Hey guys... sorry if this is a repetitive question, but I haven't been able to find the answer via search here or google/etc and I am on a time crunch to order parts. I'm building a 16" DPMS pattern .308 carbine... I have an LMT SOPMOD on my AR-15 that I'd like to transfer over, so I need a receiver extension it will fit on.
So is the standard AR-15 buffer tube exactly the same and compatible as long as I use AR-10 buffer & spring? Or is that a shoddy fix and I should just buy the DPMS or Armalite carbine buffer tube?
Thank you for your time and sorry again for being a noob to 308 ARs.
The SOPMOD stock will fit on any milspec carbine receiver extension tube.
You have two main choices:
AR-15 (from many manufacturers)
AR-10 tube from Armalite or Vltor.
The only practical difference is that the AR-10 will make your collapsed stock 5/8" longer.
AR-15 tube: get a stubby (2.5") buffer from DPMS or Slash.
AR-10 tube: get an standard AR-15 sized (3.25") H3 carbine buffer, or 9mm buffer
Both can use an Armalite buffer spring, you may need to trim.
