Purpose-Built Recoil Spring for CMMG 22ARC .22 LR Conversions
This isn’t a generic spring—it’s specifically designed for the CMMG 22ARC .22 LR AR-15 conversion platform:
Calibrated for .22 Long Rifle cycling in CMMG’s 22LR/22ARC conversion bolts and dedicated uppers.
Helps maintain proper timing, bolt movement, and return-to-battery with lightweight rimfire cartridges.
Ideal as a replacement for a worn or weakened spring, or as a spare in your parts kit for high-round-count shooters.
Using the correct factory-spec recoil spring is essential for reducing failures to feed, failures to eject, and short-stroking in .22 LR AR builds.
Simple, Effective Design – Drop-In Installation
The CMMG 22ARC Recoil Spring 22BA4BC features a straightforward, coiled-spring design that focuses on function over frills:
Drop-in part – installs easily in the 22ARC / 22LR AR conversion assembly with no gunsmithing required.
No special tools needed—perfect for home builders and everyday shooters.
Designed as a direct OEM replacement, ensuring proper fit with CMMG 22ARC components.
If your .22 AR starts to feel sluggish or inconsistent after thousands of rounds, swapping in a fresh 22ARC recoil spring is one of the fastest troubleshooting steps you can take.
Built for Durability – Thousands of Rounds of Rimfire
Even though it’s a small part, the CMMG 22ARC Recoil Spring is built for the demands of high-volume .22 LR shooting:
High-quality spring steel construction balances flexibility and strength.
Designed to withstand thousands of rounds of low-pressure rimfire use when maintained with normal cleaning and light lubrication.
Silver finish makes it easy to visually inspect for dirt, wear, or damage during routine maintenance.
For serious trainers and plinkers alike, keeping a fresh recoil spring on hand helps avoid unexpected downtime on the range.
Improve Reliability & Reduce Malfunctions
Shooters running CMMG 22ARC conversions often choose this spring to cure annoying cycling issues:
Helps smooth out bolt travel, improving feeding and ejection with a wide range of .22 LR loads.
Can significantly reduce stovepipes, failures to eject, and short strokes that sometimes occur when a recoil spring wears out or when using inconsistent bulk ammo.
A low-cost part that often delivers a big improvement in overall reliability and shooting experience.
If your .22 AR used to run well and suddenly becomes finicky, a new recoil spring is one of the smartest and most affordable places to start.
