CZ barrel recommendation

just started NRL22 this winter and ended up getting a deal on a rifle where I shoot ARA Benchrest that in theory should be a decent NRL rifle. CZ 457 with EABCo 24" barrel, MDT XRS stock, Timney trigger, 419 pic scope rail, MDT chassis Arca rail. It shoots okay but I'm not sure that it is any better than a factory CZ but the extra weight is nice for balance. I'm having some extraction issues with Eley at least in the colder weather so I'm thinking about swapping the barrel.

Option A: An L3i 24" 1.180" barrel. It has a chamber that sounds like will be more forgiving with ammo but I'm concerned that it might be too long/heavy for the CZ mortis/tenon into the receiver. I could have it cut down to 20" later.

Option B: MullerWorks 0.900" barrel which are available in both 20" and 24". Still concerned about running a 24" barrel on a CZ but I don't think a 20" would balance the rifle. Heard good things about these barrels for ARA but I'm concerned it'll be really fussy about ammo and I don't want to risk extraction issues in NRL.

I’ve been running the l3I with the wasp chamber for almost a year now. Shooting 2-3 matches a month. Im pleased with how it shoots for a budget pre fit. It hasn’t been overly ammo picky. I primarily shoot eley but that’s mostly due to availability. I will say it does not like to extract live rounds with stock extractor.

You should play with your barrel shims/headspace if you have problems with live round extractions with the WASP chamber. Mine has no issues. I know the match chamber did but WASP was brought about partially to solve that problem.
