US Palm launched their Storm Series CAT 4 rifles at SHOT Show 2026, marking a significant shift for a company built on affordable AK accessories and magazines. The Storm lineup brings two AR-15 models designed to compete directly with established brands like Daniel Defense, with the CAT 4 representing their premium offering packed with features typically found on much more expensive rifles.
The Storm Series includes two models: the CAT3 baseline rifle and the higher-end CAT4. Both guns share core specifications: 5.56 NATO, direct impingement, 16-inch chrome moly barrels, and 7075 T-6 aluminum receivers. US Palm tops both models with their Hurricane muzzle device, a helical design that's both functional and distinctive looking. The handguards feature full-length Picatinny rails and MLOK compatibility for mounting accessories.
US Palm's marketing emphasizes durability and reliability with their "WEATHER ANY STORM" tagline. Based on early impressions from the show floor, they've delivered rifles that cycle reliably and feel very well-made.
US Palm Storm CAT4 Specifications:
- Chambering: 5.56 NATO
- Barrel: 16" chrome moly
- Muzzle Device: Hurricane Brake
- Gas system: Mid-length
- Receivers: 7075 T-6 aluminum
- Handguard: Seven-sided MLOK with angled muzzle cut, full-length Picatinny
- Controls: Fully ambi (safety, mag release, bolt catch)
- Stock: Magpul DT adjustable
- Trigger: Curved standard AR
- Additional features: Forward assist, flared magwell, reduced angle pistol grip
- MSRP: Not announced
The CAT4 separates itself through fully ambidextrous controls and ergonomic refinements. The safety selector, magazine release, and bolt catch all work from either side. That ambi bolt catch sits directly under the opened dust cover as a dedicated lever, making it easy to lock the bolt back with your trigger finger. The Magpul DT stock offers adjustable length of pull with additional cushioning in the buttpad.
The angled cut at the muzzle end gives it an aggressive look while the combination 7 sides of Picatinny and MLOK mounting provides flexibility for all sorts of attachments.
US Palm positioned these rifles to compete with Daniel Defense and other premium AR manufacturers. That's ambitious territory for a brand known primarily for AK magazines and grips. The CAT4's feature set suggests they're serious about that competition.
Century Arms distributes US Palm products, giving the Storm Series access to established dealer networks. That distribution advantage helps get these rifles in front of buyers who might otherwise stick with more familiar AR brands. Pricing wasn't announced at the show, which makes it difficult to evaluate whether US Palm hit their competitive target against DD.
The CAT3 serves as the entry point for shooters who want a solid AR without the premium features. Standard AR controls keep it familiar, while the Hurricane muzzle device, MLOK handguard, and chrome moly barrel provide functionality at what should be a lower price point than the CAT4.
For a company built on budget AK components, entering the crowded AR market represents significant risk. I am curious to see if buyers will give them a chance based on competitive features and pricing once those numbers become available.
