You want a beavertail grip I guess.
I wonder how the grip parts are held together.
Read the reviews,
"There is one draw back, the grip needs to be dremeled a little bit to fit my AR15 better. It's where the grip's heel spur is."
Seems to be somewhat common issue with beavertail grips.
"The only half complaint I have, if any, is you cant change the grips on the fly. It takes a little time and a center punch to pop the inserts out to change them if you let someone else shoot your rifle."
