I grabbed one of these today at TA and was told I would have to grind down some of the threading to get it on. I bit of work and I got it. BUT my spring guide and bolt will not fit down the buffer tube. It just get jammed tight at the opening. Is this a faulty buffer tube? I dont want to go all the way up there again considering I was returning something that was broken on purchase the day before.
:/

Show off some pics, I am having a hard time visualizing. Is the buffer getting stuck where the tube screws onto the receiver?

I'll grab pics in the morning. Everything including the rubber spacer gets stuck within the first 2 cm of the buffer tube. It's like it has a choke point or is just .1 mm too tight.
As it stands I think I'll be going back. The packaging was open and it was also missing the screw that locks the outer tube to the inner one. I had one that fit luckily.
