This is a detailed guide on disassembling the A&K Dragunov from flash hider to hop-up. There are disassemblies on the YouTube but none I've seen get this detailed into the trigger box. I don't take everything apart, just get you in so you can get whatever you need done.
-Remove as few screws as possible. If it can simply loosen and allow disassembly, leave it there.
-Keep track of your parts. I tape and label mine to paper.
-1mm Allen Key
-2mm Allen Key (5/64 inch)
-3 1/2mm Allen Key (9/64 inch)
1) Remove Magazine.
- Remove all optics from the SVD side rail. (Optional)
Hand guard and Front Assembly.
1)There will be three grub screws under the barrel of the SVD.
One is under the front sight, another is under the gas tube, and the third is under the base of the hand guard. Remove them all. Remember to leave them in loose if they will stay.
2) Remove the handguard lever by pushing it in toward the barrel and then out toward the front of the gun.
It should slide out of the gun after disengaging.
3)Slide all front assembly parts off of the barrel and put them aside in a place you'll remember. Note: The newer SVD models do NOT have handguards that split open.
You should have this:
4)Remove the set screws holding the hop-up/barrel to the front assembly. They are located on each side of the protruding black part. Remember the tip of leaving screws partly screwed in if that helps you with organization.
5) Slide the hop-up and barrel out of the gun. Your front assembly has been taken apart.
