POSITION7 CZ 457 BILLET ALUMINUM SHORTY MAGAZINE | .22 LR | 10 ROUND
Ten Rounds, Nothing Hanging Down.
The Position7 CZ457-MAG-10RD-SHORTY is a 10-round .22 LR magazine CNC-machined from 7075 billet aluminum, built short so it sits close to the stock instead of hanging below it. You get billet durability and a crisp, repeatable seat without a magazine that gets in the way of a bag, a bench or a tight prone position.
Not every rifle needs a stage magazine. A lot of rimfire shooting is prone off a bag, off a bench, or walking a fenceline, and in all three a tall magazine is just something to catch. The Shorty keeps the billet aluminum body and the precise fit of the Position7 line and trims it down to 10 rounds, so the bottom of the rifle stays clean. Steel small-head Torx fasteners and a custom spring keep it serviceable instead of sealed. Use it for: prone and bench work, NRL22 and rimfire steel where 10 is enough, small game, .22 trainers and any CZ 455 or 457 you carry more than you shoot off a tripod.
Short on Purpose.
A factory polymer magazine flexes a little every time it seats, and the taller it is the more leverage it has to move. Machining the body from 7075 billet aluminum takes that flex out, and keeping it to 10 rounds keeps the magazine tucked up near the stock line. The result is a magazine that goes in the same way every time and stays out of the way of whatever the rifle is resting on. It comes apart with steel small-head Torx fasteners for cleaning or a spring swap, and it was designed by Roman Konečný, the 2025 IPRF PR22 Senior Division World Champion, as part of the same line as the 13-round.
Read This Before You Load It.
An aluminum magazine is harder than the factory CZ 457 polymer magwell it drops into. Position7 recommends running an aluminum magwell with aluminum magazines, because repeated seating against polymer raises the risk of cracking the factory well over time. If your rifle is still on the original polymer magwell, plan on an aluminum one as part of this upgrade. We make the PP457MW aluminum magazine well, and Position7 offers a full RH billet magwell kit that pairs with this magazine. Position7 does not independently confirm L3i magwell compatibility, so check that pairing before you order.
Our Take
Give It an Aluminum Well: PP457MW
We've spent more than six years building, tuning and supporting CZ rimfire rifles, and the factory polymer magwell is one of the first things we replace on a match gun. The PP457MW is our machined aluminum replacement, and it's the part we'd put under this magazine. Our parts fit most CZ 455 and 457 rifles. We machine to very tight tolerances, so every now and then a production rifle with factory tolerance stack-up falls a little outside that range.

Frequently Asked Questions
Fitment, magwells, capacity and building out your CZ 457.
Will it fit my rifle?
It's built for compatible CZ 455 and CZ 457 .22 LR configurations, and Position7 reports tested fit on the LRP, American, Varmint and MTR. Fit can vary with your magwell, magazine catch and chassis, so check those if you're running an aftermarket setup.
Do I need an aluminum magwell?
It isn't strictly required, but it's strongly recommended. Seating an aluminum magazine against the factory polymer magwell over and over raises the risk of cracking the polymer. Use our PP457MW aluminum magazine well or the Position7 magwell kit.
Does it work in .17 HMR or .22 WMR?
No. This magazine is .22 LR only. Magnum rimfire cartridges need a different magazine.
Why go billet instead of the factory polymer magazine?
Two reasons. A machined aluminum body doesn't flex as it seats, so the magazine locks up the same way every time and feeds more consistently. And it comes apart with Torx fasteners, so you can clean it or change the spring instead of replacing the whole magazine.
Shorty or the 13-round?
Pick by how you shoot. The Shorty stays close to the stock, so it's the one for prone, bench and carrying. The 13-round gives you 12+1 for a stage and a reduced-curvature body shaped for deep chassis cavities, at the cost of sitting lower. Both are the same billet aluminum line, so plenty of shooters keep one of each.
Position7 or L3i billet magazines, which is better?
We only carry parts we trust, can stand behind and know are built with quality, so you're in good hands either way. L3i builds excellent billet magazines and magwells, and plenty of match shooters run them. Position7's advantage here is the machining and the short-body profile, designed by a working PR22 world champion who shoots the platform.
Does Pete's Pillars sell more than magazines?
Yes. We machine our own CZ 457 firing pins, cocking indicators, magazine releases, bolt knobs, rails, match barrels and pillar bedding, and we carry chassis from MDT, XLR and Grey Birch, barrels from Lilja and L3i, optics, bipods and reloading gear like the Area 419 ZERO press.
