What is the difference between those bolt carrier with the grooves cut out on the sides and the ones without the grooves? Difference between light and heavy bolt carriers? Other than staking, anything else matter with regard to carriers? Anythign special about bolt/carrier fitting? |

-I've never heard of a bolt carrier nowadays that specifically does not have forward assist notches (the grooves that i believe you're talking about). Unless you're trying to build a die-hard retro gun with no forward assist, just go with any carrier. -I'm assuming by light and heavy carriers you mean the difference between an AR15 and M16 bolt carrier. There's another thread out there that talks about that. -No, and No. Buy a quality bolt carrier group and you can't go wrong. That way you don't need to worry about doing the stake job yourself. |
Some DPMS rifles are made without the forward assist (grooves). Most other companies that sell such things use DPMS parts. Avoid them.
Light as in the lightweight carriers made by JP and Young made for regulated gas systems/competition use? Or AR15/M16? The M16 carrier has some additional weight, in a civilian rifle, the primary function of the M16 carrier to delay the unlocking of the bolt, which is a good thing.
Yes, many things matter. But if you buy an LMT or Bravo Company bolt carrier, those things will be taken care of.

Just for some extra info, what are the many things that matter with regards to the fitting? I was just wondering...The only thing I thought was different was the material, testing of material, finish of material, and staking of the carrier key. Not argueing just wondering

Sorry, not with regard to fitting. You got the main points - composition of steel, testing, finish, staking. For example, Bravo Company is out of complete BCGs at the moment because they are waiting for a higher quality gas key. |
