Description

The FAB Defense FXM4PR1022B takes a bone-stock Ruger 10/22 and gives it a full M4-style makeover. You get a collapsible buttstock, a left-side folding hinge, an ergonomic pistol grip with finger grooves, and enough rail space to hang whatever optics, lights, or lasers you like. It manages to blend an old-school bench-rest feel with a genuinely modern tactical layout, which is a big part of why this chassis has such a following among 10/22 owners looking to freshen up a rifle that's been sitting in the safe for years.

What the FXM4PR1022B Brings to Your 10/22

The chassis carries 1913 MIL-STD Picatinny side and lower rails, so mounting accessories is straightforward and secure. The buttstock adjusts through five length positions, and the length of pull runs from roughly 13.11 to 15.94 inches, which covers most body types and lets you dial in a comfortable fit. A built-in adjustable cheek rest with five height settings helps you get a consistent cheek weld behind glass, and quick-detach sling swivel sockets on both sides mean you can run a sling however you prefer.

Fit, Feel, and Folding

The stock body is molded from fiberglass reinforced polymer, so it stays light without feeling cheap or hollow. It fits both standard and bull-barreled Ruger 10/22 rifles, and the left-side folding buttstock collapses the whole rifle down for compact storage and easier transport in a pack or case. The ergonomic grip shape is designed to cut down on wrist fatigue during longer range sessions.

Getting It Installed

This is a true drop-in conversion, no gunsmithing required. Most owners have their rifle swapped over in a few minutes using basic hand tools, and the hardware you need comes in the box. Reviewers consistently point out how tight everything locks up once installed, with minimal play or rattle across the grip, forend, and buttstock. It's a solid pick if you want to modernize the look and handling of your 10/22 without touching the core controls or fire-control group.

Frequently Asked Questions

Will the FXM4PR1022B fit my bull-barrel 10/22?

Yes. This conversion kit is built to fit both standard and bull-barreled Ruger 10/22 rifles. The forend has the clearance to handle the heavier barrel profile, so you don't need a separate version for a bull barrel setup.

Do I need a gunsmith to install this stock?

No. The FAB Defense M4 kit is a genuine drop-in conversion that you can do at home with basic hand tools. Most people have their rifle swapped over in just a few minutes, and the hardware you need is included in the box.

Which way does the buttstock fold?

The buttstock folds to the left side by default, which keeps the rifle compact for storage and transport. You can still load, charge, and fire once the stock is unfolded and locked into place.

Can I mount an optic and other accessories on it?

Absolutely. The chassis includes 1913 MIL-STD Picatinny side and lower rails for lights, lasers, and grips. The adjustable cheek rest with five height positions also helps you line up a proper cheek weld once you add an optic over the receiver.
