Bull into receiver.. tight as hell.. best way ?

[DocBurN]

Without risking any damage, what would be the best way to fit a 12.5 bull barrel into a tight receiver ?

1) sand the black paint slowly inside the receiver and try to fit the bull often until it fit tight?

2) ... i got no clue.. violently hammer with a sledgehammer while laughing evilishly until the damn thing fits ?

3) Did i heard right when i read some of us actually freeze the barrel over night to make it fit ?

4) K-Y ? good ol lube!

What would be the best way to do it ?

Once again, thank you for your help as usual..

looks like it

received my toys in the mail.. was hoping for a quick tip from CGNers

Mine took a few twists but went right in.

I was ready to have to freeze the barrel and heat the receiver.

Warm the receiver with a blow dryer for a bit, and put the barrel in the freezer for an hr.

but if its too tight, or do the freezer / dryer thing, arn't you affraid the extractor wont fit in the middle of the bull notch ?

Why would you be afraid?

The Vblock will straighten everything out.
