Hello,
sorry for my first post beeing a big technical problem question.
I am writing from germany( maximum restrictive weapons laws), an i managed to get a licence to purchase a semi auto rifle…
Being a M16 lover since my youth when i watched all those Vietnam war movies, i decided, against better knowledge, to buy a AR15 system.
Only importer for germany is Waffen Schumacher OHG wich is importing Sabre Defence XR 15 rifles for the german market.
Finally after more than 3 month of waiting, i got a mid length Xr 15 (M5) carbine.
After doing all the paperwork i went to the range enthusiastic to try out my new purchase:
After 3 rounds, i realised the weapon was unwilling to reload, so semi auto fire was impossible.
I tried out severall ammo brands( wolf 55gr., wolf 62. gr. s&B 55gr. federal etc.)
but none was able to reload the weapon semi auto and jammed every round due to short stroke.
So i sent in the rifle back to the importer.
They told me it was a problem as Sabre barrels where made for the military market, so the gas drilling in the barrel is 1.4 millimeters diameter(for military ammunition) and should be 1.8 milimeters for civil ammo…;-))??(sounds strange to me…)
however, i got back the rifle after severall weeks, and rushed enthusiastic to the shooting range again.
What a dissapointment.
The rifle now shots fine, but not with all ammunition:
Wolf 65. grain is just performing well, but wolf 55. is causing major problems:
i am just allowed to load 5 rounds per magazine. first and second round work find, on reloading the 3rd round, i always have a jam, as the new round stucks in a 45 degree ankle in the chamber…
as said, same wolf ammo in 65. gr. works fine, only 55. gr. makes the problem.
S&B 52.gr. ammo works ok, but i had 2 missfire round in 40 as the firing pin did not strike the primer enough to ignite it…
Also i had severall times the bolt catch failing to catch the bolt after the last round.
People might say:
discard the wolf ammo and use some better…
But as i am a believer in military weapon systems , it is like i cannot believe a military weapon system is addicted to special ammunition.
Shouldn`t an AR15 be able to fire any kind of ammo?
Especially as i found many reports in the net about Wolf 223 beeing used by AR15 owners without problems.
So, the importer’s gunsmith seems to be at the end of his knowledge,too…
any ideas where the problem might be?
I want to apologize for my first post beeing such a weird problem, but i am really desperate aboute it, as i really spent much money and time to get the licence for this rifle.
And there is no chance to return it and get another rifle for it, without doing all the paperwork and investigation again…
Germany sucks…
I am really looking forward to any help, and please apologize my bad english.
Thank you and all the best
Hans from Germany
Willkommen bei M4C. Viel Glueck mit deine Problem. Hat den Importeur das Gasloch aufgebohrt? Ich bin in der Meinung das problem war ein kombiniertes problem mit der Munition, der Feder und das Daempfer.
Hans, For starters, make sure the chamber is cleaned well and check the bolt and bolt carrier so that the carrier key is tight and the gas rings are there, all three of them. Do you have a chamber brush? Lube the carrier assembly as well. What buffer does it have in it? If it has an “H” (heavy) try a standard if available.
Now, check your magazines. One at a time, load an empty into the weapon with the bolt forward, work the charging handle to the rear and it should lock the bolt back. This is to check the magazine and the bolt lock.
Now, check for proper gas, load one round in the mag, chamber and after firing, it should lock the bolt back. If not, the ammo combination with the gas port needs tweaking. Do this for each magazine.
Wolf is know to be a little weak, if you can use and obtain maybe Privi Partisan (spelling) that may be better.
Hello,
thak you very much for your reply.
@ Iraqgunz: yes, he drilled the factory 1.4mm to a 1.8mm hole, as far as he told me.
I am not sure, never thought about the buffer beeing a problem. It is still the original one wich came with the rifle.
What would be a good substitute? @mark5pt56:
as a former infantryman i know how to keep my weapons clean, so i dont think that is the problem, although i always worked with HK weapons and i am quite new to the AR system. I use a chamber brush from the GI kit and oil up the bolt and carrier well. As mentioned before, i am not sure about the buffer. It's the standart one, i guess. I use a single piece mcfarland gas ring.first thing i installed after the original reloading problem. The magazines(PMAG) work well with other ammo. Problems are just with the .55 gr. Wolf. I will try to get some PRIVI, it's not as cheap as Wolf, but may be an alternative. Would a hydraulic buffer be a possible solution? Any ideas what could cause the misfiring/ with the S&B ammo? It's didnt feel like the hammer was hitting correctly, hard to discribe.
