The ace products are quality.

The weld pack is 1/8 inch metal and makes an extraordinarily hefty receiver.

I have done them by wrapping them around a piece of 1.25 inch key stock. The metal stays perpendicular and the stock acts as a heat sink.

The upper rails will have to be cut out and installed separately.

thanks rwinn ! upper rails. do I get A piece of 4130 of thinner stock and weld it inside on the front of the receiver and fit my front trunnion to it? also, on the ace tutorial it says to trim about a 11/4' off the front of the blank. I realize the tutorial is not for a weld pack but does that still apply. can I just take measurments off my mak 90 and apply them to this buld with the exception of fitting the f&r trunnions to the amd65? man! does no one offer a set of directions for the weld pack? a guy could make a fortune!

Not at all, the weld pack is the correct overall length. Do this - clamp your weld pack together securely with one of the trunions in between for the exact spacing. Spot weld, remove the trunion and then weld the rest up and clean it up. That should get you off to a good start.

You can even make your trunion holes prior to welding the plates. Get the precise measurements of your trunion holes down on one of the plates, clamp the left and right side together flush and drill through them both at the same time; voila - holes that match on both sides!

boy, I'm about to ask an amazingly stupid question! if I'm welding this up, why can't I grind the cut rivets flush and weld the trunnion into the receiver? I'm not planing on taking this apart.

I've done a batch like that.
