M231.  Wire stock for preban AR15.  Slides forward around the lower receiver.  Has a buffer tube something like a pistol buffer assy.  I'll send a pic if it would help.
Thanks,

I bought 2 last year from CMMG for $60 each, w/o buffers or springs. I bought 2 springs and CAR buffers later. I decided to sell one in December, asking $65 and was told by several other members that they could get them for about $45 each. Needless to say I withdrew my sales offer, and decided if other members could get a deal that good they sure did'nt need to consider buying the one I had for sale. I would think that with the "rarity" of these particular stocks sale/resale value would be considerably higher.              loose-round

How do those stocks feel in use?

I usually find folding/wire stocks uncomfortable.
