I think he (the op) is trying to make a .22lr colt commando.
Yeah Commando that’s what I was thinking. Anyway I’ve given up on conversion bolts and slow twist barrels for .22lr. They run fine, but zero accuracy after 50 yards. I have a 4.5” Ar-22 build with a CMMG Arc barrel and bolt that will ring a 4” gong all day at 100 yards. I’ve got a left over A1 upper sitting around and figure I could use the lower off that gun for this upper as well. The Bettermag adapter allows the use of MP 22-15 mags and they run flawless on top of being super easy to load.
I can install my own FSB, and have a few extras laying around.
Then get the barrel you like, the length you like, and then drill, taper ream, and taper pin your FSB on. I think an a1 would look pretty cool as a dedicated 22.
I may just have to go that route. I was really hoping someone had an off the shelf available.
I haven't kept up with all the various new crop of AR parts companies but I don't recall anyone doing the specific thing you seek off the rack. Unfortunately. It is a very cool idea.
I was also thinking about getting a set screw FSB and dimpling an off the shelf 10.5 barrel. It won’t be battle durable, but should still work since it’s only a .22lr. Without the gas block shoulder it might be a little tricky getting in exactly the right spot. Are there any good companies still cutting and threading barrels for a reasonable price? Right to Bear has a dedicated M4 clone that would work perfect if cut down to 10.5”
They are very responsive to inquiries too.
Here’s the 4.5” pistol I’ve spent way too much money on for a .22lr but it’s one of the most fun guns I have.
Oh that's cool. Laptop case probably holds that nicely.
That's quite a find. Wish you had not shown me that
Not a true dissipator, but still very cool. This is a Kino configuration from BCM. It's a carbine length gas system but a Mid length sight base. You get optimal gas timing with a more convenient sight radius. I got this same upper for one of my SBR's.
