What is a "FEATURELESS" rifle?


"Featureless Rifle" is a term used to describe a California compliant semi-automatic rifle that is devoid of the "features" that would qualify it as a restricted or banned "assault weapon" per section 30515 of the CA Penal Code.


 (a) Notwithstanding Section 30510, “assault weapon” also means any of the following:
(1) A semiautomatic, centerfire rifle that does not have a fixed magazine but has any one of the following:
(A) A pistol grip that protrudes conspicuously beneath the action of the weapon.|
(B) A thumbhole stock.
(C) A folding or telescoping stock.
(D) A grenade launcher or flare launcher.
(E) A flash suppressor.
(F) A forward pistol grip.

(2) A semiautomatic, centerfire rifle that has a fixed magazine with the capacity to accept more than 10 rounds.
(3) A semiautomatic, centerfire rifle that has an overall length of less than 30 inches.

Traditionally, and in common practice, "featureless rifle" is a term that is used to describe a semi-automatic rifle which has been configured using components that do not meet the definition of any of the features described above.  Primarily, a properly configured "featureless rifle" would have a fixed stock, a muzzle device that qualifies as a brake or compensator only (or no muzzle device at all) and a method of gripping the weapon that does not meet the definition of a pistol grip per section 5469 of the CA code of regulations:

11 CCR § 5469

  • 5469. Definitions.

The following definitions apply to terms used in the identification of assault weapons pursuant to Penal Code section 30515:

(a) “Detachable magazine” means any ammunition feeding device that can be removed readily from the firearm with neither disassembly of the firearm action nor use of a tool being required. A bullet or ammunition cartridge is considered a tool. Ammunition feeding device includes any belted or linked ammunition, but does not include clips, en bloc clips, or stripper clips that load cartridges into the magazine.

(b) “Flash suppressor” means any device designed, intended, or that functions to perceptibly reduce or redirect muzzle flash from the shooter's field of vision.

(c) “Forward pistol grip” means a grip that allows for a pistol style grasp forward of the trigger.

(d) “Pistol grip that protrudes conspicuously beneath the action of the weapon” means a grip that allows for a pistol style grasp in which the web of the trigger hand (between the thumb and index finger) can be placed below the top of the exposed portion of the trigger while firing.

(e) “Thumbhole stock” means a stock with a hole that allows the thumb of the trigger hand to penetrate into or through the stock while firing.

The AR15 rifle seen above, equipped with our OPTION ZERO system, is configured in a "featureless" manner. The Butt-Stock is fixed, the grip does not allow a "pistol style" grasp and the muzzle device is a compensator designed solely to reduce the muzzle climb of the rifle.  Although it is a semi-automatic, centerfire rifle with a detachable magazine, it does not have any of the defining features of an "assault weapon" and cannot fall under the restrictions imposed under 30515PC.

"Featureless Rifles" DO NOT require the use of any magazine locking device and DO NOT require registration as an "assault weapon" under current CA law.

The advantages of going "featureless" with our OPTION ZERO system are:

  • The rifle remains completely usable from a practical perspective. You can reload the rifle in a conventional manner, without the need of any tools or disassembly of the action!  this means that your rifle will be, for the first time, a viable self defense weapon.
  • There would be no need to REGISTER your existing rifle as an "assault weapon" (semi-auto rifles, purchased prior to December 31st, 2016 and equipped with a magazine locking device are required to be registered with the state of CA no later than December 31st, 2017).
  • You will be able to legally remove your magazine locking device!  Under the currently proposed regulations, firearms equipped with magazine locking devices (commonly known as bullet buttons) will be required to be registered with the locking devices installed and must retain them even after registration (no modifications will be allowed to the magazine retention systems). 
  • On rifles purchased after January 1st, 2017, going "featureless" will allow you to build a fully functional AR15 that is compliant while being usable in the real world! Remember, any rifles acquired after January 1st, 2017 which have any of the features described above, will require a FIXED magazine, essentially making your rifle a good looking and expensive paperweight.
