Is there a diagram showing how to make 607 handguards from A1 handguards? I have a couple spare A1 handguards and thought about making a set.

Well, you need that stamped metal end cap.  Then it's just a matter of cutting the handguard and trimming back the heat shield.  Or, if you don't mine not being totally authentic, you can just buy those short triangle handguards...

ETA: I got one of those end caps from Primary Industries.  Don't know if they still make them.

Here's a thread from a couple weeks back that should answer your questions

I have a set of short ones but I like the look of the originals. Primary industries I'm not familiar with them?

Thanks for that. So basically both front and rear caps have to be made?

No, just the rear cap.

No, it's either front or rear. There were AFAIK some handguards shortened on the front and some shortened on the rear.
Most guys shorten the rear and that makes for a smaller grip area.


BTW..... Nice avatar!

Thanks
So were the 607's standard carbine length or smaller, IMO they look smaller. Also what would it take to make the rear cap?

Standard carbine length.

If you have a mill, you could make one with some time and effort. I think somebody brazed one together from sheet metal before. If your good at shaping sheet metal, you could hammer one out maybe.

The originals were stamped with a bracket brazed inside. Heatnbeat offers a very nice reproduction from what I've seen. Primary Industries had/has one that will work but isn't accurate. I don't know if anyone else is currently making them.

Ah ok. I can't seem to find Primary Industries, The only one I find is Primary Arms.

Our own member, HeatnBeat (Jerrel) makes a perfect one for $50. Not cheap but there is none better.

HeatNbeat for the win. Good things are not cheap, and the other avail cap that is cheap is not good.

Hm ok. I plan on using the front half of the HG's and have a few front caps, what I'm gonna need is a rear cap.

HeatnBeat have any available?

Got with HeatnBeat and am in for one of his. I did a preliminary cut on one of the hg sets I have, gonna have to wait to final fit when I get the end cap. I don't much like fiberglass but these only have one ear missing.

I am currently working on cad drawings of the 607 stock and handguards. are you using a repro rear stamped "cap" like the original? if so, I can give you my cad calculated length. i'm in the 607 build process too, and want to produce a complete set of drawings to post.

He's going to use one of heatNbeats, not the cheaply made poor repop. The cheap knockoff has the large thru hole centered up, not offset to the top, which will call for a different cut on the handguards.
  Correctly made rear caps allow for very little deviation on the "cut/trim" job on the handguards.

Yep, wait till the cap comes in and trim to fit

I just received my HNB end cap last week. Outstanding piece! Worth every penny.

ETA: Does anyone have pictures of the insides of their finished 607 HG's?

I got my cap from HnB also just haven't had time to fine tune the test hg's yet. Gonna try to do some work on them this week.

Had a little time this morning so I did a little trimming and fitting. Still have to cut the good hg's and acquire more parts for the build.

Those are nice caps. They make the handguard sit "lower" than the rear cap I have.
