300/221 pistol upper
 

Got to try out the 10" barrel on a upper today and the recoil was very manageable. Think I am going to like it. This one isn't going to have a gas system so will decide later whether to leave it a bull or not.

Thought I would add if you get the Pacific Tool reamer you will need to turn the necks if using 223 brass.

Very nice. What were you shooting through it....subsonic ?

Thanks Spook. Actually supersonic although I didn't actually clock any of them. Its a 1:10 and still a work in progress. Possible family member deer gun. I will try to locate a reasonable 1:8 blank for the subsonic barrel.

Can I ask where you got that barrel? I have been looking for a 10" 300/221 barrel and can't find one.

xxxx,

A new job has me a little slow responding to the forums I am on. Started making my own AR barrels a while back and that was one of the pistol ones that I did. Was pleased with the 1500 fps it did but it is naturally loud like most AR pistols unless you put a suppressor on it. I am not setup to make barrels for the public at this time though so I can't help you out. Somebody else here may be able to make a recommendation.

Thsi guy makes off caliber AR barrels in any length you want:

I have already contacted Randal (ar15barrels.com) and he is not taking any new orders until he gets caught up on his current orders.

I am going on 15 months since I put a deposit (50%) down on a 10.5" barrel from Randall. I was quoted 6-8 months. :mad: Now I am trying to get my deposit back.......

He has the absolute worst customer service/communication of anyone I have ever dealt with.

I have heard that alot on some of the boards over the last year or so about Randall. He posts regularly on m4carbine.net.

Yeah, I was looking at his website and it hasn't been updated since 2005. He uses leftovers from other projects to build pistol barrels and their between $225 and $275. He doesn't even know what he has in stock. I had heard that the 300/221 rifle barrels that Del-ton sells use a pistol length gas tube. If that is the case, I may buy one and have it cut down to 12".
