GREEN MOUNTAIN RUGER 10/22 28″ STAINLESS BULL BARREL
Twenty-Eight Inches. A 10/22 Built to Stand Apart.
The Green Mountain 901949 brings an unusual 28″ barrel length to the Ruger 10/22 platform. This .920″ stainless bull barrel is a deliberate choice for shooters who want an extra-long, heavy-profile .22 LR build—not another conventional 16–20″ 10/22. The length is the point: distinctive proportions and a dedicated, deliberate range-rifle character.
Most 10/22 replacement-barrel decisions involve modest differences in length and contour. The 901949 stretches to a full 28″—eight inches longer than a 20″ barrel and ten inches longer than an 18″ one. That makes the rifle visibly different and changes how it handles. It is a natural candidate for a bench-supported or slower-paced range project, rather than a rifle chosen for minimal overall length. Use it for: dedicated bench and target-range setups, extra-long 10/22 projects, and shooters who specifically want a substantial stainless bull barrel.
The Length Is the Feature.
An extra-long barrel is not a shortcut to smaller groups or guaranteed higher velocity. What the 901949 offers is the opportunity to build a 28″ Ruger 10/22 around a traditional full-diameter steel barrel. Green Mountain specifications currently shown on our listing call out 416 stainless steel, .920″ bull contour, 1:16 twist, a Bentz .22 LR chamber, button rifling, stress relief and air gauging. If you are planning to carry the rifle long distances or compete in a weight-conscious discipline, be realistic about the size and forward weight. For a rifle you intend to enjoy from a supported firing position, the long profile is precisely what makes this one interesting. We also carry rifle scopes and scope mounting options to finish an optic-based setup.

Pair It With: Small Hardware That Belongs With a Barrel.
Keep the little pieces where they belong. If the rifle is already apart, these three compact accessories are practical additions—but they should not overshadow the 28″ barrel or the larger build decisions.

A 28″ .920″ barrel calls for the right stock or chassis. Consider the MDT Field Stock, KRG Bravo and Oryx for a bench-oriented setup, and check the barrel-channel opening against the .920″ contour. The length of the barrel extends well beyond a typical forend; confirm overall balance and handling for your intended use.

With the 28″ barrel and stock settled, a quality trigger and bolt assembly are the next substantial pieces to consider. The TandemKross Manticore offers a complete assembly with additional controls; the Volquartsen TG2000 is another proven trigger-focused choice. KIDD single-stage and two-stage triggers are worth comparing by name, but we reserve the featured product cards for other options in our catalog. Add a bipod or optic to suit the supported shooting position you have in mind.

Each serves a different priority; no shorter-barrel alternative is pretending to be the same thing as this 28″ model.

Frequently Asked Questions
The 28″ length, .920″ channel fit, chamber, and choices that complete the rifle.
Why would I choose a 28″ barrel for a Ruger 10/22?
Because you specifically want the look and handling of an extra-long .22 LR barrel. The 901949 is eight inches longer than a 20″ barrel, making it an unusual choice for a bench-focused or dedicated range rifle rather than a compact field setup.
Does the 28″ length automatically improve accuracy or velocity?
No. Barrel length by itself does not guarantee smaller groups, increased velocity or better reliability. Ammunition, barrel quality, chamber, rifle setup and the shooter all matter. Choose the 901949 for its extra-long configuration, not a promised performance gain.
Will the .920″ bull barrel fit my 10/22 stock?
You need a barrel channel that will clear the .920″ bull contour. Many factory sporter-taper stocks will not have adequate clearance. Check the exact channel and the overall balance of the finished rifle before choosing a stock or chassis.
Does it fit every Ruger 10/22, including Takedown models?
It is listed for Ruger 10/22-pattern .22 LR rifles. Do not assume compatibility with Takedown or other nonstandard receiver/barrel arrangements. Confirm the exact inlet and barrel mounting configuration for your rifle before ordering.
What chamber and twist does the 901949 use?
The current Pete’s Pillars listing specifies a Bentz .22 LR chamber and 1:16 twist, along with 416 stainless steel construction. These details are taken from the current listing; the manufacturer’s exact 901949 datasheet was not independently available for verification. Confirm ammunition suitability with Green Mountain.
Is this 28″ barrel fluted or muzzle threaded?
Our existing listing text mentions fluting, but the exact exterior configuration and muzzle threading have not been independently confirmed for MPN 901949. Do not assume threaded muzzle hardware or a particular exterior finish. Verify the selected barrel configuration before ordering.
What upgrades make sense alongside a 28″ barrel?
Start with a compatible stock, a complete trigger assembly and appropriate optics. For supporting hardware, see our Viton buffer and stainless pin kit and V-block screws. A Volquartsen Competition Bolt is a bigger next step.
