gonna go out on a limb here and say you wont find it anywhere else on the net, especially not cheaper. I am pretty sure he makes the barrels (or has them made specifically for him) AKA "Palmers" Brass, but you may want to do some searching on this site, there are lots of people that say the porting doesnt do much (accept quiet it down). Also, unless it is for looks, "from what i hear and others have told me" you arent going ot gain anything by going from 12" - 14". I ordered the 12" unported. I am going to run some tests between that and the Smart Parts Barrel that I already have.

Good luck with your LPK. I have no idea, or I would suggest it.

I have heard that the single venting makes it more silent, but also gives it more accuracy. Double venting decreases the acuracy but makes it even quieter.

Somone correct me if I'm wrong?
