Tannerite meets Accuracy Systems Ruger Mini 14

Thought you guys might enjoy this.
I was at a ranch in Eastern Oregon last month and our host put some Tannerite in a 1-inch pipe beneath a (spent) propane tank 75 yards away. He told me I had 20 chances to hit the one-inch-diameter target.
This was my first shot.
Thanks again for your excellent work on my rifle.

custom remington 700 6.5 x 284 1/4 MOA three shot group custom remington 700 6.5 x 284 1/4 MOA three shot group


I pulled the first shot, but the last 3 as you can see below show what the rifle is truly capable of doing. You may not the be the best known custom Remington 700 gunsmith, but I will take this accuracy any day. Had another guy shoot it when I first got it and his first question after shooting it out to 1000 yards was “Who built this rifle.” He is a very good shot and has shot many different custom rifles. He was very impressed with the quality and accuracy of your build. He was able to hit 5 head shots at 1000 yards "8 inch circle" with it.

Your friend and customer for life.

Hi Carl.

Here is some photo's I have of the AR 10 upper you did for me. One of the Uppers you see if the 6.5 x 284 Norma that you see with the open port that shows a 125 grain Nosler partition bullet ready to be chambered. The 125 grain bullet is exactly seated perfectly in the cartridge, it's not seated deep, the bullet is just right in the cartridge. All of the photo's you can see loaded ammunition in the magazine, these are 6.5 x 284 Norma loaded ammunition with Nosler partition 125 grain bullets which seat exactly perfect without the tail of the bullets seated into the cartridge case space with the powder. The base of the bullet is at the bottom of the neck of the cartridge.

The other upper in 6 mm x 284 was a perfect match for the AR 10 because 24 caliber bullets are short so they can be seated out or seated to where ever you want the bullets seated in the cartridge . The attached photo of me with the Trump shirt, this is the AR 10 with the 6 mm x 284 win chambered upper.

Using the 284 win necked up or down is a perfect match to the AR 10, no alterations to the upper or lower or magazines is needed. I did find for magazines I had to use the steel 20 round magazines due to the 284 cartridge is larger diameter than 308, so for some reason the 284 cartridge wanted to only work consistently in the steel magazines. Using any brand of plastic magazines does not work at all loading 284 sized cartridges in plastic magazines.

I will in the future make some more photo's for you .

Subj: RE Adjustable Harmonic Barrel Stabilizer II

Dear Carl

I received the stabilizer last Friday and installed it to my 188 Mini 14 straight away. I went to the range a day later and shot some 100 bullets. The groups at 50m (55 Yards) went from an abysmal 15 cm (6 Inches) down to arround 2.5 cm (1 Inch), no matter how hot the rifle got. Without your stabilizer I would have sold my Mini...

Thanks again for your help and your fantastic product!

Best regards from Germany

Subj: great work


I got back my trigger group from you today after your basic trigger job was done on it. Best 2 stage trigger I've ever used. Smooth trigger release, just the right weight for me. I finished putting the adjustable gas block on about an hour ago. The bushing needed quite a bit of shortening, but I was cautious and your clear instructions were excellent. It's still pretty cold up here in southcentral Alaska, but I can't wait to go shoot my 581 series Mini-14. I know just these basic changes will help make it all the Mini it can be, but ultimately, I will get the three point stock mounting system done and probably the barrel re-crowned.
Thank you so much for your help and expertise. I put a post up on your Facebook page.

Warmest Regards,

Mini-14 adjustable gas block Harmonic Barrel Stabilizer II

Carl, I figured out what was wrong with my set screw. Looks like it had a small amount of thread locker inside the top. Once I knocked that out of the way my .050 worked great. Thanks for the feedback today. So far your gas block has been great and had made target shooting more comfortable and accurate. It's a great product.

Subj: Re: 6x45

Yes. Since the 6.8spc mini 14 is harder to get and my wife and Daughter already have them I bought it. So it gets put ahead of the 6x45 I plan to have you customize for me. So 6.8 first then 6x45. The 6.8 has become a family thing. I may just have to get one for each of my sons. We will see. Hopefully you will be around for many years. I wish you could see the 4shot group I shot at 500yrds with one of the 6x45 you guys put together. Its right at 1.5in! That's four consecutive shots and I had a friend check each shot after it was fired! Just to be sure that it wasn't a fluke I shot two at another target and the bullets were an inch apart. I have a picture of it on my cell phone but i am to computer ignorant to be able to send it to email. I love the work you guys do! Thanks Jay.

