Edgun 30 Cal Pellet Clipping and THE FIX – pic heavy
OK. guys.. Go easy on me !!!! I am by far NOT a Professional Machinist…. Just a half ass Hack 😯
Part 1 : Upon discovering the pellet clipping problem after delivery of my R3 30 cal… At 7pm Friday Night…. I was on a mission !!!
So I first made a “Moderator Nut” removal tool….
Part 2: Early Saturday morning I had the Inspiration to modify the above to add an “Alignment Rod”.
The idea was to have a “Stepped” rod that fit Snugly into the Barrel while at the same time holding the moderator in alignment… All while being able to tighten the “Moderator Nut”……. Piece of Cake… 🙄 🙄 🙄 🙄 🙄
(and not damage to barrel and Crown)
The idea was to hold the Moderator in line with the Barrel while “SLOWLY” snugging down the “Moderator Nut”. This was a slow process to turn the nut 1/8 at a time … Remove the tool, Then check for alignment and then Repeat until the nut was Tight.
After Reassembly of the the gun. I did a final check with the alignment tool to ensure that nothing had shifted. I am happy to say I accomplished this on the first try. The rod slid in the moderator and snugly eased in the the Barrel. ( I did my best to hold less then 0.001 tolerance on the Barrel alignment Rod fit and then stepped it up to fit the Moderator hole.
This was what the moderator looked like after 20 shots… I think it worked 😀 😀 😀 😀 😀
And for “Big Eddie’s” Reward,… I topped him off with a nice piece of Glass…….
NOW i bet you guys want Chrono Strings … DB Reading…. Accuracy testing…… I AM TIRED AND HUNGRY … MORE TO FOLLOW 
Mark…
Happy Edgun Owner…..
…. And Yes O.G… We will talk later …. 😆 😆 😆

I just nailed a Christmas sparrow with my 30 cal out of a tree but I’m too full of turkey and fixin’s to go out and look at what’s left.
I plan on putting the Casio on to record some of these.
Send it to me! I’ll keep it.
Send it Ernest….. He will tune it too…
Personally, I have taken the removal process to the point of damaging the gun. That’s when I decided that opening up the baffle holes was the least invasive way to go.
Some people can unscrew theirs with hand pressure only. I’ve used vice grips, pipe wrenches, bench vice, etc… and it was all for nothing. For reasons unknown, some of those damn things just will not budge.
Don’t damage your gun. The amount to be removed from those holes is so small you could use a rat tail file and get the job done. Personally, I used a Dremel with a chain saw sharpening stone, which is long and thin and easy to go in circles in those holes. The stone is only about 1/4″ in diameter, 1/2″ long. Or, a round, fine toothed rat tail file will do.
Good luck. This is an easy fix, just don’t take too much off. The tolerances are quite small.
this moderator nut is getting the best of me. ha!
not sure if i got a cold barrel w/ a warm nut during assembly, but this thing is on tight. would penetrating oil help or hurt things?
easiest path at this point may be identifying the baffles being struck and try and sand/dremel them out a touch.
When you put the barrel back on, put it back on with some serious pressure. Ed likes things pretty tight.
Just a thought.
I figured you might need it to get that barrel tightened back up correctly.
thanks

no, i don’t think i have seen it. I’ll go look it up.
thanks

Have you seen the youtube videos on removing the R3 Edguns barrel? Ernest does very good disassembly and assembly videos too, thankfully, but I am not sure he has one of the R3 but I could be wrong. He explains stuff really well and his close-in video is very good.
i am ususally pretty good about tearing things apart, but little success of getting stuff back together. hoping for a xmas miracle tonight as i tackle this. 😉
good point on the o-rings.

You mean we aren’t the smart guys? Our IQ’s alone must total 100.
Take the orings off before heating that nut too much. 😀
thanks. i thought about the dremel idea, but really want to get this aligned correctly.
looks like i’ll try tonight to get the moderator nut loose w/ my heat gun and wrench. I was surprised the barrel came out so easily when trying to get the moderator nut loose.
i assume since there are no mentions of torque ratings, that a firm hand tight is tight enough for reassembly.

Ed is known for putting his nuts and stuff on really tight. When it comes loose, it does so quickly but takes a lot of force for some guns.
If you have someone to hold the barrel with some non-slip gloves, heat that nut with a hair dryer till it is quite hot, then hit the end of your wrench with a hammer, hard, and see if the nut comes unstuck. My experience has been it takes a jarring blow to break loose what Ed has joined together. Slow and easy probably won’t get the job done…this is brute force upon initial contact with the wrench.
Perhaps someone more sophisticated can add advice here. I’m not all that bright, but I’m smart enough to know heat expands metal and cold causes it to contract. I wouldn’t use anything hotter than a hair dryer on “high”.
Or….get an alignment rod (dowel, aluminum, whatever…) and see which moderator holes are off center. If you can identify what baffle/baffles are clipping, just Dremel them a tiny bit larger. Remember, we are only talking a possible thousandth of an inch off. Sometimes the easiest method is to simply enlarge the holes a very tiny bit, and the clipping will stop! That tiny bit won’t affect the efficiency of the moderator, but it will stop clipping. Many a baffle has been brought into alignment with a very tiny bit of enlargement. I’d leave the very end baffle untouched for cosmetic reasons, unless the clipping continued. The lead dust will tell the tale if it is one of the culprits.
Ok…now someone smart help this guy!!! (No offense Secoda, you beat my post by a few seconds!)
You are going to have to put the barrel back in the gun and tighten it correctly anyways since it was not tightened properly in the first place so I might start there. I did not have much trouble removing the moderator hex nut. I just read this thread, though, and I don’t agree with everything stated here. Rotating the moderator in and of itself doesn’t necessarily make it align or not align since the hex nut and barrel hole is already lined up with the holes in the moderator (but you might get lucky). It may just rotate the contact point around if there is clipping. That is why the ones with the hole that appears way off from the front may shoot just fine. When I put an alignment rod in the barrel it appears that the moderator alignment is slightly off and points slightly down as the gun sits level and upright with the moderator offset aligned as Ed intended. My gun was close enough that all signs of clipping disappeared as the barrel broke-in but the alignment rod still shows that the pellet travels very near the top of the front hole of the moderator. I believe that loosening the hex nut and then apply a slight upward pressure on the front of the moderator from the bottom may help a bit as I think F&D said he did if it is off only very slightly. A very thin shim at the bottom of the back plate of the moderator also might work between it and the barrel if the upward pressure doesn’t work and it is way off. Just my opinion. Once you get the hex nut loose its easy to test and try things. 🙂 I don’t mention drilling because I am not crazy about it. The hole is pretty large in the baffles already. I am curious if other 30 cal owners are seeing clipping since I assume the same cast was used to make all of the baffle units.
I am reluctant to put the barrel in a vise and try and break the nut loose, so I am looking for suggestions.
happy holidays.

thanks for all the advice.
being full of xmas fixing is a good thing.
