The right and left side of the stripped NDM-86 receiver. Top photo has the scope rail visible. Notice how different it is from the Saiga and Romanian scope rails. The scope on this version is attached by sliding from the rear forward. This is why PSO scopes that came with the Saiga rifle will not fit the Dragunov. |
 |
The import mark on this .308 NDM-86 is for Briklee Trading Co. in South El Monte, California. They are now out of business. A former customer described it as a very impressive place filled with many curios & relics, more like a museum than a gunshop. Incidentally, BTC imported over 50,000 Chinese Type-56 AK's, mainly MAK-90's and over 100,000 Chinese SKS's. BTC is the sole creator of the "Paratrooper" SKS with the cut-down 16" barrel, the modification of which was performed here in the US. |

The bottom of the receiver looking through the mag well. The bolt hold catch is visible at the bottom. This spring-loaded part locks the bolt back after the last round has been fired. |

 |
The military SVD receiver also has internal lightening cuts as well as on the outside. Russian receivers produced from early 1990's only have the internal cuts. More info about these cuts can be found here. |
 |
These lightening cuts lighten the weight of the milled receiver making the rifle slightly more comfortable to carry for extended periods. In the field every little bit helps! Current production Russian Dragunov receivers are completely flat on the outside which provides extra regidity to allow the use of more powerful calibers. |

The
trigger assembly is removed from the receiver as a unit and is numbered
to the rifle.
Looking from the top you can see the 2 stage trigger assembly. It is rather different from the Kalashnikov design. There is a rumor that the auto-safety sear had to be removed on Dragunov Tiger before they could be imported to the US because it was considered a class 3 part. |

 |
The diagram shows the restricted sear (6). The sear was never incorporated into the Chinese version of the design so owners of NDM-86's will not find it in their rifles. Though the US government might classify the sear in the same category as machine gun parts, the Dragunov is not capable of firing full-auto. The sear is actually an added safety device designed to prevent the possibility of the rifle firing a bullet before the bolt is locked into battery. |
|
In comparing magazines from the Russian 7.62x54R version (on right) with the Chinese .308 version you can see there are several differences. At right are the front end tabs which hook into the recess cut in the front of the magazine well of the SVD's receiver. Note the Russian tab design is taller. |
 |
The rear end tabs also differ slightly in their construction. Russian five round SVD magazine on right. |
 |
Front tabs in profile. The Russian magazine has a curved body because that is the only way to feed a rimmed cartridge reliably. |
 |
From the bottom you can see the most dramatic design difference. The Russian magazine body has a hexagonal shape which is tapered at the front. The magazine well on the Russian SVD receiver is similarly shaped. The Chinese .308 NDM-86 magazine is a more traditional box-type design with straight sides and a receiver magazine well to match. These magazines are in no way interchangeable. |
 |
The followers are very different as well as the feed lips over the rear of the opening. The Russian magazine must be loaded by inserting the cartridge at the middle of the mag and pushing back. The Chinese .308 magazine is loaded in the traditional manner of pushing the cartridge straight down into the body of the magazine. |
|
|
This is the bolt carrier which is also numbered to the rifle. |
 |
This part is very carefully machined and has almost no side to side play when resting on the receiver rails. |
 |
The bolt carrier on this Chinese NDM-86 sniper rifle has a hammer block designed into it. Above shows the bolt locked into battery ready to fire. The hammer has un-obstructed contact with the rear of the bolt and the firing pin. |
 |
If the cartridge does not get fully chambered, the bolt carrier does not allow the hammer to contact the firing pin. This safety feature is designed to reduce the possibility of firing the cartridge out of battery, which could result in catastrophic damage to the rifle and possibly the shooter. |
 |
The bolt for a .308 version. The only difference on the 7.62 Russian version is the face is machined wider for the rimmed Russian cartridge. |
 |
The bolt functions in a similar way to the Kalashnikov design, but only has 2 locking lugs, whereas the Dragunov bolt has 3. |
 |
This bolt has been retrofitted with the spring-loaded firing pin. |
 |
The top firing pin is from a Russian Tiger. It is designed to used a spring which is held in place by the little tabs on the rear. It is slightly longer than the Chinese version. |
 |
The bottom pin is from a .308 NDM-86 and has been modified by CDNN. A small hole was drilled and one end of a spring was inserted. |
