Don't.
The RPRf is one of the most disappointing firearms to hit the market in my memory. The original centerfire RPR provided competition-level accuracy at a bargain price. I heard good things about the RPRf from people involved with its development. So I bought one of the early ones for my nephew, who was competing in one or two centerfire disciplines.
What a disappointment. Flaky accuracy with every flavor of match ammo I tried in it. Flimsy construction. Reports of feeding issues abounded.
Much better to hold out for a CZ 457 or similar.
The RPRf may work just fine for people who want to buy bucket'a'bullets ammo and shoot tin cans. I see few if any of them at rimfire matches, and when I do see them their owners aren't on the leaderboards.
Also, be aware that competition-grade .22LR ammo runs $.20-25 a round, with decent practice ammo around $.15 per round. I bought a case of CCI SV pre-pandemic at less than $.06 per round; it's ok for positional practice but at I won't use it in matches... one can occasionally find amazingly accurate lots of cheap ammo; those people should buy PowerBall tickets at every opportunity.
With all that said - I find I enjoy PRS-style rimfire matches more than centerfire ones. That's just me.
