Steiner Optics, the leader in high-performance sighting systems for military, law enforcement, and armed professionals, expands its pistol optics lineup with the Steiner MPS-C. Designed for today’s concealed carry users and compact-frame pistols, the MPS-C delivers the same battle-proven pedigree as the original MPS—now in a more compact RMSc footprint optimized for everyday defense.
Purpose-engineered for the demanding environments faced by law enforcement officers and protection-minded citizens alike, the MPS-C retains the same trusted internal architecture of the original optic. A fully sealed, enclosed emitter protects the optic from debris, moisture, and environmental contamination while the hard-anodized Class III aluminum housing with reinforced sidewalls provides exceptional impact resistance. At just 1.13 ounces, the MPS-C adds minimal weight to a carry pistol while maintaining Steiner’s uncompromising durability standards.
Despite its compact size—measuring just 1.46 x 1.27 x 1.08 inches—the MPS-C gives a clear, distortion-free sight picture through a protected, recessed window shielded by a thick metal shroud. The optic features a true 1x magnification and a crisp 1.6 MOA red dot, enabling fast, both-eyes-open target acquisition for close-range defensive engagements and high-stress scenarios.
User-adjustable brightness includes 12 illumination levels, with 10 visible settings for day and low-light use and two night-vision compatible modes, ensuring adaptability across lighting conditions. Powered by a CR1632 battery, the MPS-C offers an impressive 46,125 hours of continuous runtime on the lowest setting, 13,000 hours at medium brightness, and is supported by an integrated motion-sensing “shake-awake” feature and user selectable 13-hour auto off that conserves power without sacrificing readiness.
The Steiner MPS-C joins the company’s growing lineup of premium pistol optics, giving concealed carry users access to proven durability, enclosed-emitter reliability, and compact concealment performance—without compromise.
Colona, IL (March 2026) – Rock River Arms, the industry's most respected name in Modern Sporting Rifles and pistols, wants to remind everyone that the newly implemented “zero tax” on NFA items doesn’t only apply to suppressors but also to Short-Barrel Rifles (SBRs). To celebrate, RRA introduces the new 10.5-inch A1 Carbine SBR.
This retro A1 Carbine SBR is an ideal pairing for anyone looking to run a suppressor on a high-mobility, exceptionally maneuverable defensive AR platform. This “old school is the new cool” configuration is the perfect SBR for those who value operational simplicity and no-fail performance as the base for their suppressed home defender. With its lightweight, chrome moly 10.5-inch A-1 barrel assembly and CAR gas system, the A1 Carbine SBR with an attached suppressor (suppressor not included) is compact and easy to handle in close quarter environments.
The A1 Carbine SBR comes chambered in 5.56 NATO/223 Rem. and is built on RRA’s forged LAR-15M lower receiver and forged A1 carry handle upper. The barrel is fitted with a conventional F-style front sight/gas block and A1 flash hider (1/2-28 thread) and hosts a classic A-1 triangular handguard.
Two variants of the A1 Carbine SBR are offered: one with a multi-position M4-style stock and the other with a fixed entry stock. Both include RRA’s A1 grip and single-stage trigger.
