Sig Sauer MCX Rattler LT 6.75” 300 BLK Conversion Kit In Depth Review & Installation. #2ndamendment
This video provides an in-depth review and installation of the Sig Sauer MCX Rattler LT 6.75” 300 BLK conversion kit. The reviewer covers the upper receiver and installation process. A critical issue encountered during zeroing was a damaged Geissele SSA-E trigger, suggesting the need for a 5lb mil-spec trigger or a Sig AR-15 trigger for proper function. The reviewer concludes by recommending purchasing the complete Sig firearm over the conversion kit due to this compatibility issue. Affiliate links for thread locker and the reviewer's Amazon store are included.
