I purchased a urx ii rifle length and I want to install it on a SR-15. Anyone done this before and can guide me in the right direction.
You need to buy a URX wrench to be able to remove the URX off of the upper.
Alternately you can send the upper in and have the midlength URX removed and the rifle length URX installed from someone like Lawmens, MSTN, or Operation Parts.
The gas block needs to be grinded down a bit for this to work. Would these places do this modification for me?
Contact Lawmens.
Robb @ VA Arms did one yesterday. Contact him.
Big +1 for him

Marvin Pitts as well, particularly if you need custom barrel work, e.g., dimpling.
