 without issue, but that doesn't mean all will run that way. H2 is heavier than the ST-T2.

I talked with jp rifles today
He said would not be a problem
He said the H2 should be just fine
If the bolt was working to hard just add a tungsten weight and that would make it H3
Thanks for everyone’s help

Actually if your having issues you would most likely want to reduce the buffer weight not increase it.

He said to slow the bolt down if it was slamming back like to much pressure, like when you run a suppressor
