THIS. Problem is the stock is fixed and a bit longer than what she wants. So, can someone tell me how to change it to an adjustable stock? I don't believe it is as simple as buying the adjustable stock from Magpul. I believe you have to change the recoil tube and the stock spring. Please advise. TIA
So this isn't a big problem, you will need to replace your "buffer", "buffer tube", and "recoil spring" to Carbine from Rifle..
If you log in to 308 AR Forum, it will be on that forum somewhere? If you are brave, you can join and ask, but I would recommend a heavy carbine buffer, 5.6 ounces, maybe and orange recoil spring, and carbine buffer tube compatible with the DPMS platform, it is slightly different from the AR10 platform, although both DPMS and AR10(ArmaLite) are generically referred to as AR10's.

So you will need a heavy 2.5" Heavy Buffer, (5.6 oz or so), 7" M4 Buffer Tube, and I would probably go with a lighter than the orange spring, maybe the Hot White or Blue on the Sprinco website... PM me if you like??
The challenge will be matching the buffer, spring, and gas output of "YOUR" rifle, once you do this, you may not be able to exercise your Smith and Wesson warranty
