Hello guys n gals! I just got back from the county administration office after filling out the paperwork for starting my new personal business! I am going to start offering custom Ar-15 uppers that will be available in a wide array of anodized colors, but I'm turning to my fellow THR shooters for your advice on a free float handguard. This is in reguards to mounting a bipod onto the handguard. Would you rather have.... a milled slot with a 4" picitinny rail at the 12 oclock position at the front for a bipod adapter, or a conventional bipod sling swivel stud instead? Here's a pic of the handguard in the white. Let me know what you think!
