Posted 9 Jan 2017 (edited) Used colt carbine hydraulic buffer, was used in 9mm sub machine guns. $150 shipped. If you need more pictures just let me know and Ill send you them. I will accept usps money order for payment. I do not take paypal because they are anti gun. Email is best way to get a hold of me, rtonking250@yahoo.com Thank you Ryan.
