I'm thinking about building an ar10. What parts are the same? Can i use an ar15 stock and do i need a different buffer and spring? also what about grips and rails? What about detachable sights?
All lower receiver parts are interchangable except for:
Takedown pin (EA1113)
Pivot pin (EA1112)
Magazine catch (EA1108)
Bolt stop (10203100)
It is generally cheaper to buy an AR10 lower parts kit (EA6010) than to buy an AR15 LPK plus the proprietary AR10 parts.
To install a rifle length stock, you need an AR10 rifle buffer (EA1090) and AR10 operating spring (EA1095).
To install an AR15 carbine length stock, you'll need a CAR-10 Buffer
and an AR10 operating spring (EA1095).
AR10s accept AR15 pistol grips.
AR15 rails will not work on AR10s.
Art at www.SuperiorWeaponsSystems.com
makes the best AR10 rails on the market. The E1 is lighter and stronger than any other I've seen.
You can use any AR15 rear BUIS.
If you use a gas block mounted front BUIS, you'll probably need a taller front sight pin.
If you use a rail mounted front BUIS it will work fine.
An AR15 mag catch "can" be used but it won't engage all the threads on the push button.
Just buy the AR10 kit
