I have a 184 series s/s mini-14 with a std barrel, the only mod to it being a 250mm long silencer on the end (475grams). At 100m the first shot hits approx 150mm high and 50mm to the left, the next couple a gnats dick to the right and a little high, and the remaining will all group around 50mm about the bulls eye. Havent tried it without the silencer cos its loud and scarey..... Is this to be expected (the movement not the noise) or a clue to an alternative problem. Once the barrel is cool I can do it again and again and its almost a carbon copy. One of the gas block screws broke when the silencer was being fitted so I had the lot replaced, figured if one breaks the others probably arent far behind, could they be to tight? Too much weight on the nose? Only allowed 5 round mags in this country so they all need to count !! Photos to follow when (if) I get ahold of a digi camera...

Welcome doonnzl. When I saw all those m's, and mm,s I figured you must be from across the pond somewhere, what country, if you don't mind me asking? Your laws allow silencers, but only a 5 rd mag?
If I'm reading the mm's correctly, the 150mm dimension is aprox. 6 inches.
Most guns have a wake up, or foul shot or two to stabilize the harmonics in the barrel. The hunter will know how his cold shot will impact, because this may be the only one he gets, but I'm talking maby an inch (25.4mm) or less, not 6"! How is your silencer attached, can you shoot with it off? (wear hearing protection). I'm thinking alignment, not weight, as most of our mini's have a muzzle brake on the end of the barrel. If your silencer has a near similar inside bore diameter, it could be misaligned. The other posibility, the gas block screws should not be squeeking tight, only snug, 17 to 25 in-lbs ( loctite threads), and the gas block halves need to be gaped evenly all way around. Mine was about .023". If it is too tight, or not torqued evenly then it will compress the bore. If the screw broke that is way, way too tight!!! Give these ideas a try, and let us know what you find. Again welcome to our forum.

My guess is "down under" - the land of rugby, yachting, sheep and the bird nammed after a fruit (or is it the other way around? :confused: )

Down under indeed!.... New Zealand in fact..... Current Americas cup holders and people who play football in shorts and a t-shirt, no silk pants or nancy pads here thank you!!!

Anyhoo.... had wondered about bolting two mags together, now seeing it in the flesh as it were i might just be content with that for the high capacity thingy. We are only allowed to hold a maximum of 7 rounds in anything centrefire. Although my 10/22 is legal to have 10..... Shotties can have 8..... Although as far as I know there is no law against clipping 2 together. We seem to suffer from the same political ignorance as yourselves. Pistol grip and tatical stocks are illegal but thumbhole and drugonoff style stocks are fine..... Flash hiders are bad m'kay, but muzzle breaks are fine..... there is talk at the moment (election year) that EVERYTHING will be limited to 2 shots. Guns arent registered here only owners (licence), problem being that its the illegal users of firearms are commiting most of the offences but they cant take their licences off them, they dont have one ! So clamp down harder on those that we do know have weapons. See how that works.
Ill just step down from my soap box now and have another look at the posts on bedding and gas blocks etc
Cheers for the response eh, bound to have more questions on life and its relation to the Mini-14

5 round mags here are about NZ$80-90 (US $40-45 ish)
anything bigger is of course illegal but should you somehow come across some they are around NZ$150-200 for 20 round, $250-$300 for 30 round and about $400 for a 40, these would all be second hand and blue not nickle or stainless.

SO IT REALLY PI$$ES ME OFF TO SEE 30rnd NICKLE PLATED MAGS FOR US$10.95 !!!!!!!!


ps interested to here from any smugglers !!!!

Sorry, Im finished ranting and the meds are kicking in now. In answer to your questions The silencer is threaded onto the end. I think they add an insert into the end of the barrel and that is already threaded cos I retained the front sight (although its off now cos it looked silly !) .It drops right and down when warmed up and it gets friggn hot when I empty a 20rnd mag thru it...... not that I have one. Cant imagine how I shot with it before the silencer, It is VERY usable with it (noise wise, still working on the effect on accuracy) about as loud as an unsilenced 22 with normal rounds (not subsonic). Wanted to investigate sub sonic for the mini but everyone says it wont cycle with the reduced load and it will only be as quiet as the action anyway. The barrel isnt ported either.
I can see by phrases like barrel harmonics, cold shot and hunter that ive sill got some read'n and learn'n to do!

See here :

doonzl---You sound like you're making the best of a bad situation. I can't help but wonder about polititions who approve a silencer but outlaw a pistolgrip. Your groups sound about right. Here in the US we have to pay a $200 tax above & beyond the cost of the silencer which is outrageous. I don't know if you folks in NZ went though the samething with gun confication as the Aussies did but it really broke my heart to see all the firearms destroyed. At anyrate keep on supporting your brand of the NRA, the way things are going we will all need to be armed.

Keep the faith

doonnzl, After reading about your suppresser I can see the problem is not the alignment, but could be the weight of the suppresser. From your site:

.With a Suppressor fitted to my firearm, will it affect accuracy?
"No, but it may change the point of impact because of the added weight on the muzzle of the firearm. The slimmer the barrel profile, the more the point of impact will drop."

475 grams is over 1 lb hanging on the end of the thin flimsey mini barrel. As the barrel warms up the weight has a more pronounced dampening effect on the harmonics (barrel flip i.e. oscillations along the length of the barrel when firing). The only 2 options I see for you with a std barrel, is to take off the suppresser, or ask the manufacture if they would recommend you to cut your barrel i.e shorter is stiffer.
You asked about a smuggler? A mate from your country orders hi-caps from the states, seemingly with no problems, even a 100 rd drum mag!

