Which Acc System stabilizer

I have a Mini 14 with the 18.5 barrel and I am going to purchase a Accuracy System stabilizer II. There are 3 sizes. Does one of the three lengths do a better job as a stabilizer or is it an ascetics thing.

I got a True Shot Technology 5.5" stabilizer the first two pics are of 55gn fmj and the last two are 69gn SMK this is at 50 yards with barrel to hit to touch. I will say the added benefits are that it cools the barrel very quickly because its aluminum along with the ultimately rail and it's about half of what a accu strut is $59 shipped to my door. I also included a pic of my 583

The ASI strut attaches directly to the gas block as I recall via a screw that goes directly into the gas block. It looks like a solid system. I believe the Har Bar and the Accu Strut attach to the gas block via set screws.

Every person has their own preference. You did not say which barrel you had. The skinny barrel or the tapered barrel. I don't know that a taper barrel needs a strut but it will aid in cooling. I'm not sure you would need the longer version with the taped barrel if you go with the ASI strut. I would have to think any strut will help with cooling the barrel and gas block as long as you are not magazine dumping.

Which Acc System stabilizer

The rifle is a Ranch Rifle with a sn. prefix of 188.

The barrel at the gas block is .562 and just ahead of a shiny ring it measures .571 and after the ring .564.
I guess I would call it a skinny barrel because it only varies a few thousandths.

The ASI struts have a nice attachment at the gas block, but they run more than double what an Accustrut goes for. You'd better have deep pockets if you buy anything from them (other than gas bushings, those are the only thing they sell that's reasonable priced).

The True Shot might be cheapest, but honestly those clamps look goofy. Way too big and blocky, like everything he makes. On top of that, the maker is a real sanctimonious jerk every time he posts here.

I will only buy the Accustrut, the first and original strut. Looks like it came from the factory, not like something cobbled together by Billy Bob in his garage.
Do the "dimple option" as recommended, and the Accustrut will be connected as effectively as the ASI, and save you $100 over what the ASI will cost.

Accu-Strut will be the one I buy. I’ll support the original, not a knockoff copy.

Thanks for all the replies.
How easy is it to change gas bushings with an Accustrut on the barrel and the dimple to the gas block?
Do you have to remove the Accustrut for this? It looks like you would have to remove it.

Changing bushings is still easy with a strut attached, you just have to loosen the clamp (or clamps) enough to swing the lower gas block down a bit, enough to swap out the bushing.

fa 38, how far is your brass going ? My early model Minis didn't throw brass near as far as the later models. I had no need to change the bushing.

With my old P Dog loads, loaded in either 1987 or 88 they fly probably 50 feet. If the range did not have a roof I don’t know how far they would go.

The load was 748 powder and either 50 grain SX or Blitz bullets.
They would not go into the Mini or my Model 70 Sporter Varmint as they were loaded originally just neck sized for my Rem 700 Varmints. I reworked a full length die so that the neck and bullet were not sized and would stick out above the die.

Accuracy after just full length sizing the body and shoulder of the loaded ammo was about 8 to 9 inches for 8 shots at 100 yards. I then tried seating the bullets a bit deeper in the case and the groups went down to around 3.5 inches at 100 yards 8 shots. I have over 1500 of them left.

So I am probably going to get a Accurstrut and one of Accuracy systems adjustable gas blocks. I plan on trying to work up some cast bullet loads for the Mini that would cycle the action. The strut and gas block would also probably help with my old dog loads and any other jacketed loads I can come up with for all my odd boxes of bullets.

I looked at the targets again and realized I only had 8 shots on each. This was back in early Nov. and it was getting so darn cold and has stayed that way. I will wait for some warmer weather to try any mods.

fa38, I would suggest shooting your skinny-barreled mini first as-is to decide if you even need a barrel strut. From your pics, it looks like your Mini has been chopped to 16.1" - which would solve a LOT of barrel whip. That seems to be a "golden length" for the skinny barrels with certain standard ammo (5.56 M193).

