Many of you will recognize this rifle from, once again, video games. The Zastava M91SR is an AK patterned rifle chambered in 7.62x 54R. This round has been used since the 1890s and is often recognized as the cartridge used in the Mosin Nagant. The M91 is a modern take on the M76 and the SVD (Soviet Dragunov). While it's not a perfect copy of the Dragunov, it is manufactured by the same company that produced the M76 in the 70s.
When we first received the rifle, it had a few items removed for the sake of import laws. One of the issues we addressed was the threads on the barrel. From import, they installed and welded a thread protector so that no muzzle device could be added. In typical T.REX fashion, we removed the thread protector and installed a flash hider. We may not have a great need for the flash hider, but it sure rounds out the look of the gun. The night sights and a bayonet lug were other items they had removed for import laws. At this time, we don't intend to track down more parts for this build and will have to live without a bayonet on the end of our 48" rifle.
While this build has a 24.5" barrel, we have not found it to be the most accurate. This could be because the AK platform was never designed to be a precision rifle, or it could be the steel case Tula ammo we are shooting. In any case, the three-inch groups at 100 meters are still "minute of man."
The POSP fixed four power optic was shipped with the gun. The POSP does offer illumination, (albeit very iffy) and a chevron-style reticle. The glass is better than cheap, modern optics but not nearly as clear as the ACOG or Razor that we are more accustomed to.
"The top center "chevron" (^) is used as the main aiming mark. The horizontal hash marks are for windage and lead corrections and can be used as mil marks for ranging as well. In the bottom-left corner is a stadiametric rangefinder that can be used to determine the distance from a 1.75 meters (5 ft 8.9 in) tall person/object from 200 m (2) to 800 m (8)." -Quoted from (Zastava M76 | Military Wiki | Fandom)
While this gun is still being used in combat today, we would instead acquire something like an AR10 or SCAR 17 as 7.62x51/.308 is a lot easier to source than the Russian 7.62x54R. The rifle's ergonomics also don't play as nicely as an AR-style rifle. Even the crown on the stock is aggressive and non-adjustable compared to the Magpul PRS or the B5 precision stocks that offer more adjustability and comfort.
When it comes to sling placement, we prefer one side near the grip and the other just forward of the optic. This allows the sling to hug the shooter instead of being stretched across our back. As you can see, though, the M91 comes with designated sling placement, so we went that route. We reduced failure by not using additional hardware and looping our sling around the stock and back to the tri-glide.
On the front, we chose to utilize a clash hook. This gives us the ability to detach the sling if we have unforeseeable issues. While these can be pretty noisy when moving around, they are still a viable option. If you want the adaptability of clash hooks while keeping noise to a minimum, Blue Force Gear ULoops may better suit you.
As you know by now, every gun needs a light. You can only shoot what you can see, and you don't want to shoot anything unless you visually confirm what is in front of you. For the sake of durability, we installed a SureFire M600DF to the Fab Defense BSR1.
We then chose to run a SureFire ST07 with a SureFire UE Tailcap up to the DF for easier light activation since the light is mounted in an awkward spot to use a standard tailcap. The ST07 is routed around to the left side of the gun and mounted with the included adhesive velcro.
To round out this build, we added a Harris Bipod on the bottom rail to help support what is a relatively large and cumbersome rifle. Harris bipods, while very simplistic, are well known to be reliable performers and are relatively inexpensive compared to other options on the market. The model used in this build is the standard sling stud mount, but they have quite a few options available.
All in all, the rifle is simple and nearly barbaric in its design. The box magazine's rough edges and sharp corners clearly display the need Russians have for reliability over comfort. True to AK form, the gas-operated, short-stroke piston system just works. With all the complaints we may have for the rifle, we can't deny that it goes bang when we pull the trigger.
On that note, though, it has slam fired twice, but you know the old saying… "One is none, two is one."
