TLN Rail
The TLN handguard is the ultimate hybrid of the necessary quad rail and the sleek and lightweight function of the Gen 2 Scorpion rail.

  •  US made- machined here in our Friday Harbor facility,
  • Machined from 6061-T6 aluminum  (one of the strongest, yet lightest hand guard material),   
  • Utilizes a positive dual lock up and 8 screw system that securely isolates your free float rail and keeps it secure,
  • Self indexing, single top rail,
  • Top rail allows the mounting of backup iron sights and laser accessories and provides for co-witnessing using the optics of your choice,   
  • Positive lock to the barrel ensuring added security that it won't come loose under fire,
  • Quick Disconnect sockets  for mission configurable sling positions,
  • Type 3, Class II, anodizing means a tough scratch resistant finish that matches mil-spec upper receivers.
  • I.D. of 1.8" to allow for suppressor inside rail
  • TLN handguards are currently available in lengths of: 7" (6.5oz.), 10" (8.1oz), 12" (10.5oz) and 15" (12.6oz)
