Have only a couple left. Brand new USGI M3 50 BMG barrell. it is about 36" in length, chromed on the end and stellite lined. Wil work on M2hb too. They are excellent for making a 50 BMG single shot out of. That is what i did. The barrel is of a heavy profile that gently tapers towards the end. The end tapers back upslightly. You can have the end threaded as i did to fit any of the common 50 BMG muzzle brakes that are out there. NEW IN WRAPPER/TUBE. I have had these for about 20 years. $225.00 plus $20.00 shipping. I do PAYPAL too at firstname.lastname@example.org PICS also available.
