EDGun R5M cocking/indexing?

Jump to latest Follow Reply
Have you replaced the breech seal? I also know both @davidsng and @zx10wall put something behind the breech seal like a thin plastic washer to fix this.

I did that for a little while, then just got a slightly thicker o-ring. Now it works fine. Sometimes the o-ring will flatten out. It look fine when you examine it, but it is flat and let air escape. I have a dozen on hand and replace them about once or twice a year.

If you are reading this thread?

I want you to know that Edgun was on my list to have. It was just a matter of I had not picked up the phone yet. With the response "learn how to cock a gun, I will never own any of your product! With that attitude customer service only gets worse.

There are so many really ($) nice guns out there, why would I buy yours?

I ended up going to a 75 durometer Viton o-ring for the breech seal but the same size as factory. The most import thing that solved the blowback issue for me was to stop putting any lube on the breech o-ring of the R5 & R5M. This included avoiding any lubed projectiles that would inadvertently lube the breech o-ring. Sounds kinda weird, I know, but this solved the problem.......

Haven't tried other pellets so can't comment on that. The blow back in the face I get happens when I don't really push the bolt forward and hear a latching click. It has to be deliberate motion and if I get in a hurry sometimes I don't get 100% forward and get an annyoying puff of air and a pretty loud bang in my ear...which is right by my ear with a cheek weld. Seems to simple to be a solution but pellet depth in the magzine is also a pretty simple solution. Hope this helps.

Whoa, let's not get ahead of ourselves here. EDgun makes good products and you'll be only missing out. Some people get too sensitive when their pride is insulted. I have always received excellent customer service from Brian at EDgun West and so have many others. Show me a perfect airgun. There's always something to nick pick at.

I worry about customer support from them also. And you don’t have any choices but edgun west. I really want one, and probably would have bought one if they had them in stock. But my hart ( the smarter side of me) says to buy tipan. But I like the looks of the r5m so much better and I just keep putting off buying either one. ( nether of them are available right now any ways though. ) And I thought a read that tipan May have a front cocking model coming, if that’s the case I will buy a tipan long, only due to the lack of “ service- support” that I keep hearing about on the edguns.

Maybe semantics but, the magazine has every thing to do with indexing. If the pellet is not seated the magazine can not rotate completely and thus the jamming problem. Try cycling and empty magazine and sans pellets it will probably work perfectly. That and a finicky RTI Prophet magazine's stuborness to insert into the breech connected a few brain cells for me to think maybe there is a similiar issue with the Leyla. On the Prophet It seemed the width of the magazine was a few thousandths wider than the slot in the breech. At first a little silicone, I mean little, on the side of the magazine inititally solved the problem. Now after many shots and a little 'breaking in' the silicone lube is not necessary.

An empty mag is not a good simulation as a loaded mag has more weight and momentum.

fact of the matter is, the EDgun magazine system is crude! I like the rest of the gun and I love the single shot Eddys. The mag system needs refinement and it’s just time to put some engineering into the design so that it can catch up to not only the rest of the gun but also the competition.

Maybe not to you but for me it clearly identified there was a difference. Then the job was to find out what created the difference. I think weight and momentum have more to do with a pellet in flight rather than a magazine snugged into a loading port. Did get a jam so bad I had to remove the breech and dig out a smashed pellet lodged between the probe and the internals of the breech. Couldn't even remove the magazine. Doing the intermittent loading I sometimes double loaded the magazine and it jammed. Took the breech and stock off and turned the gun upside down and two pellets came out of the inards.

Thumbs up on the Edgun magazine system. It is rough and crude but it works...most of the time. It isn't as smooth and refined as a FX but I would like to see a truck drive over an Impact and see what needs replacing. Theres a you tube video somewhere of Ed doing that with the Dedal Stalker mounted on the Edgun.

The jams have to be either an under or over rotation of the mag, not stopping on a indexing dimple. If you short stroke the lever under rotation, stroke too quickly to the rear possible over rotation from rotational inertia rotating the mag beyond the dimples? If so, it should happen more often with a full mag and heavier pellets. Worn mags with shallower dimples could also increase the chance of over rotation.