Thanks for your replies brother shooters...... when I was ranting I forgot to mention that at any age here you can walk into any car sales and purchase a vehicle of any engine size and drive away without a licence. You can pull into a gas station and fill it up with as much fuel as you want and you dont need to produce a licence or even have the car registered or warranted (deemed safe for use). Drive as fast as you like and destroy as much property as you like without insurance. You will be arrested, and probably do time, but you will NOT be prevented from driving ever again just told you wont be able to get your licence for a bit longer. DAH didnt have one before why would I want one now? nobody checks when you buy a car or get fuel....
break any firearm law and you will lose your licence permanently, weapons will be confiscated along with your others that are at home (cos you dont have a licence anymore)and destroyed, I also believe you lose the vehicle you were driving as well (as is the case with illegal fishing, you lose the boat and car you were towing it with) if you were offending in a car. More people die by idiots in cars than by firearm, cos not all idiots can get a gun. But can you spot wich one creates the most revenue for the govt.?

Nurse !!! Pills stat.....

Bushwack - Is the TAX for operating a firearm or adding stuff to it?
Any firearm used in an offence here is confiscated and destroyed, not just if it was used in a robbery.... if it was stolen and recovered (evidence or sumfink), from what I can make out thru a friend of a friend. Not wanting to find out myself!

Cajungeo - I figured they ment the barrel wouldnt climb as much when shooting !! Not keen to ditch suppressor as I love using the rifle with it (dont need muffs) so I might investigate the suppressor that goes down to the gas block, it doesnt hang off the front as much. The extra length and the bipod does make it a little nose heavy.

Would be VERY keen to here from your mate, as anonamously as they want...... I assume you can get my email address.....

doonnzl, Sorry for the misunderstanding. I meant a countryman of yours, mentioned he orders mags from the U.S. over the internet, and never mentioned any problems legally, have you tried ordering over the internet? There are many sites that sell hi cap mags. Also you might want to consider cutting a couple of inches off the end of your barrel, to stiffen it up, and bring the center of gravity rearward, of course then you would have the expense of re-threading your barrel. It would be cheaper than buying a longer sound surpressor.

How do you reduce barrel length? Do you just hack it off or do you need to make it rounded ar the end like the original muzzle. I have unlimited access to a machine shop and would like to try this as I am not very happy with the accuracy of my mini. I am dealing with a decent group for the first five or so shots and then they steadily climb. A friend that I shoot with owns an older one and I can keep it at about a 2 in. group at 100yds consistantly.

Hey bugdrvr, I was mentioning the barrel cutting in doonnzl's case, because he has to have the 1 lb thingy on the end, and it causes his point of impact to drop, as barrel temp rises. In your case I would try a muzzle break similar to the black warrior at cheaper than dirt's site for $19.95. Everyone that has installed one has noted improvement. For most, it cut their groops in half! It weighs a few ounces, and helps stabilize the barrel whip.
Once you cut your barrel ya can't put it back. There are a couple of threads dealing with this. One is from a machinest with a lathe. The important thing is not to cut past legal length, and to recrown, the muzzle end for best accuracy. If you choose to do this, keep us posted. Good Luck!

Since you have access to machine shop, here is an article on crowning, you may find helpful:

After reading those threads it makes me wonder if the insert they put in the end of my rifle has a crown thingy at all. Will investigate this first then look at shortning.
My father has an engineering company that specialises in stainless so Ill get him to shorten if necessary. How critical is the radius/bevel in the end of the barrel? the thread mentions 1/4" radius?
Also wondered about getting a barrel shroud made up that will go between the gas block and suppressor, using the screwing down of the suppressor to put tension on the shroud and sort of brace the barrel.
Am not worried that customs will sieze anything coming in thats a bit naughty, Im more concerned about the associated fine !

thanks again for the info, its good to here from people with the experiences and knowledge to save me some major cockups!

doonnzl----They call it a Tax but in all probability the $200 is to cover some of the cost of proccessing your request. Your request for the Tax stamp goes to your county sheriff all the way up to the FBI. Each agency who gets it runs a background investigation on you & if you pass it's sent on. The process can take 6 months or so. The approved tax stamp is only good for the single item it was made out for. So if you were buying a silenced submachinegun you'd need a tax stamp for the silencer & one for the submachinegun. Most Americans have been led to believe silencers & automatic weapons are illeagle & can't be owned by them & this is not true. Usually if you're a law abiding person with roots in your community it's fairly easy. The thing is getting it past your county sheriff. Now if I were going to leagally silence a Mini I would start off with a heavy barrel conversion & go on from there. Personally I think the factory barrel is too light to hang a 1 pound "Can" off of.

Good shooting

Unfortunatley the problem isnt buying, its getting once it hits customs !! Am currently exploring an alternative but thanx for the offer.
Check out Percy engineerings web site:-

http://www.suppressor.co.nz/

They can ship to overseas.....in theory. Are they allowed in?;) Let me know if you hit a wall.....

Am currently working on a barrel shroud that will act like a brace between the suppressor and the gas block to stop the extra weight drooping the barrel. Will attach some pics when I get ahold of a camera, and range results when its finished.
