Do you use a standard ar15 buffer tube for an AR10?

The AR-15 Bolt catch should work on KAC/DPMS type lowers, but not AR-10 type lowers.

From DnPRK: Most AR trigger assemblies will fit an LR-308. The two triggers that require modification are 1) the Chip McCormick straight trigger which needs th end of the trigger clipped to clear the trigger guard and 2) the RRA trigger which might require the tip of the cocked hammer to be clipped to prevent it from dragging on the bottom of the bolt carrier.

An AR-15 rifle buffer tube will fit an LR-308, but you need the 308 rifle buffer and spring.

A CAR-15/M-4 collapsible stock buffer tube will fit an LR-308 but you need to use a Slash shortened buffer and 308 spring, or use Armalite's collapsible stock buffer, tube and spring for the AR-10 carbine.

Guess I should have read more before posting. Thank you.

Not with the AR-10.  The AR-10 is a ArmaLite made rifle.  The DPMS LR-308 carbine uses a AR-15 tube and shorter buffer.
