Who owns a CZ MTR,or an RAP?

[Harpoon1]

I don’t get it.My RAP works fine with ASC factory 10 rd mags .I never had to cut off any coils.Not that it would matter much.Sooner or later I’m going to get a custom barrel and have the bolt reworked.Only original part will be the receiver.

Have you tried shorter bullets/rounds? Or, have all of your rounds been with 123 grn bullets and close to 2.260”?
