Will the Hogue monogrip and foreend tube listed on clipsnstuff.com's website fit onto my SP1 (I want to keep the original furniture in its excellent condition)so want add furniture to use in 3 gun.And secondly anyone got this on Their AR and if so what do you think of it.
last but not least where is a good place to get a stock ass as well as I would also like to preserve the original stock.

Cheers
Nigel

I would definitely recommend the grip.  The tube, however, doesn't allow for very good barrel cooling/ventilation, especially if you're going to shoot it alot.  I don't know your AR experience, but the tube isn't a "drop-in" replacement for your older triangles.  It will require the removal of your flash hider, front sight base, & original barrel nut to install.  Depending on how you want your rifle to look/feel, there are MANY different choices for handguards & buttstocks.  An upgrade to a set of CavArms furniture is definitely a viable option.
