This guy is a pirate! A good gunsmith should be able to put it in adjust it for around $65.00. Who is the pirate and his shop name! We need put the word out on people like him. Look online for a Remington Certified Service Center. If they are close you could call make an appointment drop the rifle off go to lunch and come back and pick it up. Ours happens to be in Louisville, KY. There are many here I am sure on the Forum that are armorers that could install it for you but the only downfall is the cost of shipping, insurance and handling! It is not a problem to install just takes a little time and knowledge!
The Constitution is not an instrument for the Government to restrain the people. It is an instrument for the people to restrain the Government!
