Having trouble putting on a RIS

[Skladfin]

I've got a TM M4A1, and have just ordered CNC RIS from huang, and I can't seem to fit it in.

Here's the CNC RIS

Thanks in advance

It took me an hour with a Dremel, a file and a replacement delta ring to fit that on an ICS, and it's the same basic design as a Marui.

And the RIS wobbles still and requires a barrel nut system like a real one to work, not the crappy Marui/ICS design.

I bought the same one for my G&P and had to file down the upper part of the RIS to get the delta ring to fit over properly, the bottom section fit just fine.

It was just a matter of taking down the diameter a bit, I just kept test fitting and removing material where necessary, it now fits very well with no wobble.

so there is no way that I can just fit it without mods?

Thanks

Almost every RIS/RAS I have ever had to install has required at least a few minutes of dremelling. Airsoft and real ones. None mate perfectly with Marui bodies (Or G&P metal ones either)

Damn!

I put a real steel ICS FIRSH on one of my ICS M4's. I had to dremel the threads on the receiver down a ton, and still wound up putting the receiver in the freezer and the FIRSH lock ring in the oven to get the damned thing to fit. The end result is one hell of a solid RIS. No wobble at all.

I see... I should have known =(
