Product Description

Full launch Spring 2026

The only adjustable gas block for the IWI Galil Ace Gen1! The Pro2.0 ACE FS Gas Block has been precision engineered to address the very real need to regulate the gas on the Galil Ace rifles and pistols, for both reliable tuned shooting and rugged suppressor use, with the integrated Front Sight to match the Gen1 vibes. The Front sight is an AR post, easily adjusted and customizable with many aftermarket front post options.

In collaboration with Occam Defense, the billet adjustable gas block is specifically designed to be compatible with all caliber and barrel length Galil ACE platforms. Rather than using the usual set screw, this design utilizes a gas cup with multiple aperture sizes around the rim. This cup, combined with a detent, allows the user to select between discrete sizes. The gas cup design borrows heavily from historically rugged designs from HK, SIG, AK-12, and FN. Using this design allows the shooter to adjust gas settings from the front of the hand guard without any disassembly of the firearm. As all gas blocks accumulate carbon, we've designed in a removal feature so that the cup can be removed from the front by rotating to the section of cutout flange, and pulling towards the muzzle end of the barrel for easy maintenance. Because this is a fixed design, there are no parts on the block or cup that will wear out with use and cause a failure.

Features: These are 5 Position, externally adjustable gas block for the Gen 1 the Galil ACE Pistols and Rifles in all calibers. You can choose to have the gas valve pre-tuned for your rifle (generic caliber and barrel length with factory ammo), or if you are handy you can purchase it as DIY tune kit with the gas valve locations pre drilled for pilot holes only.

Tune Configurations: We offer 2 different tune configurations for the 5 gas settings on the cup, based on the primary role you see for your Galil ACE. General, will be the most well rounded use, where 2 settings will be dedicated with smaller ports to use with suppressors, and the other 3 settings will be your low/mid/high to use without a suppressor. Competition, is for a gun that will rarely or never see a suppressor, and you want to have more finer adjustments between the 5 settings. Note, using a suppressor with this option may be slightly over gassed, but nothing like the factory block.

Install: Being very easy to install yourself, what makes this a chore is the removal of the factory block. It is advised to have a good set of punches, and a shop press for removal of the factory block, or carefully cut it off with a cutoff tool to make it easy to press off. If you don't want the headache, we can install it for you. Choosing this option, the price increase covers shipping to us, the install and tune, and return shipping. We will send you a pre-paid UPS label and a copy of our FFL to send the gun directly to us, and upon completing the work we return it directly to you. No need to go through an FFL on your end since this service falls under gunsmithing.

If you pair your install with some awesome cerakote of $200 or more, we will comp the install fee (just not the shipping).
