Should I Switch Bolt Carriers?
Hi,
I read here a lot, and yes, I've searched regarding what I'm going to ask about, and no, I haven't found a definitive answer, yet.
I have a 14.5" mid-length. It's less-than-top tier (CMMG), so I figure it's probably over-gassed.
Before you say anything, I bought it before I knew better, and dumping it and buying something else isn't an option.
I've already followed the advice in the old "Oh No! I bought a BM/RRA/Stag [CMMG]" sticky, and after 1,000 rounds or so it hasn't had any problems.
Following the consensus here about 14.5" mid-lengths and buffers, I bought an H and H2 buffer to try.
I installed the H2 and it cycled fine, even rather dirty (after using my .22lr kit). I honestly couldn't notice any difference in recoil.
So, I figure that it's probably still over-gassed, even with the H2, and more reciprocating mass might be a good idea.
Of course I replaced the CMMG bolt with a BCM bolt right away, but I'm still using the semi-auto CMMG bolt carrier (yes, the carrier key is staked properly).
My question:
Should I replace the semi-auto carrier with a heavier auto carrier? The difference is less than an ounce (per weights posted by Robb Jenson), the cost is about $70.
Should I try an H3 buffer, too? This would add almost another ounce of reciprocating mass.
Or should I just do nothing and keep shooting it?