And the primer only had a small punch.
After reloading the round, it fired without problems?
CXould it be the bolt did not close completely in the chamber?
Would this be a short stroke indicator, too?
Thank you for help.

Wie Sie vielleicht wissen, es gibt verschiedene Daempfern (carbine, H, H2, H3, usw…) und manchmal muessen die aufgewechselt werden wegen die Munition. Ich wuerde andere Munition kaufen dass wirklich 5.56 ist und nicht .223. Wie Sie vielleicht wissen die sind nicht gleich. Das er das Gasloch aufgebohrt hat koennte problematisch sein.
Ich bin ja auch nicht sicher was 1.8mm bei uns sein wuerde. Das Gasloch ist auch ein Faktor weil nicht alle carbines und rifles sind gleich.
One of the bigger issues here is that the “importer” drilled the gas port larger. Now he is probably going to have to find the right combination of buffer and ammo.
FWIW- We use the McFarland rings on our guns and they work without issue.
Hello,
thank you again for your interest in my problem.
It is indeed new to me, that there exist different buffers.
Where can i find more information on them?
The M5 is a .223 weapon, i am not sure if 5.56 is the correct ammo.
The rifle is not made for military ammunition, as this would be a indicator for a war weapon, making it illegal to own in germany. So the barrel is marked as being .223.
I think the gunsmith did not make the gas hole bigger, just drilling a to small hole to the correct diameter. He said some weapons come with undersized holes from the factory( although i cannot imagine why?) As far as i can convert, he made the 0.06inch hole a 0.07inch one
In fact the weapon did never reload with any ammunition before he fixed this.
We tried severall brands(including winchester, Remington and Federal ammo), none of them made the weapon reload.
After he drilled the hole-to hopefully the correct size-, all ammo works fine. It really is just a problem with the wolf .55gr. and just every 3rd to 4th round.
I think it cannot be a big problem, perhaps the buffer is the solution.
I am really willing to try this out.
By the way: i found a similar problem in the list you sent me:

I have a problem that sounds like a “Short Stroke” but happens before the gun even goes bang.
When I load a magazine and pull the charging handle the bolt will stop half way with a round just heading into chamber. This happens with WWB Wolf and a few of the other less expensive ammunitions. Doesn’t seem to happen with M855 or XM/M193 but due to cost and some ranges not wanting 855 to be shot its become a real pain in the ass. I can pull the charging handle again and it will seat the round but every 2-3 rounds during firing it happens. Any suggestions?
Mags are a mix of Steel SA80’s and D&L’s with magpul followers rifle has under 2k out of it. I assembled the lower myself and am wondering if anything I did could be causing it. Upper is a MSTN build and when I run good ammo it functions. I would say its the ammo but when it happens during the loading cycle I wonder if I fucked up somewhere.
i wonder if the author managed to solve his problem. Could be a solution for mine, too.
Iraqgunz, where did you learn this excellent german?
And why do you have a german Leistungsabzeichen in the picture below your posts?
All the best
Hans
Leider kann ich dies nicht klar beantworten weil es so viele Variablen gibt. Das innere Durchmesser von .223 ist ja kleiner als 5.56MM und der Gasdruck is hoeher. Es ist ja moeglich dass, das Gasloch zu klein war. Zum beispiel bei einem M4 carbine das Gasloch is anders wie be einem M16A2. Es hatte mit der Lauflaenge zu tun unter anderem.
Ich wohnte ueber sieben Jahre im Deutschland (Hessen), die haelfte bei den U.S Armee. Die Abzeichen ist eigentlich einen Schuetzenschnur im Bronze (ohne die Schnur). Die habe ich bekommen von unsere Schwester Einheit waehrend training.
Gibt’s was bezeichnet auf das Gesicht von deinen Daempfer? Wenn nich dann ist es fuer einen Carbine. H, H2, H3 sind ja auch fuer einen Carbine aber meistens fuer Gebrauch mit kuerzere Laufen und voll automatisch.
