I overhauled my 15-22 and changed the rail out so the old rail, end plate and barrel nut are for sale. It is in good shape, just look ugly having been painted with rustoleum which can be stripped and repainted (I removed a bit of it).
Asking
$25 shipped to CONUS for the rail and nut.
I also have the almost new (used just the one time) Tacticool barrel nut wrench I won't have use for again -- $15 shipped to CONUS.
SOLD to Lorelei
I take USPS money order or discreet Paypal (No Gift. The fee is already added to the price -- They have been cracking down on 'gifting' in case you haven't seen it yet).
First 'l'll take it' with follow up PM or email gets them.
