A reticle of a projectile weapon aiming system such as a riflescope includes a primary aiming mark adapted to be sighted-in at a first selected range and further includes a plurality of secondary aiming marks spaced apart below the primary aiming mark. The secondary aiming marks are positioned to compensate for ballistic drop at preselected incremental ranges beyond the first selected range, for a selected group of ammunition having similar ballistic characteristics. Angles subtended by adjacent aiming marks of the reticle can be adjusted by changing the optical power of the riflescope, to thereby compensate for ballistic characteristics of different ammunition. In some embodiments, the reticle includes a set of windage aiming marks spaced apart along at least one secondary horizontal axis intersecting a selected one of the secondary aiming marks, to facilitate compensation for the effect of crosswinds on the trajectory of the projectile.

Existing floating handguards have the problem of adding size and weight to M16 style gas operated rifles because these tubular handguards attach to a relatively large diametral surface which lies outward of a firearm operating member or gas tube. Existing handguards are mounted thus so that the handguard inside surface will mechanically clear the gas tube. The present invention solves this problem by providing a handguard system integrated to a firearm, the system having a one-piece extended barrel nut with a smaller diameter outer surface configured to lie inward of the gas tube, between the gas tube and the barrel. A one-piece generally tubular handguard has an outer surface with a longitudinal rib and an inner surface with an inner diameter and a groove which is aligned with the rib. The handguard inner diameter engages the barrel nut outer surface and the groove provides clearance for the gas tube. The rib is configured to maintain the rigidity of the handguard adjacent the groove.
