The tactical handguard's slim octagonal profile sports a full-length MIL-STD 1913 12 o'clock rail for sights and accessories. The adjustable gas block allows the user to tune the rifle for their preferred ammunition and/or suppressor use. Like all tactical series rifles it comes standard with Magpul MBUS flip-up sights.
