Almost 5 stars - Grey Ghost Precision AR-15 M-LOK Handguard

It’s smooth, light, has a good snug fit. However, only have two issues: 1) The seated threading for the tightening bolts were not flush within the handrail. One is slightly protruding. 2) At no fault of OP, USPS lost my package in Dallas, TX and did not move from the facility for 3-4 days. Customer Service was very understanding. Though I did not get the phone call and/or email I was told I’d get, I did receive my order 2 days following the call.
