MRodAir Air Max Varmint in .177

[WesBob]

I took the stock off my AMV today just for giggles.  It has the Artemis gauge, and it doesn't have to be removed to remove the stock.  Also, I thought I read the triggers were adjustable on these.  Anyone figure out how to adjust them?

Any other easy Mods for these?

Pretty sure the Varmint has the same set up as the cp1. Once the trigger guard is removed you can take the pins out and get at the trigger and sear. You can turn that little grub screw up so it is just proud of the top of the trigger where it engages the sear. Then find something to use as a sleeve over the pin that holds the trigger from going forward. This will get rid of the creep. Some use a rivet modded to work. Then take a spring out of a cigarette lighter and cut it to same length as the stock sear spring. Switch out the stock spring, makes lighter pull. You can use a valve stem spring as well. Makes a nice light two stage trigger! I'd also be careful about taking the trigger guard screw out with the tube pressurized as it is part of the valve retaining.

Wes I'll eventually be doing the rivet trick on mine, I'm not really concerned about the pull factor because the pull force of mine is no real big deal on mine, if I was going to be going to shooting matches with it I might but for hunting it's really been putting a smile on my face.  I will definitely be curing the creep on it though.

I just ordered a Varmint in 22 yesterday. Hope I don't get a leaker!

Mine is still going strong but eventually it will probably leak unless I replace the orings soon, I've got over 500 rounds through mine so far and haven't done anything to it except one time I did take the stock off just to have a look see.

You're right, the pull isn't that bad. The two stage trigger mod is well worth it though!

[WesBob]

I think it'd be good to mention again that there isn't a lot you should do on this gun while pressurized. If you take the breech off and the transfer port out, you lose all the retaining on the top of the valve. If you take the trigger guard off you lose one of the screws holding the bottom in place. There is another down there but pretty small and at 2900 psi it could blast it off pretty easy I think. Definitely wouldn't recommend taking the transfer port and trigger guard off at same time, almost guaranteeing an explosion, or at least a bang of the valve pushing the hammer back. Hopefully that would be all unless the back cap had been removed as well!

[WesBob]

I forgot, someone mentioned there is also a stop behind the valve too prevent the valve being removed out the back, so that is one more safety factor in place. Might be all right to remove the trigger guard with that there, though I would still be nervous about it on a full fill!

[Wayne52]

You're right Wes, it would be unsafe with any kind of significant pressure in the gun, when I did take my stock off for inspection it was down to a safe pressure and it wasn't a big concern for me because it was well under 1K pressure which I don't consider really too awful bad just removing the stock, next time she comes apart I'll be doing more than just inspection and I'll exhaust all pressure.

Sounds good, I agree shouldn't be a problem taking the stock off at that pressure as long as the breech was still attached.

That is real info that anyone who gets one of these should know...If  there is a spa bible/tech reference put together ever... that should be chapter one paragraph one...

I degas all PCP guns before I get into them. The few accidents that have been reported was enough for me. I don't think any of them would have happened without human error. I know my "lego" HPA guns are pinned with 3 screws that remain intact throughout the tear down... I still degas.

[tomiboy]

How does the rear sight come off?

[jarmstrong]

it is held on with the elevation adjustment screw. there is a spring that will fall out. then tap it off the dovetail

Ok so in your honor we will call it the Bill's famous chili warning...

and should read be titled "WHEN IN DOUBT DEGAS"... then the first paragraph describes exactly how the valve is heldi n place...

Thanks! I had the elevation screw out and pushed it a bit, but sounds like I have to give it a little more persuasion

[Wayne52]

I used wood to tap my rear sight off when I fitted a big scope on mine recently. I also filed a small portion of the dove tail down to enable room for the big scope.

There's still enough meat left on the barrel band/scope mount to remount the rear sight on mine in case I decided to sell it, but I doubt that's going to happen.

Yep, when in doubt.... pass the gas.

I just received a new Varmint PR900W in .22 from Modair a couple of days ago and I am very impressed with the quality of the SPA products. I have had some very bad expectances in purchasing Chinese machinery due to the LACK of any QC. This is my third SPA product and it will not be my last. I love the weight and feel of the Varmint. I had to buy one after reading all of the favorable comments from you guys and gals. Chickie's posting made me buy one, she was very convincing. Bob

chickie 's been very quiet of late, maybe she's on holiday

[avator]

I've talked to her some.... She's making her seasonal move from north to south and setting up her new "playhouse".
