Title: Project barrels
Post by: JPSAXNC on November 20, 2020, 10:53:55 AM
I bought two new old stock .22 cal. Duc IL AR6 barrels from Davis at (airgunauctions@gmail.com) One is 25" long the other is 27" long. Both have a threaded section, one is choked. cutting off the threaded sections and choke I can get 22" and 23" of clean barrel length. The barrel od is .443 just slightly over 7/16, they were 90$ each delivered.

Those prices are a little better than buying unfinished liners from TJ's, for comparison TJ's gets around $5.20/inch plus shipping for as-forged, in the white liners.

Have you slugged the bores and measured rate of twist?

Hi mackeral, These are high quality (match grade, IMO) Korean air rifle barrels the bores are very consistent, the twist rate is 1:18  HTH

Hi Bob, I'm assuming he has more, because he asked me how many I wanted. He's been retired for while, but told me he still has 500 guns, and probably a lot of spare parts.

That’s a great source. The Korean barrels that I’ve used have been bigger than your typical Airgun barrel at .221” rather than the “ standard “ .217” . Make great slug shooters .

Hi Hobbyman, I measured the bore diameter at .217 and the groove depth at .221 HTH

Yep that’s on the big side. Sized down .223 bullets work real well or if you’re not scared to spent money , the RWS bullets from Krale at 41 grain work real well. Those measurements are real close to the LW .22lr barrels.
