Troy MRF 121 free float rails (full length). $130 shipped.
Part of the bottom rail was trimmed to allow the stock end cap to remain inplace (this allows you to go back to stock HG's w/o pulling the gas block depending which cap you have).
New the rail is $230 and includes a swivel stud mounted on the end to permit use of a harris bipod or similar. Slight dimple in one slot next to swivel stud from previous accesory. To install, you will need to remove the barrel nut to remove stock handguard retaining ring. Will throw in 2 FDE (tan) rail covers.
