Barrel bushing ?

[Little Rhody]

I have a Wise Lite Barrel Bushing repair part. It seems to screw into the Flash hider about half the distance easily, then it begins to get tight. I can turn it in another 1/4 of the way If I force it, but I can't seem to turn it in all the way. There is'nt a taper on the threads of the flash hider, the threads on both parts appear to be in perfect condition with no damage. Does anyone else have this problem? Should the F/H need to be screwed on with a spanner whench? if so I don't see a need for the the lock at the end of the barrel shroud. I would think you should be able to screw on the F/H by hand.
See pics:

Whoops...pics are in reverse order.

I ordered 3 of these bushings and all three were the same as yours. On a combined 8 different boosters. Seems WisLite didn't cut their threads deep enough. Bummer. Shipping back and another long wait unless you have tooling large enough for this. Thats a pretty big die. Good luck.

Is this a known problem admited by Wise Lite, or is this your observation and guess to the problem? If this is a know problem by WLA, they should have a recall on the parts.

As for having a die that big, I believe the parts are built on a cnc lathe and don't use a die to cut the threads.

I am not trying to start something with this reply....
....but did the manufacture set these up for "metric-threads". They may be close.....but if not metric, they will bind-up.

If the manufacturer won't take them back and correct the thread-problem.....you can always go buy a "thread-file" and "hand-fit" the part to your Flash-Hider-Threads.

This is pretty well known across these forums. Many if not a majority of folks cannot get their boosters screwed on. The threads are not cut to the same spec as the German ones were. I have 8 boosters and none would turn onto either of the three bushings from WLA. The possiblility of this just beeing a random coincidence would have to the something like 1:1,000,000. I'm waiting like the rest of us for WLA to offer to recut these. Until then they are just paperweights.
What are folks doing for rear receiver sections on thier M53 builds? Good luck with your build.

i received mine and it screwd on fine-i read that some others were having problems-and if i remember right they would screw it on and off time and time again-until the booster "cleaned" the threads on the bearing.

waffendude is right -- at least in my case. I just took my time and worked it on and off WITHOUT FORCING IT and now it screws on smoothly like my other one. Some guys said they used a lapping compound to speed the job. You might try that.

Get a thread restoring file at a tools supply store. They usually come with 4 side and each end has a different thread pitch, 8 different thread pitches total. Mc Master-Carr has a metric one for about $8.63 P/N 8309A11. (page2252 of catalog 111). They also have one for internal and externial threads. P/N 2542A42 for $21.34. They are kind of like a stock checkering tool. They have parallel teeth the same pitch as the thread needing to be cleaned up.

Try them, I have and you can deepen a shallow thread that is to tight and get it to screw in.

I am well aware of the diferant types of thread chasers, taps, dies. My threads are fine, infact they look perfect. Clean, straight, no burs. Infact when the parts are screwed together, and I look in through the small vent holes on the F/H, I cant see any more threads showing. Threfore this tells me all the threads are engaged, the clearance must be too tight.

As I was reading all of the responding posts to this thread, I was thinking that maybe dimond dust lapping compound would work to final fit this. This mybe my final choice to fix the problem. I guess I just expected more from my $125 investment.

Before modding the part, ask Wiselite to fix it.

If they care about their rep (and with all the dealings with us of late, they should) they will fix the issue.

I bought some of the barrel bushings from wiselite(Weaponeers group buy). Some the boosters went right on ,some had to be lapped with valve lapping compound.

Another thing you might try is burnishing the threads with a wire wheel on a bench grinder.

Hey Rhody Mine Screws right on come By and check your Booster Bearing Peice with my F/H and Vise a Verse. this may help you out maybe its a German Yugo thig its possible there is a Slight difference.

Who has barrel bushings for sale at this time?

[rocco1911]

Wise Lite Arms has them for $125.00 each. but apparently Little Rhody and some others are having trouble screwing them down on the Flash hider. mines fine though.

I have tried mine on 3 differant boosters-no problems. But it is starting to seem like it is the luck of the draw.I would like a post from Wise-lite addressing this.I would hate to see them get a bad rep over something like this. ---bil

I just now ran across this thread.

My apoligies to anyone who is experiencing problems with this WLA product.

OK, one thing you all can do to assist me with isolating this problem.
Take a look at the "recoil boosters" that you are trying to fit onto our "barrel bushings". If they have not been too heavily worn or re-finished you may be able to discern markings on them.
We suspect that there is a mix of Yugoslavian made and German made "Recoil Boosters" included with the M53 sets that are being sold.
It would help to know if it is one make or the other that is such a tight fit.

If you can tell what the markings are then please post which ones did or did not fit easily onto our barrel boosters.

Please allow us a few days to analyze this and figure the best solution. I will post more here soon.

Hi Wiselight:

I've got two of your bushings. Of three flashiders I have, all spun right on one bushing, and two spun on the other. The third went on part way, and then tightened up. A few minutes with valve grinding compound cleaned up the threads...on whichever part was tight, and all the combinations are just fine now. I'll have to look at my flashiders, and see if they are all Yugo, or German, or a combination. The tight flashider went on pretty tight on an MG3 bushing that I have too, so I'm betting on "out of tolerance" flashider threads.

Here's a photo of one of the bushings in the front of a Yugo shroud.

Thanks for sharing that info.
Now I wonder if heat from firing has some long term effect on the "recoil boosters"?

Great looking job fitting that "barrel bushing" into your Yugo barrel shroud. Thanks for taking the time to post that image.

We will get our heads together back in the shop and look at the information that gets posted and check samples we have on hand. Of course I won't be able to get everyone involved until Monday.

I'll say "thanks in advance" to all who lend their information to this thread.

[schaubel777]

Wiselite,
Good morning. I'll take some pictures within the hour of my dfferent combo's and list the markings on the flashiders. 3 are German and the other 5 are Yugo. All three bushings don't fit any of the flashhiders. I'll take some pics though and see if I can figure out how to post on this sight. BTW, excellent prodects!!
