Does this fit models with the bayonet lug? I see conflicting information saying if it’s both with and without banner and some sage us without?

Yes it does. However, you will not be able to use a bayonet with this hand guard.

Will this also fit the Sig 716? Expert Answer

The Midwest Industries SIG 516 Extended Free Float M-LOK Handguard is not compatible with Sig 716 model rifles. I would recommend the Lancer Replacement Handguard for Sig 716 which can be found by using the link below:

great product without breaking the bank by Jamie, Verified Owner, March 24, 2025
Rail is very rigid and lightweight. Love the styling as it almost changes the entire look of the firearm from the stock rail. Fits bayonet lug gasblock and lugless block.

Midwest handgaurd by Jdavis, October 23, 2022
I absolutely love this handgaurd!!! The ergonomics has changed it for the best. Quality is definitely good. Took the factory one off and bolted the new one one very easy. Looks like it belongs once applied.

A great replacement handguard by Deuce, August 30, 2023
The handguard is lighter than the original handguard and makes it look a little more modern. The look and modularity are nice and allow you to still clean the piston easily. Also it fits rifles with the bayonet lug.
