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.
• Middle Pictured Stabilizer II - Medium bar (SOCOM) length between front of gas block to back of clamp is 2.55", Length to tip of Stabilizer bar is 4.250". For 16" barrels.
• Bottom Pictured Stabilizer II - M1A (Style) - Length between front of gas block to back of clamp is 1.7", Length to tip of Stabilizer bar is 3.400". Fits all 16" & 18.5" barrels. Works great for those wanting the M1A look on their Mini 14!!

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 secures 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, Ulti-MAK, 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.

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!

Protection from the harmful battering encountered when the operating rod whacks the front of the receiver. Two piece design use One Or Two for more recoil dampening. Bolt Stays Locked Back on last shot. Pre Fit. Other designs like Buffer tech fit poorly and require fitting. A must for protecting your Scope, Receiver and Factory buffer. Protects receiver also.

When installing our ASI - 2 part buffer system use both buffers together in front of the receiver for maximum buffering. Then check that the rifles bolt will stay open after the last shot. If it does not. Remove one buffer and keep it as a spare. Leave the other buffer in and the bolt should stay open on the last shot. There will still be enough buffering with one buffer to keep the action protected from the harmful battering encountered when the operating rod whacks the front of the receiver.

Reduces the distance your brass is ejected. Reduces battering of your receiver & Optics. Reduces barrel harmonics. Easy Installation. Start with a Middle size bushing.

Manufactured in the USA Please refer to Product instructions tab on our website when installing. Kit Includes .035", .040", .045", and .050". Our bushings will be slightly longer than the factory size to prevent bushing bounce which can damage the bushing. This is due to the factory's bushings being of one size fits all which is not correct because we have found that after measuring the hole depth in hundreds of factory barrels the depths of the hole is inconsistent from barrel to barrel. Our adjusted size is a better overall length so you will not have to trim them 99% of the time. THE LENGTHS DO NOT NEED TO BE TRIMMED FOR THE FACTORY GAS BLOCKS!
