Stoeger X20 Suppressor fatal flaw
« on: March 08, 2012, 01:31:45 AM »
I was looking at my coke can with over 100 pellets through the same 1.25" hole spread horizontally (most from 30 yards) and thought well, spread's horizontal- why?  Pretty darn accurate gun, but must be the plastic washers making my spread horizontal, right?  WRONG!  It's NO WASHERS!  I was pretty peeved by this.  There is a raised area that is smooth on the sides of the barrel near the breech where the washers would normally go.  I just happened to have a couple of brass washers from Gene's tunes and toys laying around, and they match up perfectly with the raised area.  So, what to do?  I just very, very carefully cut the plastic out along the edges of the raised area with my razor-sharp Buck lockblade!  Gotta use the right tool for the job!  .  Beneath that plastic shroud is all metal, and the plastic i removed was just a hair thinner than the thickness of those brass washers.  They popped right in- a perfect, snug fit.  And the barrel fit just perfectly snug back into the compression tube.  Now my lockup is noticeably more solid.  Re-zeroed at 7.5 yards in my garage and then stacked 5 Kodiaks in a hole about the same diameter as a pellet off-hand, no problem.  Sorry no pics, it's passed midnight and I gotta work in the morning.  I just couldn't stand looking at that can, knowing that I have laying around something that might cut my 30 yard groups in half, and not doing anything about it.  Btw I broke down- the GRT-III is coming in the mail!  This is the 3rd GRT-III trigger I've purchased- worth every penny! I put one on every airgun I buy that fits it!

Lambchops- The X20 has a solid steel barrel and breech block.  The Suppressor model's barrel and breech block is also steel, but with the exception of the breech block face it is completely shrouded in plastic.  In the breech block of the regular X20, there are plastic washers on each side of the bolt hole.  In the Suppressor model, instead of inlets with washers, there is a raised circular area molded into the plastic around the bolt hole to fit the end of the compression tube.  In order to install good brass washers, you have to cut the plastic out to fit them.  By installing brass washers, you get a noticeably tighter and more consistent lockup which improves accuracy.  You could also probably just shim it, but i PROMISE you that the plastic beneath the shims still flexes.  You might not notice it, but it's happening. Without brass washers, you X20 will never be as accurate as it could be.

Mine was fine, too- but now it's better.  This X20 is my baby, my #1 airgun- so I'm gonna milk every last drop of performance out of her that i can get!

I thought I had your No 1 gun (Grin).  Oh I guess it is your OLD NO 1 Gun.   Good work on the X20S.

You got that right.

Thanks for the information, attached is one of Gene's X20s teardown photos (thanks Gene), where I think I highlighted the raised plastic areas mentioned.  When I did my tune, I thought those were plastic washers and just really hard to remove or glued/staked in some how.   Thats another part to look at for her next tear down.  :o

Bryan,

Is there a metal recess or lip that will hold the bronze washer after you have cutout the "plastic washer"? Or is it critical to carefully cutout the "plastic washer" and the new hole becomes the only lateral support and locator for the new metal bushing/washer?

Thanks in advance for your insights and help.

No lip that I noticed, but there is a steel sleeve of sorts that slides inside the bolt hole, slightly larger in length than the width of the metal breech block but not large enough to fit the brass washers tightly.  It will keep the washers from covering the bolt holes when you are putting the barrel back on, which is all you really need to worry about.  If you fudge cutting the holes a little, it probably won't matter.  I cut mine perfect to fit though.  That way the brass washers "popped" in, nice and tight =D

   ::) you think by now company's  would  use  brass washers. I guess  its always going to be that way , some one trying to skip on quality even when it counts the most, or do they think the brass washers  would wear just as fast  hhhmmm

They may wear the same, who knows?  The real issue here isn't wear.  It's the way that plastic can mash and flex, and in that way, effect accuracy

I noticed the same thing when I tore mine down earlier...... A 3/4 Forster bit later and instant brass washer placement!

  8)  Yes That makes  sense  less flexing, and with proper lube on pivot  joints  maybe  the wear  would be very minimal thru long period of  time
