WTS: Atchison 22 cal conversion for AR15/M16

[Compglock]

Used Atchison 22 cal conversion for AR15/M16. I bought from EE years and it’s just taking up space. Unit is clean and oiled with light wear no burrs.
Comes with:
1 original steel mag
1 full size Black Dog Machine mag
2 Black Dog Machine mags which show cracks
$300 pp fnf, @pplecash or cash FTF.
prefer FTF near west Indy but will ship with tracking with cost added to your zip
