poor terminal ballistics of the projectile and the complexity of the new weapon. Type 79/85 – A Chinese variant of the SVD. Although the design is nearly identical to the original SVD, some parts are not interchangeable, as the dimensions are slightly different from Soviet production rifles. A small quantity were also chambered in .308 winchester for export. Exported rifles are often referred to as the NDM-86 or EM-351. Al-Kadesih – An Iraqi variant of the SVD, not to be confused with the Tabuk rifle. Although the design is very similar to the SVD, many parts are not interchangeable due to its unique dimensions and design characteristics. For example, the receiver is not milled and is slightly longer than that of the SVD, and the barrel is pinned to the receiver instead of being threaded. The rifle is also issued magazines with an ornamental palm tree relief. TKB-0172 – An early bullpup design of the SVD developed by the Tula Sporting and Hunting Weapons Design Bureau in the 80's. This rifle also had a significantly shortened barrel to reduce length. SSV-6 (6V1-6) – Chambered in the experimental 6mm cartridge developed in the 80's. The weapon was not adopted due to the poor effectiveness of the cartridge. OTs-03 SVU – A variant of the TKB-0172 which began serial production in 1991 for the MVD. The rifle was also equipped with an improved muzzle brake as well as a rear aperture sight, much like the original SVD prototype. Many were not new production rifles, but instead, retrofitted SVDs. A select-fire variant (OTs-03A(S) SVU-A) was also produced in small quantities to serve as an automatic rifle, but the automatic fire capability was later removed from the design. The original shortened barrel was also later replaced with a full-length barrel in the design. SVDK (6V9) – An experimental Russian variant chambered for the 9.3×64mm 7N33 cartridge, based on the civilian Tigr design. SWD-M – A modernized Polish variant of the SVD adopted in 1998 which uses a heavy barrel, bipod (mounted to the forearm) and LD-6 (6×42) telescopic sight. CS/LR19 or NSG-85 – A modernized Chinese variant of the Type 85 adopted by the PLA in 2014 SVDM – A modernized variant of the SVDS which entered service in 2018. Compared to its predecessor, the SVDM was notably designed with a thicker (and 550 mm long) barrel, new furniture, and a picatinny rail mount
