Sabatti STR in stock Bolt Action .308 Rifles
The new Sabatti Tactical bolt-action rifle, model “STR” (Sabatti Tactical Rifle), is the latest addition to the already comprehensive range of tactical rifles manufactured by Sabatti. However, while its predecessor, the Tactical Syn. model, was designed mainly for precision target shooting, the STR has been created for tactical “field” applications where superior accuracy is required.
The STR rifle comes with the Sabatti signature short action and a 7-round magazine (5 rounds for the Italian market). The barrel is 0.8’’diameter at the muzzle and comes with 5/8’’-24 threads to fit most accessories available on the market today.
The rifle comes standard with a thread cup and professional muzzle brake with radial holes designed for precision target shooting. For true tactical applications, a 3-chamber compensator is available on request.
The Tactical modular stock butt and grip are machined from two solid blocks of high resistance Ergal 55 light alloy. The fully adjustable butt stock can be folded to a smaller size for ease of transportation. Additionally, the Model STR can be ordered with or without a butt stock as it fits all “M4” type stocks sold on the market today thus giving every shooter maximum freedom of choice.
The Sabatti barrel is fitted with a custom AR-style Picatinny hand guard that matches the 20 MOA rail on the action. Three additional rails on the hand guard can accommodate any accessory a shooter may want. While the action rail is in steel, the mating full-length top Picatinny rail and the side rails are all machined from solid billets of Ergal 55 alloy. A synthetic rod connects the barrel cover to the stock body to facilitate free-standing shooting or for ease of transportation with folded stock.
Multi Radial Rifling
Sabatti S.p.A has designed and introduced a unique rifling profile with different features over that of traditional rifling that, despite its overall effectiveness, has limitations especially when it comes to lead free bullets. Sabatti's objective was to develop a rifling system with all the positives of the traditional one and none of the negatives.
Every area of the bore in concave. There is no convex point protruding towards the center of the bore. Consequently the bullets are only mildly misshaped and not cut like in traditional rifling which extends the life cycle of the barrel. Also there are no sharp corners to fill like in polygonal rifling. With multi-radial barrels two different raduses alternate in order to slightly misshape the bullet geometry without cutting it and submitting it to extreme stress.
All the tests that Sabatti have carried out on multi-radial barrels prove that - under similar circumstances - less copper deposits inside the barrels and, therefore, less cleaning is required. Also, when needed, cleaning is much easier to do than with traditional rifling.
Multi-radial barrels have also proven to perform better and with more accuracy than barrels with traditional rifling using traditional lead bullets in cal. 7,62mm (.308") and cal. 6,5 (.264").
The results of the tests show that:
◾Speed is higher than with traditional rifling, up to 10% under certain circumstances.
◾Group concentration is substantially improved.
◾Number of Fliers is drastically reduced
◾Shooters can improve performance by polishing the bore with abrasive paste pads with no fear of ruining the rifling edges.
These are all the reasons why multi-radial rifling is truly ideal for target and competition shooting. And this is why now all Sabatti target rifles come with multi radial rifling.
The multi-radial rifling lends itself so perfectly to the cold hammer forging that the overall performance and quality of all the barrels has stepped up. The specific rifling geometry makes it possible for the chamber neck and freebore to guide the bullers into the rifling more precisely and steadily - the bullet matches the barrel axis in the best possible way thus reducing the fliers.