Subj: I Love my Mini Again!

Dear Accuracy Systems, Inc.

Just a note of thanks for offering the gas bushings for the Ruger mini's.

My 583 series Ranch Rifle was throwing empties into a different time zone and leaving them unusable for reloading.

I installed the .045" bushing and it is laying them 6 feet away each and every time. Tested it with three different cartridge manufacturers and each functions flawlessly.

Much less recoil and now I don't worry about landing hot brass on strangers at the range. (beyond 6 feet at least).

Again thank you for offering these upgrades for the Ruger Mini. Fast transaction and shipping. Great communications!

I'll be back and I'll be telling others about your site.

Best Regards,

Craig Vuccola

Subj: My Mini 14

The Mini 14 custom rifle arrived last Friday. I apologize for not contacting you sooner. I am very pleased with the work you guys did. I have yet to get the scope accurately set up and take it out to shoot. I have been putting in extra hours at work, so once I get a free weekend I'll take it to the range. I just need to get a couple of cans of the brake cleaner needed in the break in process. Thanks again for the good work. Bruce
Subj: Re: Mini-30 Gas block question/concern.

Thank you for the reply. I completely understand your explanation. Makes sense to me! I can't say enough about your products. I work in a manufacturing plant for surveying equipment and we h e 9 cnc booths- your quality is top no h and well made. My 582 mini-30 now shoots sub MOA.
Keep up the good work!

Thank you.

Subject: Re: Mini-30 Gas block question/concern.

Hello, This area is under extremely high pressure. It will bleed off around the screw which can be wiped off after shooting your rifle. The thread tolerance is correct because that is a high carbon area, If it was any tighter the screw would seize up over time from carbon build up. The way it is designed allows it to clean it self. I hope this explains you area of concern adequately. Thank you, Carl Emmite President of Accuracy Systems, Inc.

I finally got a scope on it ( Mueller 8-32x44 Side Focus MIL DOT), and did some shooting at the Van Wert gun club this morning before the wind picked up. I was shooting Hornady Varmint express 55 grain Vmax at 200 yards off a bench with front rest. Best 5 shot group can be covered with a quarter. Yes, I'm happy, Thanks

Generation 4 Adjustable gas block.

I just wanted to follow up on the purchase of your G4-625NKL gas block order #1169. I recently purchased a new Ruger 5458 Mini-30. and installed your gas block on it. I also installed it on a butler creek folding stock with an AIM scope on the rail that comes with the rifle. Lastly I put a buffer pad on the charging handle/slide group. I set up the gas block as you described in your instructions. I was shooting brass cased ammo. At first all I could get was FTE. I noticed impact marks on the scope ring and moved the rings forward a notch. It still had a hard time extracting. I found marks on the bottom of the slide. It turns out I had an obstruction in the fore-grip of the stock. Once I got all my problems sorted out it was amazing. You could adjust it down so it would drop the brass right at your feet. Or you could close it off and make it almost a manual bolt action. Unless you want to throw hot brass in your buddies boot, I can't see why you would set it to maximum flow. The adjustment knob was close but moved freely. The tight fit against the barrel should help protect it. Over all I think this is a good deal for any Mini 14-30 shooter. With the quality and functionality of this product, I'd say you weren't asking enough for it.
Thank you,

Subj: Advanced trigger job


First, I would like to thank you for the work that you performed on my Mini 14 Tactical last year. I finally got a chance to take it to the range today and am very happy with all of the improvements. Now my Mini is a keeper!

In the meantime, I have acquired another (used) Mini 14 and I would like to send in the trigger assembly for an advanced trigger job. I would just like to confirm that I can send it to you now. I understand the price is $113.99 + shipping, insurance, etc. I can pay on my credit card when the work is complete and you call?

Please just confirm I have it right, I get it in the mail to you! Thanks again for the great job on my Mini Tactical.

Received rifle in perfect condition. Shot rifle this weekend and am very, very happy with the upgrades. It is smoother, less recoil and more accurate. I can hit an 8" target at 130 yards with only iron sights now: before I had to use a scope. I can't thank you guys enough ! My mini 14 is my favorite gun once again. Excellent work !! Will refer all my other shooting friends to you for custom gunsmithing.

Hello Carl:

I just want to say the trigger job you recently performed on my Mini-14 was great. Creep and grittiness are gone, a light pull, bang, and a real short reset. What's not to like? I got the trigger back last Friday and got to the range the next day. A very satisfied customer.
