Edgun r5m standard .25 problem

[JWilson]

There is one more issue that I recall. When I shoot the gun, the cocking levers of both sides pop back a bit. But I dont feel any blow of air on my face. I just saw a video of Ed shooting the similar gun and his cocking lever was not popping backwards at all.



This may be one of the reasons of bad accuracy.

Is there any easy fix to this issue?

If the carrier was not forward and locked, you would know it as it will be quite alarming when you pull the trigger. The pop in the ear is unmistakable If the carrier is staying locked, this is not likely the issue. If it is popping... Let’s talk.

The levers lift the lock and allow you to pull the carrier back to cock the gun. They are spring loaded and will move a little on firing the gun. It is not an issue unless there is play in the carrier lock. The play is now eliminated by two springs on the front of the carrier. You can feel the spring play when you push the cocking levers all the way fwd... they move back a little under spring tension. If your gun does not have springs on the front of the carrier I will share a hack fix that is 100% reversible.

Do you know what the first velocity peak is for the gun with this pellet and regulator setting?

Have you confirmed the HST is below the knee of the velocity curve?

Have you tried a different tin of pellets?

Have you tried a different pellet?

Have you verified the alignment of the shroud?

Is the gun stock or has an aftermarket shroud or adapter been added?

Have you talked to your distributor?

Have you installed a different optic to rule out the scope?

Rings and bases tight?

Post a picture of the gun and the groups...

Thank you.

Right now the gun is not with me. I shall inspect it as advised. But I remember that there is no air blow back, only levers move back a bit.

Let's see

The gun is stock. Not modified yet. From the factory it was doing 790 fps with 34 grain jsb mk2 pellets. I tightened the hammer spring and where it stopped increasing fps, I back out the HST a bit. Now it shoots the same 34gr pellets at around 850 fps.

Reg has not been touched neither tested for the factory set pressure.

Only 25 grain and 34gr JSB pellets have been tested.

There may be some issue of alignment of shroud. I would have to inspect.

Once removed the barrel so it might like some different torque on the screw tensioning and holding the barrel .

We have tested it with trusted scopes.

Rings are properly tight.

Pics of groups are not available right now.

Thanks

Can you share why the barrel was removed? Have you suffered accuracy concerns before the barrel removal or did it start after?

Barrel was removed to inspect the barrel as the accuracy issues were from the day one.

If you're shooting 34 grain JSB, most likely it's a tight fit in the chamber. At least with mine it is. I have to make sure to push the cocking lever all the way forward until it locks. If it's not locked, I'll get blowback through the breech area.

check if the barrell and shroud are centered, a friend of mine have one and that was the problem.

Sure I will check this. Thanks
