Hello all,

Is the ar-10 trigger group the same as an ar-15? Also is the buttstock assembly the same as the ar-15?

Thanks for viewing!

Someone else may want to chime in, but as far as I know the trigger assembly is the same except for a stronger spring. Some aftermarket trigger groups are also caliber specific. Buttstock is the same.

You can use an AR-15 trigger on a .308 gun but it may not strike 7.62 surplus primers hard enough to ignite all the time. It is suggested to use the AR-10 triggers on the .308 ARs. I think I have one in mine and I rarely have problems. As for stocks, same thing but say if you want a Magpul PRS, get the AR-10 one. I have an AR-15 one and it works but the charging handle cant go back all the way. So i just cant toggle the bolt catch manually, but it just barely doesnt go back all the way. Other than that stock you should be fine

The hammer is bigger in the AR10 TG.

Ok here ya go.

Rifle length stocks use the same tube as ar15. but the buffer is shorter. And I beleive it uses a different spring.
as for carbine you would normally use a longer carbine tube made for the ar10, although they do make extra short ar10 carbine buffers that work with the stock ar15 carbine tube.

The trigger question has already been answered. you CAN use an ar15 trigger but most dont recomend it.

You'll notice that there is some overlap between the AR15 and the AR10 parts. :)
