L3I CZ 457 24″ DROP-IN MATCH BARREL – 1.180″ HEAVY CONTOUR
A Match-Grade Heavy Barrel That Drops Right In.
The L3i CZ 457 Drop-In Match Barrel is a 24″, 1.180″ straight bull contour in 416R stainless, cut with L3i's proprietary Wasp Match Chamber and a 1:16 twist. Lead-lapped, stress-relieved and finished with an 11° target crown, it installs with the included headspace shim kit. Made in the USA.
The barrel is where a CZ 457 competition build starts to separate itself. L3i's drop-in design gives you a true match chamber and a heavy, stable contour without sending the rifle to a gunsmith. The full 1.180″ profile soaks up heat and holds steady on barricades, while the lapped bore and target crown deliver the consistency serious rimfire shooters chase. Use it for: PRS Rimfire, NRL22, precision target shooting and benchrest-style .22 LR builds.
Match Chamber, Drop-In Fit.
L3i's Wasp Match Chamber is cut for match .22 LR ammunition, and the precision headspace shim kit lets you set headspace correctly on your own action at the bench. The unthreaded muzzle carries an 11° target crown that protects accuracy and keeps the profile clean.
Check Your Barrel Channel.
A 1.180″ straight contour needs room. Many factory sporter stocks and some narrow varmint stocks won't clear it, so confirm your stock's barrel channel before ordering. Building a dedicated match rifle? Competition chassis like the MDT ACC Elite CZ 457, ACC Premier Gen2 and LSS Gen3 Competitor are popular homes for heavy-contour rimfire barrels. Confirm clearance for your chosen chassis.

Which rifles does it fit?

Is it truly drop-in?
Yes. It installs on your CZ action using the included precision headspace shim kit to set headspace correctly.
Will it fit my factory stock?

What is the Wasp Match Chamber?
It's L3i's proprietary match chamber for .22 LR, cut for consistent performance with match-grade rimfire ammunition.

Both are 24″, 1.180″ straight contours with 1:16 twist. The Lilja uses a three-groove, hand-lapped bore and the Lilja 3 chamber. The L3i uses 416R stainless and the Wasp Match Chamber. Both are excellent match choices.
