I'm going to most likely put a rail from ACE on the lower handguard of my rifle for my M97 and a forward grip.

I was wondering what some of you though about the SOG Armory and the ACE H&K style grips.  I see the ACE grip is machined from Derlin, and the SOG grip is made from some type of polymer.

ACE H&K Style Grip

If anyone has any other ideas in about the same price range, let me know.  These are both rigt around $30.

I have a KAC. I'm waiting for the new one from Tango Down.

Yes!  Cant wait for the Tango Down!

I've heard Delrin isn't as durable under hard use.  Depends on your plans.  I love the shape of the little HK style, but would prefer a more robust design.

I have the SOG Armory grip, I like it. It has a nice, rubbery grip, feels good in the hand. It feels like it would be pretty non-slip due to the material on the grip.
