After months of trying to get under 4 MOA, I installed the long stabilizer with adjustable gas block on my mini 14. I turned the gas down to a short ejection (4 feet) Optics are vortex diamondback 3x9 tactical.
I shot 110 yards with a 1 inch group using cheap ammo. More than once!!
Holy crap that thing works!!

• Top Pictured Stabilizer II - Long bar length between front of gas block to back of clamp is 3.6", Length to tip of Stabilizer bar is 5.250". For 18.5" barrels.

Accuracy & Benefit Features:

• Forget the Other Struts, Bars & Rods.
• Weighing only 5 ounces and yet very strong.
• 7075 Alloy For it's weight stronger than steel with no cracked gas blocks for the last 10 years. *Use correct torque settings.
• We deliver the best of both worlds featuring the integrated Barrel Stabilizing bar (Strut) for superior Rigidity and the Tunable Gas block for controlling excessive gas pressure.
• This translates into giving you better accuracy and it looks great too!
• The Stabilizing bar screws directly into the face of the gas block giving you a more rigid, more stable integrated connection.
• Available with or without our gas tuning system. (Hence the Name Adjustable Gas Block System)
• Less busy look like others on the market which use two small set screws and an additional clamp to achieve rigidity.
• Our single front clamp securers the Stabilizing bar to the barrel giving the rifle a cleaner less cluttered look.
• A removable sling swivel stud is included.
• Hole pattern matches Ruger's factory Gas block Top & Bottom for aftermarket add on accessories.
• Will fit Amega Ranges, AltiMAK, Ranch Products and Accuracy Systems Scout Mounts.
• Gas Pressure Adjustment screw is located between the barrel and stabilizing bar which protects it from being bumped and still easy to adjust.
• Gas Pressure Adjustment screw does not have the positive Click feature as the Gen 4 gas block however there is a set screw for locking Gas Pressure adjustment Screw in place after the adjustment has been made.
• Comes Complete with Gas block, Gas block Top, Stabilizing bar installed, Gas pressure adjustment screw, set screw, Barrel Clamp, Gas pipe, Swivel stud Installed, & 4 gas block screws.
• Our product is not a guaranteed accuracy fix. There are to many factors that go into making a rifle more accurate. Our product will not help a worn out, shot out, out of spec bore dimension or defective barrel. There are times when a new barrel replacement would be warranted.

WHEN ORDERING PLEASE MAKE SURE OF CORRECT SIZE:

Subject: Fw: Mini-14 Before and After Groups with Accuracy Systems Harmonic Barrel Stabilizer II

Expand the picture and you can see before and after 50-yard 3-shot group results of factory Federal MSR 62 gr. Fusion, Federal 55 gr. FMJ and PPU 62 gr. FMJ loads.
Circled bullet holes are 3-shot 50-yard groups fired off a solid sand bag rest before the gas block and stabilizer was installed.
Un-Circled holes are 3-shot 50-yard groups fired after installation on the same targets with exact same factory loads.
Worked up some loads afterwards that also group 1.4 MOA and a little under.
Ruger factory bushing was .005" too long and took .001" at a time off until the bushing was still snug enough to not allow gas blowby then torqued it to 40 in. lbs.
Thanks for a great product that works as claimed.
I can now shoot it with confidence to not miss or wound.

Forgot this target I'd set aside.
You'll need to expand the picture to see all the groups.
Shot factory ammo groups on the same target with different loads before and after installing the Accuracy Systems Adjustable Gas Block / Harmonic Stabilizer for an accurate comparison.
Groups with bullet holes circled are before and un-circled holes are after installation showing a clear improvement.
Mini-14's combat accuracy is what it is.

Just got my mini14 trigger group back after you guys did your advanced modification. Absolutely amazing improvement over the factory trigger! I didn't think it would be possible for anyone to make such an incredible improvement! Also appreciate the 13 day turnaround time!

Thanks so much!

Tired of hitting the fellow 3 shooting benches down in the head and him throwing the brass back at you?
Tired of having to change gas bushings only to find you didn't get the right diameter installed and had to start the process all over again?

• The BeneFits Of Our Adjustable gas block Systems are:
• Will allow you to save all the lost brass that is ejected normally 20 to 30 feet by your factory gas system.
• Will save your scope as well as your receiver during the violent impact that happens every time you fire a round and the operating rod whacks the receiver.
• Will actually help your rifle shoot better by reducing the harmonics that are produced when the operating rod comes in contact with your receiver during high speed cycling of the operating Rod.
• Can be adjusted from no cycling at all for you single shot bench shooters to wide open for you high capacity magazine junkies who don't care where there brass ends up. But some where in between is best.
• Installation is as easy!
• We offer the Generation 4 the most advanced of our generations of gas blocks with the precise positive click adjusting knob.
• No adjusting wrench needed.
• The Generation 5 for those who already have a Accu-Strut, Har-Bar, Trueshot Technologies, or the Mo-Rod and wants a adjustable gas block.
• All above are available in the .562", .625" and .750" diameter.

• Will not work with the Accu-Strut, Har-Bar or Mo-Rod. Our Generation 5 gas block below will work with Accu-Strut, Har-Bar or Mo-Rod.
• Positive Click no back out adjustment Knob.
• 7075 Alloy For it's weight stronger than steel with no cracked gas blocks for the last 10 years. *Use correct torque settings.
• 1/2 the weight of the factory gas block.
• Cools faster than the factory gas block.
• Not a cast part as the factory gas block.
• Hole pattern matches factory gas block Top & Bottom.
• Will fit our Scout mount bolt pattern.
• Will fit Amega Ranges, AltiMAK Scout Mount & Ranch Products Scout Mount
• Comes complete with Adjusting knob, Gas pipe, Top & Bottom of gas block, Sling Swivel stud, & 4 screws. (You use your gas bushing)
• Testimonial: attention: Carl, I received the new Gen 4 gas block I ordered over the phone from you and must say I love it. I'm still tinkering with the settings but its nice to be able to turn it into a instant bolt action when the brass snatchers are around the range and leave my reloading brass on my table instead of thirty feet away!
