VOLQUARTSEN FIRE FLY 2 | RUGER 10/22 | SUBSONIC .22 LR
Built for Subsonic. Tuned for the 10/22.
The Volquartsen FireFly 2 VF10FY2 is a lightweight CNC-machined aluminum bolt assembly intended to help a compatible Ruger 10/22 cycle subsonic .22 LR ammunition. Instead of treating reduced-power ammunition like a conventional high-velocity load, FireFly 2 gives the rifle a purpose-built bolt and recoil system for this narrower job.
The bolt is Type III hard-anodized aluminum with a hardened steel contact insert for the hammer. It comes with Volquartsen’s round titanium firing pin, heavy-duty extractor, and precision-ground hardened A2 recoil rod. Two recoil springs are supplied, including the reduced-power spring installed in the current Pete’s Pillars configuration.
Volquartsen designed this assembly for subsonic .22 LR loads, from CCI Quiet ammunition rated around 710 fps up to loads approaching 1,050 fps. Results depend on the individual rifle and ammunition; it is not the general-purpose high-velocity bolt for every 10/22. For standard builds, the Volquartsen Competition Bolt is a separate option. Keeping your original bolt? The Volquartsen VC10FE Bolt Tune-Up Kit is a worthwhile upgrade for that conventional bolt rather than an internal parts kit for the FireFly 2.

Frequently Asked Questions
What is the Volquartsen FireFly 2 bolt designed to do?
FireFly 2 is a lightweight bolt assembly for Ruger 10/22 .22 LR rifles using subsonic ammunition. Its purpose is to provide a different cycling setup for reduced-energy ammunition, not simply a cosmetic replacement for the factory bolt.
Will the FireFly 2 cycle CCI Quiet 710 fps ammunition?
Volquartsen identifies CCI Quiet ammunition around 710 fps as part of the intended subsonic range, extending toward 1,050 fps. Actual cycling depends on the rifle, ammunition, receiver condition and other components. No particular ammunition is guaranteed to function in every rifle.
Can I use regular, high-velocity or hyper-velocity .22 LR with this bolt?
The FireFly 2 is intended for subsonic .22 LR and the manufacturer describes its design range as below approximately 1,050 fps. Do not assume standard- or high-velocity ammunition is suitable. For a broader conventional ammunition setup, consider the separately listed Volquartsen Competition Bolt and follow Volquartsen’s ammunition guidance.
What recoil springs and internal parts are included?
Volquartsen supplies two recoil springs, with the reduced-power spring installed in the product configuration described by Pete’s Pillars. The assembly also includes a hardened A2 recoil guide rod, round titanium firing pin, and heavy-duty extractor. It also uses a hardened steel contact insert to protect the aluminum bolt from hammer wear.
Does the FireFly fit a Ruger 10/22 Takedown, Charger or aftermarket receiver?
Volquartsen describes the FireFly as compatible with factory Ruger 10/22 receivers and its own compatible aftermarket receivers, but other aftermarket receivers can vary. Ruger Charger and Takedown configurations should be checked by exact receiver and barrel setup; short barrels and different configurations may affect subsonic functioning. Contact us with the exact configuration when unsure.
Will it run with or without a suppressor?
The manufacturer markets FireFly 2 for subsonic setups with or without a suppressor, but cycling depends on ammunition and the complete rifle. This bolt does not guarantee reliable function with every subsonic load or accessory combination.
Which barrels and triggers make sense with this bolt?
For barrels, compare Green Mountain stainless fluted, Shaw stainless, Volquartsen Ultralite or TandemKross Spitfire. For triggers, consider TandemKross Manticore, Volquartsen TG2000, Timney two-stage. KIDD also offers complete single-stage and two-stage trigger options. Barrel length, suppressor use and ammunition all affect subsonic performance; browse all Ruger 10/22 parts and upgrades for more options.
