Phase 5 Weapon Systems Inc. is excited to announce the release of our new LPSNx Quad Rail lineup. The LPSNx Quad Rails were developed as an improvement to the original LPSN quad rail. This rail was inspired by lots of beneficial features that shooters have requested and demanded from us and other manufacturers.

The slender design, longer nose, ease of installation and superior construction are some of the features that we designed into this system.

The LPSNx undergoes a rigorous extra de-burring process to ensure a smoother, snag free finish. The details and level of care during the manufacturing of the LPSNx make it the perfect choice for your Carbine or Rifle build.

New Release - Flash Can 1/2x28 and Flash Can 5/8x24


Phase 5 Weapon Systems Inc. is excited to announce the release of two new muzzle devices. The Phase 5 Flash Can is designed to direct gases, sound, and flash away from the shooter and adds a unique, stylish look to your rifle or pistol. Forcing the muzzle blast down-range will enhance your, and your range neighbor’s, experience when shooting a short barrel rifle or AR pistol and is very helpful when shooting at night or indoors. A Flash Can will not reduce felt recoil and will not reduce flash signature. The Phase 5 Hex design gives the Flash Can the perfect styling that custom gun builders are looking for.

NEW Extended Bolt Release Version 3 (EBR v3)


Extended compatibility

The Extended Bolt Release Version 3 (EBR v3) was designed to be compatible with all mil spec AR-15/M16 receiver sets as well as many billet, side charging, and even left-handed weapons.

The EBRv3 gives the operator the ability to reload quicker, clear jams more efficiently, and eliminates unnecessary hand movements during some operations by extending the lever into the trigger well for access on the right side of the weapon.

Like its predecessors, this is a one-piece replacement part for the mil spec bolt catch found in all AR-15/M16 lower parts kits and is a great upgrade for both right and left-handed shooters. The Phase 5 Extended Bolt Releases are depended on, and trusted by, tactical trainers and Law Enforcement officers worldwide.

Built on the legacy of the patented monolithic EBRv2 and EBRv2-SC levers, the Extended Bolt Release Version 3 (EBR v3) was designed with several upgrades:


  • Heat treated, 8620 high strength carbon steel, same as a mil spec bolt catch
  • Secure patented monolithic design, direct replacement component, no screws to come loose
  • Low profile bolt catch, fits many aftermarket billet upper receivers and most side charging upper receivers
  • Grip serrations added to elbow and end of Extended Bolt Release lever
  • Improved magazine follower catch
  • Larger index finger tab for bolt release


The EBRv3 is specially designed to be compatible with a wide variety of side-charging upper receivers.

The EBRv3 is compatible with nearly all AR-15/M16 platform rifles and pistols. This includes many side charging upper receivers, and billet receivers that cannot accept a bolt-on Extended Bolt Release. In general, if the weapon accepts a mil spec bolt catch, the EBRv3 will be compatible.
