i am brand new to the 15-22 world. your conversion looks great! i didn't know you could do that with these guns.
you didn't happen to do a diy on this, did you?
I just gathered the parts that were mentioned on this board. There is a video somewhere here that is helpful. It doesn't really go into the barrel nut/delta ring in much detail. I had to figure out how the delta ring parts went together, really simple once I thought about it. Here is a list of what you will need to to do the exact same thing I did, adjust as required to suit yourself.
Tacticool or ShoeBoy barrel nut wrench (both are advertised on this board, your call)
Tacticool barrel vise jaws (I'm cheap, I got by with a couple of blocks of wood in my vise, but the right tool would be much easier)
TrueShot Technologies A2 front sight.
Tacticool freefloat handguard adapter nut
AR15 barrel nut wrench
AR15 barrel nut
AR15 delta ring parts (delta ring, circlip and spring)
AR15 carbine length foregrip and front cap
AR15 carry handle (you get what you pay for here, I would shop for a quality take off, but that's up to you)
Front sight tool
I will give brief instructions below:
