My barrel started life as a DPMS AR-15 16" Heavy Barrel, Pre-Ban, Chrome moly, 1x9 twist barrel with full sight radius, with bayonet lug and threaded muzzle: not chrome lined. It has a full length gas system. I had to open the gas port to 0.125" for it to cycle all rounds fired: M193, M855, Swiss GP90, Radway Green SS109, and even 62 grain HP Wolf. Since I opened the port, I have had no short cycling problems or feed problems. It runs 100% with my DPMS A2 upper and DPMS B/BC.
I added an 11 degree target crown.
I had Adco contour the barrel under the handguards to a lightweight profile.
It does not have a sling loop/keeper on the FSB because it was free floated, and the sling attached to the DPMS ventilated, full length, free float tube, which I will thrown in for $30 if the buyer wants it: not sold seperately.
Barrel has fired 700-900 rounds fired through it. The best I can group is about 2 MOA with Swiss GP90, using iron sights and a bench bag.
I have nine photos posted here:DPMS 16" dissy barrel
Overall condition is very good. Photos show all.
$120.00, delivered. PayPal, money order, and personal checks OK.
I am selling this barrel, because I am switching to a 16" stainless steel barrel, with full length gas system, without a flash suppressor.
Feel free to email me with any questions, and I will email your answer along with editing this ad with the information. I am a firefighter/paramedic and work 24/48; so, I may not be able to respond for a day or so if I am on-shift. I do respond promtly to remail when I get it.
Edited to add:
It does not have the standard handguard cap for standard handguards; it was built without it on the FSB, because it was built as a free float barrel.
