RPR "trainer" $799

The chassis is the same as the larger calibers.I own a 6.5 RPR and had a .223 RPR.The 223 take weird property non-pmag magazines.They are ar10 length mags with modified feed lips to hold the smaller 223 rounds.Ruger scrapped my 223 but I still have the mags.I use them in my 6.5 to single feed.

The mags might be Accurate Mag. My 223 AICS by Accurate Mag are like that. Never did try to modify them for a longer bullet.

The ones I saw in the article were plastic. I think.

AICS 223 mags are polymer.

The AICS pattern magazine Ruger uses in that rifle have an internal length of 2.6". With the Ruger 3 lug bolt, they feed 223 better than any bolt gun I've handled.

I bought one of these rifles, discarded the factory barrel without firing a shot, and replaced it with a 26" 1:7 Heavy Palma Bartlein.

I load 75 ELDm to 2.525" and 3030 fps. The ballistics are surprising. Barrel life should be great and ammo components are cheap.