It is not a sniper rifle! Consider 2 MOA great, less than that even greater. But it is a carbine. Keep it light weight if you can.

Should you go for an Accustrut, go with the SOCOM model (one clamp) if your barrel is 16.1".

All IMHO, of course...

If I measured right its 18 3/8 from the muzzle to just short of the front receiver ring. The rear of the barrel is just forward of the rear of the ring.

50 feet. Yes, you need a reduced gas bushing or an adjustable gas block. If you do the adjustable gas block it's just a short walk to the added strut.

I am going stir crazy with this cold weather so on the milder days I have been trying some cast bullet loads at 50 yards and have one that shoots into less than an inch for 5 shots. Have not gone back to confirm the load. The op rod barely moves with the cast loads. The rings are .75 apart. The loads are .2 grains apart. 1st bottom left, 2nd top center, 3rd below 25 ring, 4th bottom right being the heaviest load at 4.0 grains of Win 231 and a 59 grain plain base flat nose.

Cast bullets in a Mini can cause gas port problems, it will take some time and is not hard to fix, shows up as under gassed. The smaller the bushing the sooner it will show up. Just a cautionary note if you shoot a lot of cast stuff.

^^^ What he said^^^.
I can think of a lot of guns where cast bullets are a good choice, and a Mini isn't one of them.

And as I understand it cast bullets are a no no with all gas operated platforms...correct?

Follow up question...

Are hardcast bullets also a no no, or are they acceptable? I suppose the harder material might perhaps slow the process, but still eventually shave/melt off enough material to plug a gas port?

As you infer hard cast with a gas check will stop the gas vaporizing the rear of the bullet
the gas port shaving will still be a problem. All cast bullets are problematic in semi-autos in one form or another. Gas checks will slow the process tho.

Another problem I encountered I purchased a Taurus 8 shot large frame revolver with a 6.5 inch ported barrel. Very nice gun and a good shooter. Previous owner only used lead bullets the ports were plugged solid. Small butane torch and many hours latter I finally cleared the ports. Another reason not to shoot lead thru anything with ports.

You can get away with things that are not recommended provided you are willing to do extra maintenance.
If you must shoot cast bullets out of a Mini or some other weapon with gas operation, be ready to clean the gas port out regularly.

I had a Glock 10mm for a dozen years, and reloaded a lot for it. Some jacketed, but a lot of cast. Yes, you aren't supposed to shoot lead in the polygonal rifling of a Glock, but I never had any problems, Because I cleaned any traces of lead out every 100-150 rounds.
Keep shooting lead and neglect the cleaning, and you'd have problems.

I shoot nothing but cast bullets in my Marlin levers and my single action revolvers, but shooting lead out of a Mini is not something I'd even consider.
Can it be done ? I guess so, but lead bullets and/or reduced loads are something I'd save for the manually operated rifles.

With the price of .223REM and 5.56 M19e and M855 ammo, I can't see the benefit of hand-loading this caliber. Then again, I don't hand-load at all, and part of that is the cost-benefit for the calibers I choose to shoot. Were I to consider 45-70 or something else, I might reconsider, but standard ammo: I'm good with bulk purchases of factory-made ammo.

Not likely to change, as 2-4 MOA serves my interests just fine. Not worth it to me - PERSONALLY - to go further. After all, I have horses demanding their specialized feed and scooping of poop...

I have run over 450 rounds of cast through my Mini 14 so far cleaning it occasionally. Accuracy at 100 yards is not good. At 25 to 50 yards it will serve well as a small game rifle with a much reduced sound signature.

As for shooting cast and screwing up the gas block so that you must take the rifle down to clean it to get it to function, not true, at least mine not true. I shot it for 200 rounds by empty case count and the first shot of a full jacketed load the case ejected but did not pick up the next round from the magazine. At the second shot the rifle functioned normally. I will take it apart and clean all the lube powder fouling out.

I am satisfied that it works well but the real drawback is the scope settings between cast and jacketed. So it is a rifle that I will us with one or the other or with 2 scopes.

Thanks for all the replies.
