Okay here is the 411 on the 7.62x51 AR10
The cardinal rule with them is DON'T MIX PARTS BETWEEN BRANDS. Unlike the AR15, nothing is standard. You can't swap parts around. Only the mags.
They tend to be 1 to 2 pounds heavier then most other 7.62x51 semis
The current AR-10 offerings are NOT like Stoner's original AR-10 design. The current AR-10 is an upsized AR-15. The original AR-10 had a MASSIVE bolt and bolt carrier group. Why? This is because the 7.62x51 makes a LOT, and I mean a LOT more gas then the 5.56x45. That is more gas and crud being belched into your action by the direct impingement. Fire around 500 rounds and you will start seing failures to go in battery. The millitary is having the same issues with thier M110 7.62x51 AR10 type. Stoner fixed this by making the orginal AR-10 bolt and bolt carrier group much much larger then the ones in the current AR-10s. The larger BCG have more moving mass to deal with the larger amount of crud, and it has more surface area for the crud to spread out on.
Ignore my last paragraph if we are talking about a piston AR10. The piston obviously solves the issues.
Mags used to be the AR10 worst problem, they used to used bastardized M14 mags. But thanks to Magpul, that is is thing of the past.
The lowdown is, a little porky and they crud up too easy.
