The IWI Zion Z-25 is a 308 Winchester AR-10 pattern rifle built for the DMR role. It runs an 18" barrel with a nitride finish and threading for suppressor or muzzle device attachment. The 17" free float handguard has M-LOK slots on all sides plus a full length ARCA rail on the bottom, so you can mount a tripod directly without adapter plates. That ARCA integration is a real advantage for precision rifle shooters who work off tripods and barricades in competition or in the field.IWI equipped the Z-25 with a B5 Systems stock on an 8 position buffer tube, giving you solid cheek weld and more length of pull adjustment than a standard 6 position. The upper receiver has a full length Picatinny rail for optic mounting. The lower features an ambidextrous charging handle and standard AR-10 controls. At this price point, getting a factory ARCA rail, B5 furniture, and an 18" barrel from a manufacturer with IWI's track record is hard to beat. The 20 round magazine gives enough capacity for range work and practical shooting stages. This rifle is ready for a scope and suppressor out of the box.
