Unfortunately the receiver of the Rattler is a bit shorter in length than the standard MCX guns so it will not fit.
No it will not work.
No it will not.
Yes, it should.
It depends on the model, some of these are the factory squared handguards that do not fit suppressors, the models with "SD" in the last couple sections of the product code are wider models that fit suppressors.
No, this is only for the MCX.
Sig does not list the weight of these handguards, please contact them directly for more information.
That depends on which of the two models you are speaking of. The " standard " model handguard has a ID of 1.45" so that is a no go and that is the one that typically comes on your MCX Virtus Rilfe
The "suppressor compatible " model has a ID of slightly under 2". I can not think of a popular production suppressor that will not fit. Sig has one of the larger OD suppressors @ 1.75" for both the 7.62Ti and 338 Ti Series and they fit easily with room. Even the monstrous AAC Titan Series with a OD of 1.85" for 338LM will fit under it.
Yes, it should.
No, these are only for the Virtus models.
