AR10 Question(s)

[bigdawg86]

Ok I am getting a Quentin Defense 80% AR10 and I am confused about parts interchangeability. Can someone verify / answer these questions? I have searched and found some answers, but these remain.

You can simply answer yes or no, explain need be.

1.) QD AR10's are DPMS Style lowers

2.) Armalite AR10 LPK vs DPMS AR10 LPK are interchangeable, but the uppers and magazines are not.

3.) AR10 BCG will fit either DPMS or Armalite style uppers

4.) QD AR10's use standard mil-spec AR15 buffer tubes, but spring and buffer are different.

I believe bolts are different, have have to correct bcg for matching barrel afaik

4.) QD AR10's use standard mil-spec AR15 buffer tubes, but spring and buffer are different.

Yes.

Somebody correct me if I'm wrong as well.

Bolt carriers are interchangeable.
Bolts are supposed to be, but may not be in some cases.
Check the headspace for both minim and maximum spec when swapping 308 bolts between different manufacturers.

For rifle stocks, you use a standard rifle buffer tube.
For carbine stocks, there are extended carbine tubes that run an extra heavy ar-15 length carbine buffer or there are short length carbine buffers that allow you to run an ar-15 length carbine buffer tube.
Make sure your parts are compatible of problems will ensue...
