Hello i am building a fulton armory Ar 10. I am having problems with the buffer tube. The Rifle buffer tube i got from Fulton armory with turn once then it gets very tight. I took it to two different local gun shops both said the threading was wrong. It will take the buffer tube from the car. Just wondering if any one else has had this problem.

Yes the buffer tube was from fulton armory. I even ordered another one to make sure. Same problem. I talked to a guy that build them at a gun show and he told me its a common problem. She said he would fix it for free. I plan to make a trip to his shop this Friday so he can fix it and check the head space for me too.

I received the buffer tube kit for my Fulton armory Ar 10. i have the Fulton armory upper receiver with the side cocking handle, and It is super tight trying to put it on. Is this a common problem?
