Your WelcomeThanks for clearing that up.
So is the Canadian slotted #11 the same as the Australian?My collection of Canadian Gas Regulators..
Thanks. I have a regulator that I bought from one of our Canadian members that is basically identical to an Australian regulator and was wondering about any subtle differences.Yes, the Canadian C1A1 gas regulator (#11 setting refers to the maximum opening) is mechanically and dimensionally interchangeable with the Australian L1A1 gas regulator. Both are "inch pattern" FAL components, designed for interchangeability within Commonwealth militaries.
The C1A1 and L1A1 rifles were developed under a Commonwealth agreement that mandated the interchangeability of major assemblies and components, despite minor manufacturing differences and the use of British imperial units in their production.
While minor cosmetic variations or different materials (e.g., specific types of wood furniture or finish details) might exist between Canadian and Australian parts, the critical mechanical dimensions, including the gas system components like the regulator, were designed to be compatible across the British, Australian, and Canadian variants.
Therefore, a slotted #11 gas regulator from a Canadian C1A1 can be used on an Australian L1A1 (which also uses a #11 setting on its regulator to indicate the fully open position for the gas port) and function correctly.
Wish I knew sombody in canada. They still sell parts at auctions there but they won't ship to USA. Even stupid little stuff like regulators. I'm not sure why not. I understand receivers n guns gotta be imported but why would small parts be regulated like that ? Or maybe they just playing it safe.
The Canadian C1 and C1A1 rifles used an 11-position gas regulator marked up to 11, which is commonly referred to as the #12 regulator setting.
The C1A1 is an inch-pattern variant of the FN FAL rifle and the gas regulator is a key distinguishing feature from other metric-pattern FALs. The various settings allowed the gas system to be finely tuned based on ammunition type and fouling conditions.
- The standard setting for normal firing conditions was typically lower on the regulator (e.g., around 4 or 5), which utilized most of the gas for the operating mechanism.
- The "12" position effectively vents all or nearly all gas out of the system, preventing the rifle from cycling and turning it into a straight-pull, single-shot weapon. This setting was often used for grenade launching or specific match shooting to eliminate action movement that could affect accuracy.
the gas plug is the SOP for grenades. Your point brings up a good question, why even have a setting that trends toward, but does not eliminate, gas flow?We were taught to reverse the gas plug when firing grenades... (Canadian here).
Not sure if it is written in any book.
I am curious to know what the original design intent was.
Regular is fine, think only the last production ones had the removable ears gas blocks…If I do this on an inch cut receiver, with the stripper clip cover and put the thumb notch. Is it wrong if I have a regular gas block? I don't have the removable sight ear gas block.
