FAQ
Where can I buy Proof Research barrels online?
Kansas Gunshop (kansas-gunshop.com) stocks authentic Proof Research barrels with same-day shipping from Wichita, KS.
Does this fit CZ 457 American models?
Yes – compatible with all CZ 455/457 variants except the “Scout” model with shorter action.
What ammo works best?
Match-grade .22 LR like Eley Tenex or Lapua Center-X. Bulk ammo won’t showcase the barrel’s full potential.
Is the carbon fiber durable?
Proof Research barrels undergo MIL-SPEC testing. The carbon fiber wrap is impact-resistant and won’t warp like thin steel barrels.
Can I install this myself?
Not recommended – barrel fitting requires headspace gauges and specialized tools. We suggest using a qualified gunsmith.
Does it come with a warranty?
Proof Research offers a lifetime warranty against defects to the original purchaser.
How much accuracy improvement?
With quality ammo, most shooters see 30-50% tighter groups versus factory barrels, especially after 50+ rounds when warmed up.
