Will a standard AR15 A2 buttstock fit onto an AR10?
Thank you, Phessor

yes, they fit.

AR10 buttstocks are a little different (internally and externally) than my standard Colt and Bushy A2 buttstocks. But they do fit. Armalite even has separate part#'s for AR10 and AR15 buttstocks. I wonder why this is?

According to my catalog, the following are COMMON parts for AR10/.308 caliber and M15/.223:

EL0090 Buttstock screw (A2)
EL0110 Buttstock Assembly (A2), black
EG0020 Buttstock Assembly (A2), green
EL0120 Rear Sling Swivel
EL0122 Rear Sling Swivel Screw
EL0130 Buttstock Spacer
EL0370 Rifle Receiver Extension (AKA Buffer Tube)

The Buffer and Operating Spring are obviously different, but looks like everything else in the A2 Buttstock is the same.

I got my info off the Armalite website under (.223 stripped lower receivers and parts)
linky


"A2 Buttstock Assembly - Does not include buttstock spacer, standard buffer, standard buffer spring or standard receiver extension
Green M15 EG0020 $40.00
Black M15 EL0110 $35.00
Brown M15 BR0040 $40,00
Green AR-10 EA1120G $40.00
Black AR-10 EA1120 $35.00 "


I agree they are probably the same. I really don't like the hollow feel and sound, mold flash, color, and clear plastic insert so I switched mine out to a standard run of the mill A2 stock.

Very interesting!

Further up on that same page, they show the EL0110 as the ArmaLite A2 buttstock for both the AR-10 and M-15.

But at the bottom of the page they do show different part numbers for the M15 and AR10 A2 buttstocks from Eagle Arms.



My best guess is that they may still be trying to separately account for ArmaLite and Eagle Arms parts for some kind of internal accounting reason. Maybe?

I still think either one will do, but interesting observation.
