Ak barrel extension Causing short strokes?

[CSACANNONEER]

Chunky,

You're not imagining things. I too, had a barrel extention (fake can from AK builder) that worked fine with most of my builds but, short stroked on one of them every time. I ended up selling the fake can to someone who really needed it to make length on his bullpup build. I never figured out what the problem was, I just know that it can and does happen.

I dont know what the problem is here
maybe some of you dont understand
forget the extension for a second
do you understand this rifle has worked for years as it is now
no problems

Now if I add a extension it doesnt work PERIOD

What more can I say, I have no need to take anything apart
no need to start buying more parts wasting time and money
its not like I can just test shoot this thing whenever
it takes time and money to go out and shoot it
I was lucky to have today off

im not going to invest any time to solve a problem when all I can do is not use the tip and problem solved

obviously the tip is causing problems im guessing with pressure
instead of fighting me about it, and the lack of work im willing to do all I want to know is if you will take it back since you have offered

Im not going to spend my time as the problem solver for this product its just not worth it

Obviously parallax wants nothing to do with this as they can answer my first e mail the same day I had problems on a sunday, but now its tuesday night and they never answered back.


I already sent you a pm today about this but you have not sent one back either
Its not really a mystery, it just doesnt work

Bud, it'll only take you 2 mins to take out your fcg and check it out, either way good luck.

Thanks for the post
Im not trying to say this product is bad
Looks to be really quality made
But its either that brake or those small holes causing pressure issues
either too much or not enough
and if its the first not to work from all the ones sold then thats great
But its not working on mine and I have video proof im not making anything up

[CSACANNONEER]

I don't think it's the product either. I know my guns all worked with the extention I had except for one of them. That one ran and still rins fine without it though. I sure don't see a need to pull your FCG out since, your gun works fine without the tube on it too.

Yes exactly
because if I ever take that tip off since it is removable and not perm attached then who knows how it will run in the future
I see no need to make any permanent changes to something as precise as the trigger

believe it or not that trigger really feels nice compared to my other ak's very smooth

what if I had an out of battery explosion because of this problem or worse some sort of auto fire
that hammer resting on the bolt as its cambering a new round has me worried about that and my safety

[Mamluke]

I saw the video, its really oddball that the new chambered round wasn't fired, since the hammer did not lock back, and followed the forward motion of the bolt carrier (as in full auto) yet failed somehow to strike the firing pin!!! That's whats bugging the heck out of me lol ...

BTW, I don't think that qualifies for short stroking, since a short stroke does not involve chambering a new round into battery!








... I could be wrong though ...

yeah im no expert on gun terms
it was the one that sounded correct on sunday when I really wasnt sure what had happened

what would it be called then?

hey I have no problem taking it apart, I built it myself

the problem is its at my dads so its a 45 min trip each way
then either do it there, take pics or a video
get those online
then sit around and wait for someone or someone's to say it needs this, or that
then possibly ordering parts or everyone scratching there head because the spring looks to be good
maybe wait a week for the parts
then who knows when I could shoot it
drive 1 hr each way to shoot it, to find it may do the same thing again or worse another problem arises

Now I could be 2 weeks in or longer, where if I can return it after a couple days in mint condition its better for everyone that way

We have to INVENT a new term for your situation pal .... attention all terminology & tech specialists, chime in as you please ...

........ FTF?!

FTBOH
Failure to blow off hand

[Mamluke]

I think a weapon's expert or a gun smith, after the 'FTF' incident, would take the dust cover off and the recoil spring, and then manually pull the hammer back to see if it will catch. Then put everything back & pull the trigger to see if it will fire and chamber another round.

I DON'T ADVISE YOU TO DO THIS YOURSELF, its very RISKY since you have a live round in battery!

The protrusion on the back of the bolt carrier is intended to keep the hammer from striking the firing pin unless the bolt is locked. which is not to say that hammer follow can't cause unintended ignition because it certainly can(guess how I know). I'd be willing to bet the primers on the rounds that failed to reset have a visible light strike.

Chunky, something in your FCG isn't working properly. The new muzzle brake is just causing it to show itself. If you don't want to deal with it you don't have to. Just be aware that it "might" happen later on without the brake. When you built your rifle did you function check the trigger group. I'm not trying to be insulting lots of people just flat out forget or don't know.

I showed on the video but you cant see no marks on the primer
I was worried about that too

I also have hundred of rounds through this, not that its alot but this is not some new rifle or a recently built one
its been used alot when I first built it and havenet used it in a long time. Just recently started to use it again

Im not worried at all about future problems with the trigger
I thoroughly tested it when I first built it with the trigger seeing how the action worked, tested it in the field
all seems good
still even have a dozen cases of the very first shots with it so I could compare the primer strike to other rifles
I was very thorough in assembling it

...carry on.
