ALACRITAS INNOVATIONS PRODUCTS

ALACRITAS INNOVATIONS designs its equipment in the United Kingdom with a clear focus: precision-shooting accessories that deliver measurable gains in stability, repeatability and shooter comfort behind the rifle. The brand grows out of shooters who actually spend time on the ground – training, competing and spotting – and who turned their own requirements into products such as the Fortis rear rests, recoil-management devices and purpose-built tripods. The ethos is explicit: function first, looks second, with controlled manufacturing and a product line centred on prone shooting and serious mid- to long-range work.

ALACRITAS stands out through a combination of three factors:
– a problem-driven approach: every product starts from a concrete issue (rear stability, recoil control, prone ergonomics) and is dimensioned to solve it, rather than being a rebranded generic accessory;
sound mechanical design: linear kinematics on the Fortis rear rests, fine but repeatable micro-adjustments, robust interfaces to the stock or tripod, all built to handle real-world round counts and field abuse;
– a focus on modern precision disciplines: PRS/NRL-type shooting, long-range rifles, prone work with high-mounted optics and constrained body positions.
Choosing ALACRITAS means opting for accessories that help the rifle track straight, keep the position consistent shot after shot and make impacts easier to read, instead of just “something to rest the buttstock on.”

THE FORTIS - MICRO ADJUSTABLE

The Fortis Micro Adjustable Rear Rest replaces a whole stack of rear bags with one rigid, height-adjustable system: an acetal copolymer / aluminium chassis, non-slip gripped feet, modular cradle “ears” for 18–25 mm stock widths and a height range of 90–160 mm (floor to base of bag). Elevation is set in two stages: coarse adjustment via the articulated legs, then 10 mm of ultra-fine travel through the micro-adjust “mariner’s wheel”, allowing the shooter to dial the exact point of aim without breaking position behind the scope. Despite the mechanism, it remains portable at around 2.1 kg, roughly 160 % lighter than a conventional rear sandbag, and folds into its carry case for transport.

The Fortis Micro really shines wherever repeatable rifle positioning is critical: prone long-range work, F-Class and Benchrest, zeroing and load development, or any training session built around a clean, supported rear. It is especially valuable for shooters who switch between rifles or need different sight heights; instead of swapping bags, they simply adjust the mechanism. The payoff is straighter recoil tracking, fewer unwanted movements at the buttstock and more reliable, readable impacts from shot to shot.
