I bought this off of here, ended up not needing it. It's a Bushmaster telescoping buttstock. I believe it is 6 position, has (6) holes on the bottom of the buffer tube. Includes: Buttstock Buffer Tube (standard, not pictured) Nut Retainer plate Spring (not pictured) Only looking to trader for: Officer sized 1911 mags: Chip McCormick Wilson Combat Colt Will add alittle cash if your mags are worth more than my buttstock assembly Paypal is the payment that is easiest for me, please send as gift of your pay fees. Will accept USPS MO if needed, however that is the only type of MO I will accept.