Guys... before anyone overthinks this, We don’t need to discuss mass, inertia, momentum induced by empty vs loaded mag quite yet. The issue described is one of mechanical interference when pellets are not seated. I can tell you that there are very small differences in the id of the magazine chambers from hole to hole and from mag to mag... especially if one uses multiple brands of mags. Couple that with the variation we see in skirt diameter and the issue can be real.

I simply squeeze the skirt of the pellet and the forward section of the mag till I “feel” it seat.

Derrick, totally agree. Yes ts kinda cute the way the fanboys stick up for the R5M magazine indexing. I love the single shot Eddies, but the under engineered magazine system on the R5M isn’t up to par with the rest of the gun. And to say we need to “learn” to cock the gun, load the magazine, and insert the magazine is frankly insulting.

Let me ask any owners of FX, Daystate, Cricket, Vulcan, Taipan to name a few. Did you have to “learn” to cock your gun so that the magazine would index properly? Did you have to “learn” to insert the pellets in the magazine to just the right depth, not too little, not too much?

I didn’t think so... When the new R5M design was released I was excited. So very easy to work on, built like a Mack Truck. But the same old faulty magazine system as the R3M. No improvement on a much needed system that could have used some improvement. Just so no one thinks I’m an EDGun hater, I’ve owned and sold two R5Ms and one R5 SM. And I currently own an R3 Long and Lelya gen1. I love them both. But they are single shot Eddies...

I just stumbled across this thread , OK I own all ed guns from r5m to lelya 2.0 in different calibers , and I can say I have never ever had an issue with blowing air in my face , and some of my guns put out up to 100fpe



I never had a jam that was not a slug too large for bore , I have had a few plastic mags break on me though .



to me it sounds like you using maybe too thin an oring to make air leak unless you have a transfer port oring leaking ? I had one oring leak 1 time it is rare .

I know edguns make durable solid guns , but any model made need tweaks .. THe edguns dont have any issues and are very easy to strip down and adjust ,

I would also like to add I also shoot other pcp guns such as , air arms , taipan FX, kaliber ,and a evol now , so on those guns mentioned with a lever base cocking action , some like my taipans can be cocked with my pinky and it is like butter ,

My point is , If I only shot a fx or taipan say they yes I would find a learning curve to get the R5M to be used efficient , It takes a bit of getting used to ,

I say this not for me now because I have hundreds of thousands of shots out of my guns , but when friends try them they some times are not used to say having a 1/1 cocking lever where you need to mustle it and it is normal for this but on a say flimsy platform like say a wild cat if you muscle the cocking lever you bent the cocking bar each gun is good but different , I bet this is what Brian meant

I'm now on my 3rd R5M, a .177 this time and put over 150 shots in 2 days so far and haven't had an issue with any indexing. Never had any issues on my other .22s either 🤨 now I wish it was as nice and smooth as my Taipans have been but oh well. Actually surprisingly one of the best feeling actions with a magazine was a Zbroia Kozak .22. So smooth. 

Also no offense the WORST magazine system to me that I've had experience with is the Kalibrguns. Even with the upgraded DonnyFl plate there just a pain to take out and put in.

Id like to add 1 more thing , I myself prefer the alum mags in the R5M with slugs , when I first get a mag I remove the oring and fit it to my slugs which are sized to barrel then I add 1 oring and it is perfect now for indexing and it is durable as it has more rigidiy it wont break ,

I have had guys come here with edguns they tried loading a larger slug and it get caught half way theyu they couldnt cock it or shut bolt to fire it , , I then simply remove the rear bolt and push out back out breech and then I would show guy the proper size for his gun by checking it ,

I am not sure if some of guys talking about indexing was with slugs or pellets ,

but I always tune my mags for my edguns .to me this is a must

I agree kaliber mag loading is worst out their , but their new gun cricket 2 will be like fx type of mag

Bull butter. I won’t own another EDgun with the current aged and sorry excuse for an indexing system. Done. 

Carry on Fanboys.........👏🏼

Whoa miss some time on the forum and what do I find?!? You are all right. Except that I got blowback to the face even when I held the bolt forward. So that wasn’t it. I got some new o rings and all fixed. Got the gun because of the dependable reputation and the forward cocking levers. Didn’t realize the setup had not been improved. Now knock on wood I don’t have that indexing problem but now I read of the bolt carrier assembly cracking,,, sheesh. Other than that she’s hitting what I aim at like a sledgehammer!
