Q
Landon, member, from NE, United States, asked on October 25, 2022

Do I need the 18 or 16 TPI for the Wilson Combat BILLet-AR-10 receiver?

Expert Answer
A
Answered by Hunter, Gear Expert, from OH, United States, on November 02, 2022

Wilson Combat does not state the threads of that upper receiver. From what information I could find you will need the 16TPI model of the Lancer Systems LCH7 Octagon Carbon Fiber Handguards. However, I recommend contacting Wilson Combat to confirm compatibility.
