    Best material for modifying the FX hollow moderator.

    I did this to one and it seemed to quiet things down a bit. At least it changed the tone so it seemed quieter anyway. I also picked up some of the cone baffles somewhere which seemed to do a little more. https://www.ebay.com/itm/303946465366 https://www.ebay.com/itm/115390515018

    Is there anyway to rehab a smooth twist barrel?

    Push a pellet down the barrel with a wooden dowel or cleaning rod and feel for tight and loose spots. If it is just a bit loose you may be able to polish/lap it, to make it more even, all the way down to the rifling. This may make it shoot better although your preferred pellet will likely...

    Compressor?

    I filled my 88 cf bottle with my Yong Heng when I first got it. Gave it a rest every fifteen minutes and it did the job just fine. As mentioned in the post I linked you to with a fan blowing through them and a bit of ice in the reservoir it will likely fill it in one sitting. although I would...

    Compressor blowing burst discs

    Like others have said it is usually a restriction somewhere down stream of the burst disc. I had the same problem, but less often, with my Yong Heng and eventually found my filter cartridge was causing the problem. Once I replaced it I no longer had a burst disc problem.

    Compressor?

    There are plenty of compressors out there. About the best you are going to get for under $1500 is the Yong Heng and its only $300 so a very good deal. Yong Heng post link https://www.airgunnation.com/topic/a-dedicated-yong-heng-subforum/#post-1127767

    Tap water vs distilled vs coolant for compressor?

    As stated earlier, in the discussion, distilled water will eventually remove material from your aluminum parts. Plain water cools better than coolant although I have used a 20% solution of coolant to 80% water without any temperature rise noticed. Plain tap water with Water Wetter is what I ran...

    Thinking about an LCS SK-19, but have questions...

    Love my SK19 even with the bad barrel it shoots 3/4 inch groups at 50 yards. AEAC managed to tune one to do half that at the same range. The trigger is a bit strange but I shoot well with it anyway and after awhile you get used to it. Full Auto is a blast and you just have to do it now and...

    Zero Recoil Zero Play Scope Mount - Sorry Dianna...

    Thousands of rounds with my 54 with the Diana mount and it has stayed accurate under 3/4 inch at 50 yards and near 1.5 at 100. From what I gather though they did have a run of bad mounts or copies get out many months back.

    Zero Recoil Zero Play Scope Mount - Sorry Dianna...

    Don't have one of the Gamo guns but do have a Diana 45 and 54 which are notorious for punishing the scopes. I trashed at least six scopes with these guns but none since I put the Bullseye mount on them. I have not had the flyer problem some have ether. Then again I took the time to clean...

    Duct seal pellet trap vs rubber mulch?

    Both the rubber mulch and duct seal traps werq very well. I prefer the Duct seal for indoors as the rubber mulch smells like rubber. Never had a pellet go through any of my 5lb bricks of Duct seal even at over 100fpe. Still my oak box did split after many years of use so now I just stack the...

    Crosman 2300T c02 leaking from barrel

    That would be the valve leaking past the stem seal. sometimes a drop of oil on the tip of the cart will take care of the problem. The stems are cheap from Crosman, you can call them and order one, and they can be had many other places as well...

    Tuning Finished up on my Impact barrel tension mod.

    Only the barrel housing is put under tension and not allot of it. The main reason I did this mod is to stop any poi shifts that are caused by the barrel being bumped and moving slightly. Even though I did not have the problem others did.

    Tuning Finished up on my Impact barrel tension mod.

    Only the shroud is compressed the barrel housing is under tension as the shroud is compressed. This does little to help the liner which is why I installed the carbon tube on the liner as well.

    Tuning Finished up on my Impact barrel tension mod.

    I just pushed down on it while it was sitting on the bench. Before the mod it moved a considerable amount after it did not move at all.
