Accuracy Systems Mini 14 & 30 Adjustable & Non-Adjustable Gas Blocks

Harmonic Barrel Stabilizer II with Adjustable Gas Block & Stabilizing Bar (Strut)

"The Most Advanced Way to Accurize your rifle other than replacing the barrel."

4/10/2019
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!!

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!
