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.

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