another bullet guide question

[anothermotorhead 0]

I just got in the bullet guide I ordered from kvar abd i cant see how it is gonna work. the rivet hole is off to one side and all the ones ive seen for x39 are in the center. Did i get wrong guide?

[bshoop13 0]

With these bullet guides, I beleive they sit higher on the left side. Your hole will still be in the center

another question. It has a square bottom on it, and i have a round trunion. can i grind it down to fit the round trunion?

[gtnichols 51]

Oh,.. some pictures hear are really going to help, especially if you do a before with the square part and an after with yuor rounding, and then how you did it,..

There are different types, I would find the correct one.

Being that you posted this in the 7.62x39 section, and I could only find (1) x39 guide on K-Var's site, I assume you got this one: http://www.k-var.com/shop/product.php?prod...=281&page=1 ?

 

It looks to made for a flat trunnion.

 

 

I'm not sure if you could grind it down. Does it look like there's enough meat on it, to grind some away? I can't tell from that angle.

From looking at the guides on dinzags site ithink i can. Had i found this site or dinzags earlier than ordering from kvar, i would of ordered dinzags or manufactured my own. By the way do you think it is possible to weld a small bead on the trunion to make a guide.

From what I heard the flat trunnion sits lower than the round because it was actually round but milled flat so by rounding the flat part off It would still have enough meat on it.

[SOPMOD 254]

I just did 3 of these(two flat and one round)

 

For the round you will have to grind the square part off the bottom and cutoff the left "ear" and for the square trunnion you just cut off the "ear"

 

I used the Dinzag feedramp on the first one and it was a smoother installation and so far not a single malfunction on 350-500rds and I used modified K-Var feedramps on my buddy's two Saigas reworked as I describe above

I used that same BG in one of my Saiga builds recently - the saiga was a 'round bottom' like yours. I ended up lopping off the right side of it (the side that had the hole in it). I then redrilled the hole (and chamfered it with a 60-degree countersink), and filed off the remaining 'flat' part underneath, as well as the 'ramp' that is used to turn the bolt on the left side.

 

Here's what it looked like after I redrilled a smaller hole and riveted it in:

 

 

Notice on the very far right side of the BG that you can still see a tiny remnant of the original hole. This worked well and is feeding fine.

beautiful work as usual 30cal. that looks like atleast an 1/8th inch overhang though. or do you have to grind it off. asa for my last question,CAN YOU WELD ON THE TRUNION

Yes the overhang is intentional and correct. The overhang is what gets the bullet nose lifted out of the magazine feed lips, popping it up into the chamber. I have another I built with a dinzag BG with no overhang, but the dinzag BG is thicker than this Bulgy BG. Since it's thicker, it lifts the bullet nose up high enough to still make it into the chamber... Personally I prefer this modified Bulgy BG over the Dinzag.

 

As for welding on the trunnion. Yup it has been done, but I don't recommend it :

I think Tennessee Guns (?) does that in the conversions they sell (which Atlantic Firearms sells also).

 

Not my cup of tea, but one guy came here and posted that it works. I'd still opt for a real bullet guide, personally.

HELP!!!! What is the best way to install the rivet. I tried an air hammer with no luck, and should i have the head of the rivet on the bottom?
