A few questions about Magpul PTS RM4 ERG

[forumslv]

Hi there,

I have a Magpul PTS RM4 ERG  with the recoil. I have attached picture with numbers to better explain the problem.

Number 1 and 2 what are the part names for that part? Mine is broken (next to the rail, glued with the super glue now, so I can use the hand grip) and the current one is the plastic, any ideas where to buy online?

Number 3. Is there any way how to fix, so isn't wobbling? How do I fix it and what should I get for that? Maybe if I get new number 1 and 2 then it would stop?

Regards

Good luck with trying to stop an M4 wobbling.

Most airsoft guns have problems by design. M4's is the wobbling. Things can wobble are front sight, outer barrel, front grip, upper receiver, stock tube, stock, hopup unit, inner barrel, magazine.

Other guns have other problems so there is no best choice really.

Click to shrink...

All of which can be fixed, if you have the patience, tools and the skills to use them.

Failing that, super glue, duct tape, Gripfill and cable ties. Go for the ghetto look...

Let's say if I get lower, upper handguard and barrel nut, would that fix the wobbling ?

If you take off the hand guards you should see the barrel nut inside the collar (3)

Make sure the nut is tight as they can come loose.

If it's a rotational type wobble (if you shoulder the rifle and hold the vertical grip, you can twist it from side to side) then either the barrel nut or the delta ring (the ridged collar around the outside) is a bit loose or it could just be the above mentioned poor design. Even if the barrel nut is tight there will always be a bit of wobble unless you change it for a free floating type handguard that is securely bolted to the front end of the receiver.
