Knights M4 length rail system (not sure if it RIS or RAS attaches to front handguard retainer), slightly used. It was missing the forward mounting screw when I bought it and I have not replaced it. Comes with three 11 rib panels and I have Knights pistol grip I will sell to whoever buys it. Email for pics.
I am looking to trade this towards for a Knights M5 Rifle RAS (P/N: 98065 ) or a Knights MK 12 MOD 1 free-floating RAS long model (P/N: 99266) or $250.00 plus shipping.
1st I'll take it emailed to me at email@example.com gets it.
Thanks for looking.
