RimX .22 LR Barreled Action
Our RimX 22LR Barreled Actions ship with 30MOA rails and Tactical bolt knobs – if you require something different please leave it in your order comments and we will attempt to comply.
- Note [ 12/4/2020 ] Often our stock of 22LR Barreled Actions are limited. When this happens, we mark our barreled actions as “In-Stock” so we can allow customers to order and we can cap the # to the inbound quantity. Often these may not be actually on our shelf, but will be delivered in the near future. Please keep this in mind when ordering, and call us if you have any questions or concerns in this regard.

The RimX 22LR Barreled action from Zermatt Arms (previously known as Bighorn Arms) is finally here! Currently available only in Right Hand (RH) configuration – available in LH in the future.
The barrel’s muzzle is threaded 1/2×28 unless otherwise requested – RimX Barrel Thread Protectors are available here.
A top of the line rimfire action from the makers of the legendary TL3 actions, the RimX offers features and pricing not matched by the competition. This is a phenomenal action to base your 22LR trainer rifle for shooting the National Rifle League 22 matches and for practice for long range field competitions.
Rimfire rifles have never been this close to their centerfire counterparts. Thanks to a Remington 700 footprint, all the stocks, chassis, and triggers you use with your TL3 or similar actions will also be compatible with the RimX. The integral recoil lug and pinned rail work together to ensure the same rugged construction you’ve come to expect from a match-quality rifle. The receiver and the body of the bolt are nitrided, while the bolt heads are DLC coated to provide the smoothest feel.
Speaking of bolt heads, the RimX 22LR Barreled Action is available with 3 different interchangeable options to cover all popular rimfire cartridges! Currently they will ship with 22LR/17 Mach 2 bolt heads, with separate heads for 17 HMR/22 Magnum and 17 WSM available at a later date (and by request). A tool-less bayonet style fire control group means that changing between cartridges will be easier than ever before. Better yet, a non-protruding extraction system means that barrel breech faces no longer require timed extractor relief cuts. Flat breech faces, similar to centerfire rifles, combined with strict tolerances mean pre-fit barrels will be easily produced for the RimX without gunsmith’s requiring the action for their own measurements.
The RimX action is also available in 28 different rail and bolt knob combinations, allowing for customization to perfectly match your individual preferences. The pinned rails are available in 0, 20, 30, and 40 MOA inclines while bolt knobs may be picked from the tactical, teardrop, competition, helical diamond, spiral, diamond, or diamond extended offerings.
The RimX 22LR Barreled Action includes (1) magazine designed in tandem with the action to maximize the ease of loading and reliability of feeding. Machined from 7075 aluminum and hard-coat anodized, this magazine will stand up to the test of time. It includes an integrated feed ramp for the smoothest possible bolt cycle, along with a follower that has finger holds to make loading quick and easy. As a final touch, every magazine is height adjustable to really fine tune and perfect the feeding cycles.
Finally, the RimX may be ordered as either a standalone action with one magazine or as a complete barreled action with a magazine.
Both the Benchmark and Bartlein barrels are chambered using an ELEY EPS Match reamer. This reamer optimizes smooth feeding for round nosed .22LR rounds like the ones in the Lapua family of cartridges (Center X, Midas+, SK standard match etc).
Our barrels are currently only available when purchased in conjunction with our RimX actions.

Changing your Barrel
A word about action wrenches. If you are like me, one of the draws of Zermatt Arms actions is that you can easily spin on you own barrels with just a barrel vice and action wrench. The standard Zermatt Arms action wrench for the TL3 Action will work in the RimX action, as do standard Remington700 Action wrenches – no special action wrench is required.
