TM M4A1 Ris

[Cpt. Steele]

Is the handguard cap and delta ring on the regular M4A1 same as the M4A1 RIS. Reason is I found a TM Ris for a very good price, but when I look at WGC the TM M4 RIS includes new handguard cap and some other sites include a new delta ring

The end cap is slightly different from the stock one. However the stock end cap CAN be modified to hold the TM RIS system. All the end cap needs to hold is the lower part of the RAS. Although having the correct cap will greatly help reduce stress on the screws that hold the forward part of the RAS system.


The stock delta ring will secure the TM RAS. The modification to the front cap is needing to increase the diameter of the inside well of the cap. This can be difficult and the end solution I had for my TM RAS was to remove the walls save for the very bottom of the cap so that it would give the lower section something to hold on to. But really the best course of action is securing the proper cap.
