Breakthrough Clean Technologies® Square Cotton Patches — .17 Caliber / .177 Airguns | 0.75" x 0.75", 375-Pack | BT-CP-S-3/4-375 | BTCPS34375 | UPC 854325008162
Keep tiny bores laser-accurate with Breakthrough Clean Technologies Square Cotton Patches sized specifically for .17 caliber rimfire and .177 airguns. Cut to 0.75" x 0.75" (3/4") and packed 375 per box, these tight-weave, low-lint cotton patches deliver reliable bore contact, excellent solvent uptake, and smooth oil application—so you can clean faster, protect rifling, and get back to stacking pellets and groups.
Why These .17/.177 Patches Are Better
Perfect fit for small bores: Optimized 3/4" square provides confident engagement in .17 HMR/HM2 and .177 air rifle/pistol barrels when paired with the appropriate jag or patch loop.
High absorbency, low lint: Premium cotton holds solvent, CLP, and silicone oils while minimizing fiber shed for a bright, uniform finish.
Uniform thickness & cut: Consistent density means predictable push resistance and thorough 360° contact—pass after pass.
Efficient cleaning = fewer passes: The square profile wipes lands and grooves effectively, speeding up routine maintenance and match prep.
Bench-friendly value: 375 patches keep your kit stocked for months of practice sessions and range days.
Ideal For
.177 air rifles & pistols: PCP, spring-piston, and gas-ram platforms
.17 caliber rimfire: .17 HMR / .17 HM2 rifles for precision and varmint work
Competition & training: Fast, repeatable cleaning between strings
Long-term storage: Even, light oil film to inhibit rust and moisture damage

Faster, Cleaner Results for Small Bores
Small bores foul quickly and show accuracy loss sooner than larger calibers. These square patches deliver dependable rifling contact to lift powder/carbon residue, pellet lube, and lead while transferring solvent and protectant evenly. The result: shorter cleaning cycles, better consistency, and longer barrel life.
How to Use (Best Practices)
Select the right tip: Pair with a .17/.177-specific jag or loop. For delicate airgun barrels, a pull-through cable is often preferred.
Solvent pass: Lightly saturate a patch with your chosen bore solvent (use airgun-safe formulas for PCP/springers); push one direction through the bore.
Agitate (optional): For stubborn deposits, use a caliber-matched nylon/bronze brush, then follow with fresh solvent patches.
Dry passes: Run clean, dry patches until they emerge light gray to clean.
Protect: Finish with a very light oil patch. Airgun tip: Use non-dieseling airgun oils; avoid petroleum-heavy oils in springers to prevent detonation.
Fit Tip: If a patch feels too tight with a specific jag, switch to a loop-style holder or trim a corner. Bore and jag tolerances vary by brand and platform.
Airgun-Specific Tips
Crown care matters: Always push patches straight through; avoid reversing in the bore.
PCP vs. springer oils: Use silicone chamber oil or airgun-rated protectants for PCPs; keep spring-piston compression chambers free of petroleum oils.
Moderator shrouds: Remove baffles or use a guide when needed to keep fabric from snagging.
