What Is the Faxon FF-22 Receiver Kit?
The Faxon FF-22 Receiver Kit is a billet-machined aftermarket receiver for the Ruger® 10/22® semi-automatic rimfire rifle. The receiver is CNC-machined from a solid billet of 6061-T6 aluminum and finished with a black hardcoat anodize. It is a serialized firearm and must be shipped to a Federal Firearms Licensee (FFL).
The FF-22 is designed as a direct drop-in replacement for the factory Ruger 10/22 receiver (non-takedown models). It is compatible with all Ruger 10/22 OEM non-takedown components — bolt assemblies, triggers, trigger groups, charging handles, barrel assemblies, and stocks — as well as all Faxon Rimfire barrels for 10/22 and most aftermarket chassis systems, triggers, and internals built to the non-takedown 10/22 specification.
The kit includes the receiver, a chromoly steel V-block with V-block screws (which secure the barrel to the receiver), and a rubber bolt buffer. To complete a rifle build, you will also need a barrel, bolt assembly, trigger group, charging handle, and stock or chassis. Faxon offers the FF-22 Bolt Assembly and a full line of Rimfire Plinker and Match Series barrels designed to pair with this receiver.
What’s Included
FF-22 Receiver
6061-T6 billet aluminum, CNC-machined, black hardcoat anodize. Integrated 0-MOA Picatinny rail with extended length. Serialized.
V-Block & Screws
Chromoly steel V-block with two #12-24 screws. Secures the barrel to the receiver in the standard 10/22 V-block configuration.
Rubber Bolt Buffer
Cushions bolt cycling for reduced wear and quieter operation. Installs in the rear of the receiver.
What You Still Need to Complete a Rifle Build
The FF-22 Receiver Kit is not a complete rifle. To build a functioning .22 LR rifle, you will also need a barrel, bolt assembly, trigger group (including hammer, sear, springs, pins, and trigger), charging handle, and a stock or chassis. Ruger® 10/22 OEM parts or compatible aftermarket components from Faxon and other manufacturers will work.

Engineering & Manufacturing
The FF-22 receiver is CNC-machined from a solid billet of 6061-T6 aluminum across three manufacturing operations. OP-10 saws the bar stock to rough dimensions (1.500" × 3.000" × 7.250"). OP-20 machines the Picatinny rail, outer profile, barrel channel, V-block screw holes, and cross-pin holes. OP-30 machines all interior features including the bolt raceway, ejection port, trigger group pocket, and engraving.
Critical dimensions are verified throughout production per Faxon’s MBR (Manufacturing Build Record) inspection protocol. The barrel channel bore (∅.687" +.002"/-.000"), front ring OD (∅.940" ±.005"), receiver width (.833" ±.002"), and cross-pin holes (∅.250" ±.005") are checked with Go/No-Go pin gages and micrometers at a frequency of 1-in-10 parts. V-block screw threads (2× #12-24) are verified 100% with Go/No-Go thread plugs. Interior features are measured with Sylvac instruments, height gages, and depth gages. A CMM dimensional verification runs once per shift, and a functional check with a master gage is performed on 1-in-10 parts (with 100% verification on critical assemblies).
The receiver is engraved on the left side with “FAXON FIREARMS / FAIRFIELD, OH, USA / FF-22 / 22LR” plus a unique serial number. Engraving depth is .010" ±.005" per ATF requirements. The finished receiver is hardcoat anodized to a 125 surface finish for durability and corrosion resistance.
Compatibility
Barrels
All Faxon Rimfire barrels for 10/22 (Plinker Series and Match Series) and most aftermarket 10/22 barrels designed for the OEM non-takedown V-block system. Barrel channel bore is ∅.687".
Bolt Assemblies
Compatible with Ruger® 10/22 OEM bolt assemblies and aftermarket bolts including the Faxon FF-22 Bolt Assembly (QPQ finish).

Stocks & Chassis
Compatible with most aftermarket 10/22 stocks and chassis designed for the standard (non-takedown) Ruger 10/22 receiver. Not compatible with Ruger 10/22 Takedown models.
Barrel Installation & Thermal Fit
The FF-22 receiver’s barrel channel is machined to a tight tolerance (∅.687" +.002"/-.000") to prevent barrel droop — a common accuracy issue on the 10/22 platform where a loose barrel-to-receiver fit allows the barrel to sag under its own weight. Because of this intentionally tight fit, some barrels may require a thermal fit for installation.
To thermal fit a barrel, heat the front ring of the receiver with a heat gun or hair dryer for 30–60 seconds. The aluminum receiver will expand slightly, allowing the barrel shank to slide in. Once the receiver cools, it contracts around the barrel for a secure, concentric fit that eliminates play between the barrel and receiver. This is normal and by design — it is the same technique used on many precision 10/22 builds.
If you are installing a Faxon Rimfire barrel, the barrel shank is ground to match the FF-22’s barrel channel. Aftermarket barrels from other manufacturers may vary slightly in shank diameter; a thermal fit will accommodate minor variations. The V-block and screws then lock the barrel in position.

