CA M15A4 SPC - RIS Wobble?

[fatillac]

I had just recieved my M15A4 SPC last week and promptly attached a vert grip onto the bottom rail.

In taking it out to its first game last Sunday, I noticed that there is some play in the RIS and I can wiggle it side to side.( a fair bit )

I tried tightening it with the delta ring ( both CW and CCW ) and it just spins I am wondering if the delta ring is just for looks?

Anyone know how to tighten the RIS down to stop this? Or anyone have a link that explains the tear down of this gun?

Also, how can I remove the RIS/Front Sling Mount to install the handguards
(They wont go on from the front )

Thanks

i've got the same problem

there's a slight wobble in my RIS system

i've disassembled and reassembled the RIS part and tried to make it work but to no avail

any help?

The spring that pushes the delta ring may be sitting improperly.

Mine is very tight, no wooble at all. Don't know what could help sorry.
