SPIKE'S TACTICAL ST 15

Overview

Spike's Tactical ST-15 .22 LR - Match-Grade Rimfire AR with 16" BarrelSpike's Tactical ST-15, .22 LR, 16" Barrel - Match-Grade Accuracy in a True AR PlatformIf you want a genuinely accurate rimfire AR built by a manufacturer trusted for law enforcement-grade quality, the Spike's Tactical ST-15 in .22 LR delivers exactly that. This isn't a stripped-down plinker dressed up to look like an AR - it's a real, purpose-built rimfire rifle engineered around Spike's reputation for uncompromising component quality, giving shooters an affordable, low-recoil way to train, plink, and build serious trigger time.Match-Grade Accuracy, Purpose-Built for .22 LRAt the heart of this rifle is a 16" barrel built specifically for the .22 LR cartridge - not a repurposed centerfire barrel with a smaller chamber bored in. Spike's Tactical uses genuine match-grade chrome-moly construction with a twist rate correctly matched to rimfire ballistics, a critical detail that separates this rifle from lower-quality .22 LR AR conversions on the market. That correct twist rate translates directly into tighter groups, more consistent cycling, and significantly less fouling over the life of the barrel - details that matter to shooters who actually care about accuracy, not just novelty.The barrel is threaded, giving you the flexibility to add a suppressor for an exceptionally quiet, low-recoil shooting experience - one of the biggest reasons rimfire ARs like this one have become so popular for training, pest control, and simply enjoying extended range sessions without the noise or recoil fatigue of a centerfire rifle.Real AR Ergonomics, Dedicated Rimfire EngineeringUnlike many budget .22 LR AR platforms that rely on aftermarket conversion kits, the ST-15 uses Spike's Tactical's dedicated .22 LR bolt group, purpose-engineered for reliable rimfire cycling rather than adapted from a centerfire design. This means you get the authentic feel, weight, and manual-of-arms of a full-size AR-15 - the same controls, the same manipulation, the same muscle memory - while shooting one of the most affordable and widely available cartridges on the market.That's a genuine advantage for shooters who want to build familiarity with AR-platform controls without burning through expensive centerfire ammunition every range trip. The ST-15 lets you train trigger control, sight picture, and follow-through using low-cost .22 LR, then carry that exact same manual of arms straight over to your centerfire AR-15.Built on Spike's Trusted Receiver PlatformThe ST-15 upper is machined from 7075-T6 aluminum and finished with Mil-Spec protective coatings for long-term corrosion resistance, the same standard of construction Spike's Tactical built its reputation on supplying to law enforcement customers. This rifle is optics-ready right out of the box, giving you the flexibility to mount a red dot for fast training drills or a magnified optic for more precise range work.
