I really like the Hogue overmold stock.
It just holds 'perfect'.
They are currently being integrated into
my favorites...as fast as my wallet allows.
Another thing you may wish to consider....
an adjustable gas block.
Really changes the versatility.
And if you save brass, you won't have to
chase it down in the next county !!!
I will look for a link to post......
Generation #3 Adjustable Gas Block
scroll down to the 'block'
and browse their site while you're there.
