FAQs

Comparison FAQs

Can AR-15 and AR-10 share parts?

Very few parts interchange — bolt carriers, magazines, and some furniture differ. Upper and lower receivers are different sizes. They are related designs but not compatible systems.

Which is better for deer hunting?

The AR-10 in .308 Win or 6.5 Creedmoor is the better deer rifle — more energy, better terminal performance, more ethical at longer ranges. The AR-15 in .223 is legal for deer in most states but marginal.
