In all the years I hung out at Falfiles and building FALs, I was never aware of the gap you're talking about being an issue. But I don't claim to be an expert. Contact Gunplumber (Mark Graham of Arizona Response Systems and member of FalFiles) for clarification. He is acerbic and unapologetic but knowledgeable and even helpful. He won't guide you wrong.
 
Thank you. Sent an email 2 days ago. Nothing yet and falfiles has like 0 admins on ever so i cant post. Im just gonna give him both rifles back and give up on owning a fal. Thanks for the help guys. Im done
 
Unless you buy something from Mark don't expect any personal answers. He is all ways very busy building the best FALs ever . He told me to be really good they ALL need individual attention because of the design. I did build successfully two rifles , a Para Imbel and a HB Israelian , after he did my first two. I kept his builds and sold my builds which worked well but aren't as primo as his which he refinished ect. . Downlad the file I gave you and proceed from there with a set of head space guages.

The issue you may or may not be aware of is on some metric receivers and barrels know to be " in spec" (Imbel) the barrel face contacts the breech face BEFORE the barrel times correctly, many people miss this and keep cranking on the barrel. The fix for that problem is to turn the barrel face until the barrel can be timed and torqued correctly without contacting or just kissing the breach face.

The OP thinks he has the opposite "problem"... But is actually more conducive to accuracy for the barrel face to not bottom out in the receiver.

It must be remembered that we are not dealing with new parts on a FN receiver... but a reverse engineered aftermarket receiver from a company known for substandard manufacturing and assembly, using parts from rifles that may have seen every war, insurrection, and police action from the 50s to the present day.

I would suggest NOT trying to personally contact Mr. T. Mark Graham. He provides a great product, both in assembling and disseminating build info on FALs with his workbook and CD, but he does not have the time or personality to baby sit.
The very fact that someone posted in this thread a very old out of date manual might (rightly) set him off for the "theft" of intellectual material.
 
Would be great if a date stamp was on each post, so I'd know how old this most recent post is. Was this issue ever resolved? I can help the O.P.
 
You mean like at the bottom of your post, where it would say something like "AirBorneEngineer, 30 minutes ago"?

Welcome to the forum. You can send the op a pm to let him know you want to help. In case he unwatched the thread.
 
Meant a date stamp, as I'm still getting used to the layout of this board.
After a post is one full week old, a date will appear and it will no longer be the previous Monday. So tomorrow the OP's post will say February 17th instead of Monday at xx:xx

Hope that helps.

Ok i got the rifle functioning. I used an extra washer on threads of barrel got it to torque while being 12 o clock so barrel timed. I made a go/no go guage out of a hand loaded round with no primer and discs epoxied to the bottom then micing and sanding till in spec. Then i turned down some dif size allen wrenches on lathe to make pin guages. I welded more material to locking shoulder and milled it to .270 headspaced perfectly. Had trouble feeding a few rounds i changed the unibrow angle a bit fed perfectly. Rifle fires and cycles 7.62 on gas setting 5. Thanks for the help guys

Are you going to order the correct locking shoulder now that you know what size you need? The shoulder you made will wear fast if not properly heat treated. Good job getting it to run.

Yes already ordered though weld is harder metal i used a 7018 rod.