Frequently Asked Questions
What is the Faxon FF-22 Receiver Kit?
The Faxon FF-22 is a billet-machined 6061-T6 aluminum receiver for the Ruger 10/22 rimfire rifle platform. The kit includes the receiver with an integrated 0-MOA Picatinny rail, a chromoly steel V-block with screws, and a rubber bolt buffer. It is a serialized firearm and must be shipped to an FFL dealer.
Is the FF-22 compatible with my Ruger 10/22?
The FF-22 is compatible with all Ruger 10/22 non-takedown OEM components including bolt assemblies, trigger groups, barrels, charging handles, and stocks. It is not compatible with Ruger 10/22 Takedown models. It is also compatible with most aftermarket 10/22 components designed for the standard non-takedown receiver.
What do I need to complete a rifle build with the FF-22?
You need a .22 LR barrel (Faxon Rimfire or compatible 10/22 barrel), a bolt assembly (Faxon FF-22 Bolt or Ruger OEM), a complete trigger group (with hammer, sear, springs, and pins), a charging handle, and a stock or chassis. Ruger OEM parts or compatible aftermarket components will work.
Why does the FF-22 need to ship to an FFL?
Under federal law, the receiver of a firearm is the serialized, regulated component. Because the FF-22 receiver is serialized and legally classified as a firearm, it must be shipped to a licensed Federal Firearms Licensee (FFL) dealer for transfer. You will need to provide your FFL dealer’s information during checkout and complete the required paperwork (Form 4473) at the FFL to take possession.
What is the difference between billet and cast receivers?
A billet receiver is CNC-machined from a solid block of aluminum, producing tighter tolerances and more consistent dimensions than a cast receiver. The Faxon FF-22 is machined from 6061-T6 aluminum billet with critical features inspected by Go/No-Go gages and CMM. The factory Ruger 10/22 receiver has historically used investment casting or stamped construction, depending on the model and production era.
What barrels work with the FF-22?
The FF-22 accepts all Faxon Rimfire barrels for 10/22 (Plinker Series and Match Series), Ruger OEM 10/22 barrels, and most aftermarket 10/22 barrels that use the standard V-block barrel attachment system. The barrel channel is bored to .687 inches. Faxon offers barrels in Flame Fluted, Straight Fluted, Pencil, and Bull profiles from 10 to 18 inches.
Do I need to thermal fit the barrel into the FF-22 receiver?
You may need to. The FF-22’s barrel channel is machined to a tight tolerance (.687 inches +.002/-.000) to prevent barrel droop, which is a common accuracy issue on the 10/22 platform. If the barrel does not slide in by hand, heat the front ring of the receiver with a heat gun or hair dryer for 30 to 60 seconds. The aluminum will expand enough to accept the barrel shank. Once it cools, the receiver contracts around the barrel for a tight, concentric fit. This is normal and by design.
Does the FF-22 include a scope rail?
Yes. The FF-22 has an integrated 0-MOA Picatinny rail machined directly into the top of the receiver. The rail is longer than the factory 10/22 rail, providing more mounting options for scopes, red dots, and other optics. No separate scope base or adapter is needed.
Does the FF-22 work with 10/22 Takedown models?
No. The FF-22 is compatible with standard (non-takedown) 10/22 components only. It does not support the barrel-to-receiver locking mechanism used in Ruger 10/22 Takedown models.
Can I use the FF-22 as a drop-in replacement for my factory 10/22 receiver?
Yes. If you have a non-takedown Ruger 10/22, you can transfer your bolt, trigger group, barrel, charging handle, and stock directly onto the FF-22 receiver. The V-block and bolt buffer are included. This is a common upgrade for shooters who want tighter tolerances and an integrated Picatinny rail while keeping their existing components.
Can I suppress my FF-22 build?
Yes. Every Faxon Rimfire barrel for the 10/22 platform ships threaded 1/2x28, so no adapter or additional threading is needed. The Faxon Twenty-Toucan® is a modular .22 LR suppressor with six tunable baffles in 17-4 PH stainless steel. It is full-auto rated for .22 LR, .22 Mag, .17 HMR, and 5.7x28mm, and measured hearing-safe at 131.95 dB at the muzzle during the 2025 Silencer Summit. A suppressor is an NFA item — you will need to submit an eForm 4 through your dealer. The $200 NFA tax stamp fee has been eliminated.
Where is the FF-22 receiver made?
The FF-22 receiver is designed and manufactured by Faxon Firearms at their facility in Fairfield, Ohio, USA. Faxon is an ISO 9001:2015 certified manufacturer and a federally licensed firearms manufacturer (FFL). All FF-22 receivers are covered by Faxon’s Lifetime Guarantee.

Good choice to build from scratch
Used for a build, proceeded to win a medal at CMP nationals

Excellent receiver
Purchased this receiver and I've gotta say i wasn't expecting it to look or feel as good as it does in the hand. Excellent fitment with the barrel that I chose and was really pleased with the QC. Will be getting another if they have one for a take down project that I'd like to do. Very fast shipping and very well packaged.

FF-22 Receiver
I built a 10/22 for my wife using this receiver, the Faxon bolt and one of the Faxon bull barrels. There were some pretty big accuracy issues at first, and my first thought was the barrel. Customer service was great and got me a new barrel quickly, but I found the issue was the receiver's inlet for the barrel being too large. Not a problem, I shimmed the new barrel tenon and now it's a great little plinker. Overall I'd buy this receiver again for my next build.

Overall amazing value, I just wish they didn't skimp on the guide rod seat
Overall this is a great quality receiver and good value. Love that it comes with the integrated pic rail and includes thing like the V-Block and bolt buffer. However, I'm a little disappointed in the design on the Guide Rod Seat. Instead of doing a conical seat that 10/22 Guide Rods all use, they drilled straight down to make sort of a 1/3 circle. While this works and probably saves money, it allows the guide rod to pop out when installing the bolt if you're not careful. Just know that for the money you'll save here, you'll spend a bit of extra time installing the bolt and charging handle assembly every time you have to remove the bolt for cleaning or changing something out.

FF-22 Receiver
This receiver is really high quality. The top rail is extended over the standard 10/22 receiver. Great starting point for a build.
