DefenseReview first reported on the M16 Clinic AR-15/M16/M4/M4A1-platform 5.56x45mm subcarbine/SBR (Short-Barreled Rifle) weapons packages back in December, 2004. That first article discussed the select-fire/full-auto, SOPMOD M4 CQBR (Close Quarters Battle Receiver)-style M16 Viper and M16 Viper-XRP (eXtra-Range/Perimeter) 5.56mm subcarbines/SBRs, which are built specifically for military Special Operations applications, including anti-terrorism/counterterrorism operations. These weapons would appear to be ideally suited for IHR (In-extremis Hostage Rescue) operations, VBSS/MIO (Visit, Board, Search, and Seizure/Maritime Interception Operations), GOPLATS (Gasoline and Oil Platforms) operations, destruction operations, military/PMC/PSC PSD (Personal Security Detail, a.k.a. Personal Security Detachment)/executive protection ops, and LE SWAT ops. They would also seem to be an ideal choice as a long gun/shoulder weapon for law enforcement first responders, as well as an auxilliary weapon (long gun/shoulder weapon) for federal law enforcement personnel that are likely to encounter armed, hostile, and determined subjects/criminals, like those incountered in the infamous 1986 Miami FBI Firefight/Shootout (April 11, 1986), for example. The M16 Viper SBRs/subcarbines are easy to carry/transport, can be concealed under a jacket or over-sized outer shirt, and are highly-suitable for vehicle deployment, due to their relatively compact, lightweight profile/envelope, while still providing the necessary lethality, range, and firepower for urban warfare, CQB/CQC (Close Quarters Battle/Close Quarters Combat), and PSD/executive protection applications.
Well, DefenseReview has received two brand new video clips from the good folks at M16 Clinic. The first video clip features their M16 Viper 5.56 subcarbine/SBR package being fired on full-auto. The second video clip features the M16 Sniper Viper 5.56 rifle/carbine package with Extended Rail being fired in semi-auto and full-auto modes. There are two M16 Sniper Viper variants: Standard model (shorter Mil-Std-1913 rail system/forend rail tube) and Extended Rail model (longer Mil-Std-1913 rail system/forend rail tube).

The M16 Viper weapons packages are custom (custom made, custom-tuned, etc.) drop-on AR15/M16 upper receiver assemblies (as opposed to complete weapons, i.e. lower receiver assemblies included) that “drop on” to your existing lower receiver assembly. The M16 Vipers operate via direct gas impingement, as opposed to the HK416 (Heckler & Koch), P.O.F-USA P-415/P-416 Gas Piston Upper w/C.R.O.S. (Corrosion-Resistant Operating System), and semi-auto-only Colt LE1020 carbine/subcarbine/SBRs, which are all gas-piston-driven/op-rod-driven.
Warning: Watching the video clips (above) may contribute to a common psychological condition known as “Viper Envy”. In the event that this occurs, Defense Review recommends that you contact M16 Clinic immediately by phone at 505-891-0282, or via email at [email protected], as acquiring an M16 Viper variant (weapon or upper receiver assembly) of your own is the only known cure. Ask for Greg Leaf.
