Q
Tucker, guest, from ME, United States, asked on March 29, 2022

Will it work on a stag 8L?

Expert Answer
A
Answered by Hunter, Gear Expert, from OH, United States, on March 30, 2022

The UTG Pro AR15 Extended Carbine Length Drop-in Quad Rail might work with a Stag Arms 8L. However, the manufacturer doesn't state if the UTG Pro AR15 Extended Carbine Length Drop-in Quad Rail will work with gas piston systems. The handguard at the link below works with most piston systems so it may be a better option.
