What makes you think the receiver is different? 🤔
For the record, the basic 716i isn’t even listed on Sig’s website right now - let alone the “specialty” versions. But if you look at the M400 and see the differences in the M400 TREAD Snakebite, they are an upgraded trigger, handguard, and compensator. Most of the Snakebite accessories are cosmetic…I can’t see any reason to expect the 716i would be any different.
