My adventure continues in getting my gen 2 Mrod .22 working after a double feed disaster.
I just reinstalled new baffles, the shroud spacer, and the o-ring, which were all damaged in a double feed disaster.
I didn't get the shroud spacer on tight enough.
I wound up shooting it, and the pellet clipped, and now I have to replace everything again.
Question: how to get the shroud spacer on all the way? Do I have to take off the barrel off the rifle?
I understand it is a friction fit, but how to get it on without hammering it so hard and warping the barrel?
Thanks in advance for your help.
-
What I've done on it is stick an Allen wrench or screwdriver through the holes in it and twist it back and forth. That's how I take it off and put it back on easily
-
I'm assuming "Shroud spacer" is the STRIPPER that presses onto barrels muzzle ?
Yes, a nail. punch or like tool across 2 opposing holes it twists off.
Reinstalling simple as placing stripper on hard surface facing up, place barrel into the end & with a firm push barrel will slide in and bottom out & should take minor effort with no pounding !!
To remove barrel from Receiver required removing receiver from air tube, pulling out transfer tube and a seal ring, then loosening 2 grub screws on top of receiver ... That done barrel pulls out effortlessly.

Thanks. I'm assuming you can do this without removing the barrel. I don't have a good history of putting things back together.
I figure this should be a simple project, and I won't have to send it back to crosman.

If just wanting stripper on/ off ... easy peezy

Nother question (so this thread won't be my last):
Do you have to degas and depressurization the rifle prior to removing the barrel?
You guys are awesome... thanks.

Just curious why a double feed will damage anything in a marauder. I have double-fed both my marauder rifle and marauder pistol couple times and cleared them all by just firing them. So far I have not noticed any averse effect. Is it something I am not supposed to do?
-
My research told me it's not necessary to empty the air first if you just remove the top action in order to work on the barrel.

Receiver can be removed while tank has pressure

Lordinvincible,
You may get away with a double feed if you are lucky. I probably have in the past. But there is a high chance one or both pellets will tumble and they fly off axis... and then destroy your baffles, shroud spacer, spacer o-ring, and/or end cap.
Once any of the above are destroyed, don't fire again, since more damage occurs.
Some of the higher end guns have anti-double feed features (I think Hassan gladius has this).
-
let's say some baffles,end cap, or air stripper are damaged by some tumbling pellets due to double feed, why would it affect accuracy on subsequent shots? anything past the length of the barrel itself don't do anything at stablizing a pellet once the pellet travels past the barrel. Correct me if I am wrong.
Thanks.

Lordinvincible,
I'm not an expert, but this is my take.
For the double feed, it is more obvious. Even if the first pellet flies straight, in its wake there is turbulent air flow, that destabilized the second, causing it to veer off. Reality is probably more complex. With the second one accelerating and colliding with the first.
If you fire a single pellet after the double feed accident has caused damage, the pellet is actually affected by damaged components upstream. Anyone should correct me, but I believe the rifling of the barrel allows some air to rush past ahead of the pellet. This upstream air is affected by the asymmetry of the damaged baffle, etc, and the pellet is not traveling in still air, but the contrary... turbulent chaotic micro air currents... resulting in it going off axis or veering off and striking another baffle or doing more damage.
I can speak from experience, the pellet might not even leave the endcap.
-
Sounds plausible. I guess i have been lucky so far with no damage. The Prod has no baffles so it shouldn't be a problem but for the rifle I will take out the baffles before double-shooting from now on.
Thanks.
