Is this a free floating rail?

A
Answered by Armando R., Gear Expert, from IL, United States, on March 18, 2018

This is not a free floating rail. It is a drop-in handguard for those with fixed, triangle front sights or large gas blocks.

Joe, member, from ID, United States, asked on February 05, 2018

will this product fit the Windom weaponry 300black

Expert Answer
A
Answered by Armando R., Gear Expert, from IL, United States, on March 18, 2018

That will be very dependent on exactly what model of Windham Weaponry AR you have. These are meant for AR's with fixed front sights/railed gas blocks. They are not free floating and are drop in handguards.
