    Air Venturi Has anyone put new prints in an air venture avenge-X?

    I've posted previously about the o-rings in the Avenge-X I was quite frustrated with mine at first and had leaks at several locations Some of the factory o-rings were almost square and hard enough they shattered when removed. After braving a complete tear down and replacing all the o-rings, I...

    Antifreeze in your pcp compressor?

    This site is a great resource for choosing a compressor - I've got several and stories to go with most of them - price isn't a good indicator - I purchased a set of five compressors that didn't work from a manufacturer - got all five for $150 and a half hour drive - playing with broken toys...

    Air Venturi Avenge-X reg creep

    I have thousands of rounds through my 25 cal Avenge-X at this point - had very frustrating start - didn't hold pressure well, didn't regulate well and of course, then it didn't shoot consistently - At times it would leak to about 100 bar overnight. The regulator was one of the big hurdles - and...

    Antifreeze in your pcp compressor?

    I have two compressors that use a closed circulating system with a radiator - although my comment could apply to an open system using a bucket and pump too. I'm running a pre-mixed "ready to use" antifreeze designed for aluminum parts - not worried about freezing but don't want any corrosion -...

    Air Venturi Avenge-X reg creep

    The o-rings in the regulator of the Avenge-X seem to take a beating - I switched to only using pure silicone oil rather than silicone grease - that helped a little - but I have replaced the o-ring inside several times. Replacing the tiny o-ring on the end with a slightly tougher material made...

    Air Venturi Avenge- x classic

    I bought the Donny FL Yokozuna in .30 cal at their recommendation - expensive and a bit heavy but has been very quiet even pushing 70 FP rounds out of the Avenge-X .25 cal - they recommended that you go up one caliber if the barrel is already moderated and the unit won't mount directly to the...

    Air Venturi Avenge-X O-Rings

    I had some early leaks and then an odd failure - at about 3500-3800 lbs while filling, the burst disk on the gun blew out - this seemed to create a cascade of failures - couldn’t even begin to build pressure with my little compressor and it clearly wasn’t a single point - that prompted the first...

    Air Venturi Avenge-X O-Rings

    You need a caliper to measure the o-rings or compare the old one with the new ones - In my gun there were a number of o-rings that were so deformed or stiff that they broke when trying to remove them - that makes using a caliper really helpful - even if its a cheap plastic one, you can measure...

    Air Venturi Avenge-X O-Rings

    that IS the problem - they are all black in the package but two different shore hardness values.... the harder shore 90 rings are all in the high pressure side of the gun

    Contact areas in barrel?

    My gun now falls into the "one-off" category - so not completely repeatable. When it was stock, I was maxing out around 870 as well with 33-34 gr pellets and slugs were slower than pellets for the same weight. Increasing the shot pressure above 175 bar wasn't all that helpful (or consistent)...

    Air Venturi Need Avenge x info

    Two different steps here - removing the barrel is super simple - there are two recessed set screws in the scope rail on top - loosen these two screws and the barrel is free to come out BUT - there is also a pin in the end to index the barrel - so it always goes back on in the same relationship...

    Air venturi avenge x .25

    My Avenge-X has been quite consistent - routinely put 8 rounds in a dime sized group at 50M My shooting skills are rookie+ but haven't had consistency problems with the gun. Shoots pellets and slugs quite well.

    Air Venturi Avenge- x classic

    It was may "onramp" and the 25 cal has been a lot of fun. Works out of the box and with a little tuning shoots better than I expected - leave money for a decent scope - the Donny FL 30 cal Yokozuna moderator eliminates a lot of the noise but its not super loud to begin with (they recommend the...

    SCF60 Compressor by DMC?

    Anyone have this compressor? I just purchased five "broken" units at a price worth taking the chance. The water cooling circuit uses a clear plastic piece in the water jacket around the one cylinder - all five units this ring appeared to have stress fractured - either from heat or the coolant...
