Adaptive Magwell

The Lancer Adaptive Magwell is a simple, easy-to-install component engineered to significantly reduce reload times for law enforcement officers and soldiers.

With its funnel-like design, the adaptive magwell increases the diameter of the magwell and trigger guard area. The component is designed to fit mil-spec 5.56 AR style rifles with winter trigger guards and requires no tools to install. The adaptive magwell is machined from 6061 T6 aluminum.

The Adaptive Magwell is currently available in two configurations; original two piece version and the NEW one piece upgraded version. Both available now.

Viper Brake

Lancer’s Viper Brake is a “tunable” brake designed for precision shooters. It’s engineered with a blast chamber and four tunable jets to effectively reduce recoil, making for faster follow on shots. Different sized jets are supplied so the operator can tune the downward force. Angled blast baffles reduce recoil, further stabilizing the rifle. Made from stainless steel for .30 and 6.5 caliber rifles utilizing a 5/8-24 thread pitch. Includes a jam nut and six tuning jets.

Nitrous Compensator

The Lancer Nitrous compensator is a “tunable” compensator. Engineered with a blast chamber and tunable jets, the Nitrous compensator will effectively reduce muzzle climb making for faster follow on shots. Angled blast baffles are incorporated to reduce recoil and further stabilize the rifle.

The jets release gas from the blast chamber creating a downward force on the muzzle of the rifle. Different size jets are supplied with the compensator so the operator can customize the downward force, minimizing muzzle climb. Tuning is a simple matter of changing the combination of jets until the desired effect is achieved.

The Nitrous compensator is available in 416 stainless steel or 4142 steel that has been Ferritic Nitrocarburized (BLACKNITRIDE™) and threaded in 1/2×28 for 5.56mm AR’s and 5/8X24 for 7.62mm rifles.


  • Includes two each of the following for tuning:
    • The solid set screw can be used to completely block off the hole or can be drilled to a custom size
    • Orifice jets
  • Supplied with a crush washer
  • Dimensions: Length ‐ 2.88″  Diameter ‐ .99″

Carbon Fiber Stock

Lancer’s Carbon Fiber Stock (LCS) is a lightweight, fixed stock for 5.56mm and 7.62mm AR-style rifles that use a fixed rifle length buffer tube (not included).

  • Carbon fiber tube has a unique layup and resin combination tough enough for hard use
  • Profile provides strength and comfortable cheek weld
  • Injection molded, impact resistant polymer butt plate and front collar
  • Butt plate has a metal quick disconnect insert
  • Buffer tube is not included
  • A2 length includes spacer
  • Dimensions – A1 Length ‐ 10.25”; A2 Length ‐ 10.8”

Shotgun Extension Tube

Applying our experience in carbon fiber product design and lightweight component development, Lancer has created a series of Shotgun Extension Tubes (LSX).  Each LSX is designed to attach to existing shotgun magazine tubes to provide added capacity to the shotgun.  Lancer has combined precision machined aluminum components with an advanced carbon fiber tube to yield a lightweight, durable extension to your shotgun.


  • Available for select 12 GA
  • Adds 2 to 8 extra rounds to the magazine tube
  • An extra‐long spring is provided. The spring will need to be cut to length
  • Shotgun extension clamp is available with or without a Picatinny rail

The LSX is currently available for specific models of Benelli, Remington, Mossberg and Beretta shotguns. More brands and models will be added. Check back for the most up-to-date availability.


Lancer has also developed a unique Shotgun Extension Clamp for use with the LSX. The clamp combines precision aluminum components with a high-temperature silicone foam to ensure a slip-free connection with the carbon fiber tube and shotgun barrel.

  • Made from high-strength anodized aluminum
  • Available with or without Picatinny rail. The rail can be used for accessories or mounting a sling attachment
  • Extension clamps are recommended for extension tubes that extend beyond the end of the barrel. Also recommended for Remington applications due to the shallow threading on the Remington magazine tubes
