The new Taurus T4SA is designed and built entirely within the USA and features a number of parts that aim to heighten performance and durability of the design. First, the rifle uses an M16-style bolt-carrier group for added strength, and the company claims that the additional mass works to reduce felt recoil during firing.
One of the main selling points of the Taurus T4SA is the use of Melonite treatment on a number of critical parts, designed to harden metal surfaces and add to the life of the rifle. The bolt and BCG are both Melonite-treated, as are the barrel and the gas block. The rifle is chambered in 5.56 NATO and can safely fire .223 Rem. ammo as well. The barrel features a 1:7 twist rate and has been tested with more than 10,000 rounds of M193 and M855 ball ammunition to ensure service life.
The low-profile gas block is dual-pinned to prevent movement and allows for a lengthened fore-end that continues past the gas block for more real estate and better control over the firearm. The handguard itself is available in both KeyMod and M-Lok configurations and can be had in lengths of 16 inches, 14.5 inches and 11.5 inches. The handguards feature QD attachment points for easy sling mounting.
Other features of the rifle include a Magpul grip and oversized trigger guard to allow for the use of gloves when shooting. The rifle comes equipped with a mil-spec buffer tube, recoil spring, H2 buffer and a staked castle nut. The stock on the Taurus T4SA is a Magpul CTR, equipped with a position-lock device that prevents rattling.
According to Taurus, the T4SA rifle exceeds mil-spec standards for durability and reliability, passing the performance requirements by 4,000 rounds. The company also claims it suffered an average stoppage of 1 round in every 10,000. The suggested retail price on the new gun is $1,199.
