Re: Quads done
The days of $400 quads are pretty much over. There are two quads up on Gun Broker right now for $600 starting bid and I think there is an action up there too. The A5 stocks are ala carte, so it just depends on what features you'd like...type of cheek piece, cups, studs, etc. The wait time is around 4 - 6 months, it just depends. Their pricing is up on their web site. I have no idea how much manners charges, but I think it is less and the wait time is less aswell.
You can piece them together pretty easily with a little money here and there. The stock will set you back the most after the initial cost of the rifle.
Dan Lilja makes and stocks barrels for around $360.
Larry Gish does trigger work on them for $40 and has extremely fast turn around time.
Rimfire Technologies makes the optics rails, metal trigger guard, and various bolt knobs.
KMW also makes knobs, along with a couple of other companies.
J&P makes replacement action screws and springs.
The nice thing about the quad setup is you can shoot it while you build it up. The standard stock has a removable channel piece so you can use either a tapered barrel or bull barrel (while waiting for your mcm/manners to arrive).
