hey guys, currently i have an nj compliant sig556, probably my favorite rifle thus far. problem is, i am looking to switch up to stock to the magpul ubr. issue is that with the folding stock is pinned, and im not sure if that will hinder me from accessing the mechanism in which to take the current one off, and put the attachment that i need on to accept the ubr. best friend is a leo in ny, and though he has a working folding stock, he said i would not have an issue. any of you guys have experience with this? comments are appreciated. thanks!

You're replacing the stock... not just trying to change the LOP... so it's not the biggest of deals if you damage the current stock, right?

 

You'll have to remove the current buffer tube that's on there too... the UBR comes with it's own buffer tube. (I'm pretty sure it's proprietary.)

 

Be sure you pin your UBR.
