Very easy to install just unscrew the screws then take the spring and old plugger out put the new one in and the spring. it didn't come with a metal one and make sure you don't put to much grease only do 3 or 4 lines top to bottom to make sure theres not to much.

I would recommend it works great it jammed at first but you just have to pull the bolt back then let go so it doesn't jam.

Great Toy, works flawlessly!

я не получил товар и не могу его отследить . Когда я получу винтовку и как я могу отследить свой заказ где он сейчас?

The gun isnt much powerful and accurate but works pretty fine. Largest flaw is the PSO. Its completely one piece and not adjustable at all. So only way to hit the target is open sight shooting. But still - SVD is really good toy.
