Any opinions on a #4. Not sure I like the takedown feature. How does it affect accuracy if at all? This one I’m looking at is a sleeved 22LR.

Here’s a rifle I built from a Stevens Favorite which is basically the same barrel hookup as the number 4.  The barrel slides into the frame and is retained by the lower screw.

The target shows what it can do.  The red dot is 3/8 inch.  While not target quality I didn’t think it was to bad for a cheap Green Mountain barrel and that barrel connection.  Now if I could just hang a target rightside up!

The solid frame ones are better as they won't shoot loose like the takedown ones. Otherwise fun little guns.

Yesterday at our monthly collector OAC gun show a friend brought a very unusual #4 over that he just won at an online gun auction. It's a #4 that began life as a solid from in .32RF with full octagon barrel, and got converted by AW Peterson of Denver, Co. to a shotgun. Peterson bored out the rifling so it just barely removed it all, but I could just note a trace of the remnants of it when looking closely. He then turned the forward half from the forearm down to typical shotgun thin style round, and added a shotgun bead.
Peterson removed the threaded area on the barrel and sleeved the receiver, then fitted a #4 takedown lever and rod to make it a takedown. He also cut down the top of the receiver ring to make the bead front sight easy to see.
The whole gun was very nicely color cased and aged to about 60% on the receiver, and 95% barrel bluing. Still in .32RF, but for shot. I happen to have a box of .32RF Shot cartridges made by UMC with wooden shot capsules that are 3 piece and made to separate on exiting the muzzle. He's begging me to sell them to him, but I really like having this neat old box of ammo.

I would think that a Lock Tite product might be available that would make the barrel easily removeable if needed.
