I thought I would post this as a new thread so it might be easier for folks tring to bend these to find down the road


The grooves for the scope mount are cut after the flat is bent and welded. The rust is a non issue as everybody else has mentioned. These flats are a breeze to bend, somewhere around 5 minutes if you have a 6" wide vice and some properly sized drill rod.

Here are a few pics, the first pics shows the end veiw of the "flat" , after comparing this to another stripped rec it appears the cocking tube portion is the only bend left to form, and if you look closely you will see three short portions of the tube have alredy been partialy formed.







Basicly athe bending of this flat is much like bending an ak flat, I started with the jaws of the vise about 1.5" apart (similar to the top of the female ak die) . I ran a peice of 3/4" drill rod down the center of the flat and centered it over the opening in the vise and proceded to tighten the two clamps on the ends which quickly begins forming the shell, I took a peice of aluminum scrap an a hammer and hit the center of the drill rod a few times to insure the middle was bending properly. and tightened the vice a little as I went and here are the results












somewhere in the process of tightening the vise the top of the cocking tube will start to pull away from the 3/4" rod slightly and its time to change the setup slightly, What I did was put a peice of 3/4" sqaure stock in the bottom of the vise and the 3/4" rod thru the receiver and used the clamps to pull the rod and rec down snugly against the 3/4" sqaure. I then took two peices of 3/16" drill rod on either side of the cocking tube in the bend where it transitions from small to large and tightened the whole mess up in the vise . Also tapped up and down the length of 3/4" rod with aluminum scrap and a ball peen hammer . These pics should make it clear.

Bending these flats 100% straight like Hk recievers is very hard to do. Obviously Vector arms can not even do it since every one of the 4 recievers I bought from them was warped way out of true HK spec.

How is it that these clone companies cannot get it right?

They should have everything to do the job right.. but some how cannot.

I have heard so many bad things about Bobcat and Vector.... So glad I never bought one.

I have an HK94 flat that I'm not yet ready to "experiment" with, as it was not cheap.

Do y'all anyone who can bend my 94 flat?

I have a few people who are ready to build the rifle for me but I need this flat bent. (Trying to contact Jayson at IGF but I'm sure he's swamped for a loooong time)


Thoughts?

PS - Great thread and pics!

I'm having Jayson at IGF do mine. I picked up a factory HK flat and contacted Jayson to see if he could do it. He said he could and that his build time was in the neighborhood of 3 months. I've seen some of his work and have no problem with him doing the build. As far as I'm concerned his work is the full equal if not superior to factory HK. His welds are like an artform. Good luck, I can't wait to have mine built as I just got the flat in today.

Lt.,


As of about 2 weeks ago my entire kit and flat are in Jayson's hands. This flat was too expensive for me screw up.....

The flat is not serialized and can be shipped to anyone,not just FFL's. It is not considered a receiver or firearms, in the condition that the flat comes in. Once the flat is folded and welded, it is then considered a receiver and consequently a firearm. Jayson at IGF is building mine and he is adding a serial number and manufacturer markings as required by ATF when he builds the rifle.

Lt,

Are you going to be able to choose your serial number?

If you have a flat bent by Jayson he will add his manufacturing info and serial #. I'm not quite sure what he adds. Maybe an IGF logo or something. Does anyone know exactly what he adds? Is the stamp attractive or does it take away from the overall look?

the only flats I have seen have been made on HK tooling in Turkey. They are very pricey and supposedly HK is very upset about it. If you are looking for a receiver that is not HK then just get an already finished receiver because it will save you alot of money and or work in the long run. I am having my build made up from an HK flat because I want the build to be high quality and an accurate replica. You can get flats on gunbroker.com and finished receivers as well.
