AA 12 1/2" forward grip and FDE Grendel mags

[jurassic]

I possibly want to change out my forward grip or tube. Will taking it off affect the accuracy or integrity of the upper as I am sure Loctite was used at AA when it was assembled. Also should I get a shorter or longer one. This is only used with a bipod so where the bipod attaches is probably important?? Also looks?? Too long might look....

I believe heat might be needed to remove the grip?? I am very hesitant!!

Also has any one seen Grendel mags in FDE?

Thanks.

It's been mentioned several times that the AA hand guard nuts are basically glued on. Several have had to resort to heat and lots of colorful language to get them removed. I would call AA before doing anything if you intend to remove it.
