About
What it is, and why it matters
The Noveske N6 Switchblock is a premium American semi-automatic battle rifle chambered in 7.62x51mm NATO (.308 Winchester) built on the AR-10 / DPMS pattern. Its defining feature is the Noveske Micro Switchblock adjustable gas block, pinned to a serialized 416R stainless match barrel, offering three settings (Unsuppressed, OFF, and Suppressed) to tune the firing impulse and reliably cycle under adverse or suppressed conditions. The rifle pairs precision-machined 7075-T6 billet receivers with a free-floating NSR M-LOK handguard, a Geissele two-stage trigger, and B5 Systems furniture, and is offered in 12.5", 16", and 18" barrel lengths.
Noveske Rifleworks was founded by John Noveske in Grants Pass, Oregon, and built its reputation on match-grade AR barrels and rifles. The Switchblock, an adjustable gas block toggling between unsuppressed, off, and suppressed states, became one of the company's signature features for shooters running suppressors.
Offered across Gen III and Gen 4 N6 lines in Recon, Leonidas, and SPR configurations. The 18" SPR weighs about 9.6 lbs dry with roughly a 38" overall length and ships with a 20-round Magpul PMAG.
