ATN COCKING LEVER, INSTALLATION, AND ADJUSTMENTS NEEDED!
:hoot:
YES! It’s all metal. It’s quality construction!
The kit contains loose parts that YOU will need to install. Most of the kit is pre-assembled, so don’t panic when you look at the picture and don’t see corresponding parts in the bags.
First….the parts list… but some are already assembled in the kit, note my arrows as I tried to determine if everything arrived:
Now, this is how all the parts ended up as “assembled” or “loose”….note there are only six parts you actually need to ‘install’.
Here are the parts you need to attach…two short screws in the front, two long screws in the rear that attach the cocking block to the side of the gun, and finally one screw to attach to the gun’s internal cocking bolt. That’s five (5) moving parts to attach…the cover plate does have a right and wrong side! Look for the side with the angled hole entries, that side faces out.
Now…a word of warning, take note, at the far right of the below image, the block the lever is hinged to (201) and it’s two screws (210)…are ADJUSTABLE parts, and must be leveled before tightened in place. Fail to do this correctly and the gun won’t cock smoothly, if at all. Bold print at bottom of post explains all….
I’m going with a left handed installation.
CRITICAL INSTALLATION CORRECTION…MUST READ!!!
THE LEVER (PART 204) ATTACHED TO PART 205 MUST BE LINED UP CORRECTLY BEFORE TIGHTENING THE TWO LONG SCREWS THAT HOLD PART 201 IN PLACE AGAINST THE SIDE PLATE! PART 201 IS ADJUSTABLE IN POSITION TO PERMIT THE COCKING LEVER TO OPERATE SMOOTHLY, IT IS THEN LOCKED IN PLACE BY THE TWO LONG SCREWS (PARTS 210).
I suggest the following sequence…
1) SNUG-TIGHTEN THE FRONT TWO SCREWS, THEN START THE TWO LONG SCREWS THAT HOLD PART 201 TO THE SIDE PLATE, LEAVE THEM LOOSE.
2) NOW ATTACH PART 205 WITH THE THICK SCREW 208 TO THE SLIDING CYLINDER INSIDE THE GUN…YOU MAY TIGHTEN IT FIRMLY AT THIS TIME.
3) THIS IS IMPORTANT…YOU MUST “ADJUST” THE ANGLE OF PART 201, THE HINGE BLOCK, SO THE COCKING LEVER IS LEVEL AND SLIDES BACK AND FORTH SMOOTHLY! PART 201 DOES NOT SCREW AUTOMATICALLY INTO IT’S CORRECT POSITION.
4) YOU MUST GENTLY ADJUST PART 201 UP/DOWN UNTIL THE ATTACHED COCKING LEVER TRAVELS LEVEL AND EVEN INSIDE THE SIDE PLATE. FAILURE TO DO THIS CAUSES PART 205 TO “GRIND” AGAINST THE COVER PLATE, AND THE COCKING LEVER BECOMES EXTREMELY DIFFICULT OR IMPOSSIBLE TO MOVE.
5) ONCE THE COCKING LEVER MOVES BACK AND FORTH, BUTTERY SMOOTH, AND HOLDING PART 201 IN PLACE, CAREFULLY FINAL TIGHTEN THE TWO LONG SCREWS (PARTS 210) THAT HOLD PART 201, TO THE SIDE PLATE. WHILE TIGHTENING THESE TWO LONG SCREWS, MOVE THE COCKING LEVER BACK AND FORTH A FEW TIMES TO ENSURE THE COCKING LEVER IS STILL LINED UP STRAIGHT, BEFORE FINAL SNUGGING THE TWO SCREWS DOWN.
CAREFUL INSTALLATION OF PARTS 201 AND 210 ARE THE KEY TO PROPER ALIGNMENT OF THE COCKING LEVER, AND IT’S SMOOTH OPERATION.
(Phew!!! I’m tired. It took three hours to pinpoint the real cause of the problem.)

got mine today, super excited. I had to grind my rear screws they were in fact too long. So not sure why there was a comment stating that the screw was too long then it’s not. Odd. great mod. simply awsome. 5 min install.
Received mine today. Well most of it anyways. My side plate was missing.
Still was able to attach it using the short screws and test it out. Wow! SO much smoother cocking action. The effort only requires one finger instead of levering so hard I often used my thumb behind the picatinny rail to get enough leverage. Like others have commented, the end of the travel backwards has a very definite feel.
I added a thin rubber pad to tame how the lever and short arm strike each other. The pad had a long base that snugged into one of the holes in the handle. No more click when the lever is cycled forward.
The best discovery is that if I hold the Vulcan anywhere more than 70 degrees up, the breach will stay open. Gravity is enough to hold the new lever open if the gun is pointed up. There IS a way to hold the gun and load a magazine other than Hoot’s “lever dangle.”
A small neodymium magnet mounted to almost touch the the concave slider piece (205) just as it reaches full rearward motion would be an easy way to make the lever hold open automatically even when horizontal. I think I will mount a magnet on the side plate once I get a slide plate.
Can’t wait for mine to arrive.
:hoot:
I routinely put in another magazine in mine while holding the lever back. It’s no big deal and no more problem than before with the OEM bolt. All I do is let the muzzle drop and hold the gun by the cocking lever as I slide another magazine into place. It’s NOT going to break because of it’s all metal construction.
I do like the solid feel of “cocked” and “locked” when pulling the lever back and returning it to firing position. Nice positive firm feel. No slop!
Great improvement over the original system. Vulcan is not wise to let this mod go unnoticed on their next upgrade!!!

UPDATED INSTALL INSTRUCTIONS 1/7/2017:
With the lever installed, can you still load a magazine while holding the Vulcan (not on a bipod nor bench)?
Can’t wait for mine to arrive.
I just got mine in the mail today. The install wasn’t hard at all, at least not after reading the instructions on here. Mine didn’t come with instructions. Wow does it make a difference on the gun. Super fast to cycle now. I hope it is standard on all new Vulcans.
Awesome…very nice upgrade for the Vulcan!
Thanks!

Looks and works great! :8:
I think the mechanism is very similar to the HW100….
Well, lets see this baby in action! Vids/pics?

Seem to have lost Evgeny’s email could someone please message it to me?
:hoot:
Dolt!
The kit is fine! I was the problem!!!
:hoot:
PS: I can’t be certain, but I believe my wife might be pissing in my cereal! My Captain Crunch tasted salty this morning???
Yea, no doubt! I have a .25 cricket he did his magic on and that sucker is lights out if I do my part. It for sure is more accurate than I am.
I’ll post up after I get the lever on and worked in. I also got a synthetic stock I put on it just before sending it off to Ernest. It’s like I’m getting a whole brand new gun!
Salt your going to love your tune. Think I’ll just wait awhile before getting this side lever. All the problems will be worked out by then.
Thanks, Hoot. We let you walk first so we can avoid the booby traps.

I thought the lever was aluminum????
I got a “Sorry we Missed You” notice in my mail box. Wife was home all day. I guess the mail lady decided to just not get our of her truck :angrymob:
