We are not supposed to discuss internals on here so I won't, but anything you can think of is usually, but not always, better than nothing. The times we live in.

Other Truth behind Macavity Arms Prototype Airgun
- Thread starter Airgun Advisor
- Start date
For the ones of you who have done adjustments on the prototypes or Genesis rifles: if I decide to adjust my regulator, clockwise or counterclockwise to reduce the shot pressure?
I am waiting for a chronograph I ordered to set some base numbers. But seems sometimes adjustments are counter intuitive to results expected in many of the posts I read.
Maybe my steadiness and vision are causing the random spreads sometimes. But a lot of my shots seem to be tumbling from the long tears in the paper. 3 shot groups at 25 yards, 1.33" target width

day was going pretty good. out early, shooting fairly decent groups and then my side lever basically just fell out. found bolt that holds it in on the ground. Had to remove scope line it back up and reinstall retaining bolt. wasn't quite ready to start having to take apart the gun quite yet. luckily it was something simple and easy to fix.

none. lever is smooth and easy all the time. no pressure or friction from the bolt, it is just a pivot point. I had picked the rifle up from across a table I was filling it on and I probably held it upside down a few seconds and apparently the bolt just fell out. Had to remove the scope to get it back in correctly it goes through the picatinny rail. put everything back together and it is shooting great again.

I want to get to know the gun a little better before I start locking things down. Still haven't worked up the courage to start taking it apart or trying to turn screws to change settings. I have a chronograph on order that should be here early next week. that will give me a true idea of what is going on with the rifle. I am pretty sure there is a setting off somewhere. I always thought a regulated PCP would shoot pretty consistent through many shots. I am getting 24-30 and then the shot groups start dropping to the lower right. Macavity says it should get almost 60, although short barrel is rated at 30. That is why I am thinking the internal regulator might be set at the higher setting for the short barrel. I am new to Airguns and PCPs especially so not sure what the curve on shots and behaviour should be.

Sadly, this is not uncommon, but also not a big deal. Most of us have a least one screw loose …WHOOPS!!!! ill definitelly b waiting a year or 2 to get the bugs out!

Pretty sure I have several loose screws. Thankfully that is the only one I have found in the rifle. Also, I need to stop just looking for something else to buy because of the rifle. Milligram scale, micrometer, chronograph, etc... Just to get groups better and try to convince me it's not just me!

I just picked up HT-X3006 I read several different threads where most said it was fairly accurate though maybe not exact. Worse comments were that it was a bad way to attach to the barrel.
I just tested 10 shots and they ranged from 795fps to 800fps. factory says the .25 MA2 is set to 890fps. I haven't changed any setting and am using their recommended pellet. any suggestions as to whether I should do an adjustment to one of the settings to see if I can get it to 890fps? I do not know anyone around my area with a Chrono that I could match it to.

I doubt that your chrono would be off more than 15fps, mine have all been within 3fps of each other. Another way to check your velocity is by using Strelok and checking the drop between distances. If you input all the data correctly for the app this should be very close.
Let's just assume your chronograph is accurate and you you are shooting 800fps, by all means turn it up. Loosen the set screw on the side of the hammerspring adjuster and crank it in a full turn and check the speed again and again until you see the number near where you want. When you get near your goal you will need to go down to 1/4 turns. Don't forget to retighten the set screw after, and don't reef on it, just snug. You don't seem to be trying for crazy numbers, or use heavy ammo, so adjusting your hammerspring is most likely all you will have to do. Good luck!

after removing cover, found set screw very loose. went ahead and adjusted hammer spring while testing. tightened set screw, 9 shots after tightening. seemed pretty stable. I'll have some time over next few days to see if it improves groups and holds setting

Gstrain, I found that the set screw does like to come loose but don't overtighten it, just use blue loctite if you need to.

Seems like a lot of posts I have seen say the hammer spring setting really doesn't need a set screw but I'm thinking it probably does. At least now I've taken the gun semi apart and it does not make me nervous to access the internal settings. Still seems like I am not getting the shot counts that Macavity is publishing. But have not had the time to put a couple of hundred rounds down range to see if setting the hammer spring setting is going to change this.
Thanks again for your help. Being new is tough with a totally different technology than I have played with before.

With the Hammer flying forward and hitting a valve, a set screw seems reasonable to me. My AAA Paradigm has one too, I like the added measure.

Those proto type reviews with the flaws don't help production marketing . In fact, I think they scare off potential buyers. I have a .25 cal Avenge XX Tact with Riton scope and she is dead on at 50 yds! I zero at 30 yrds. I was able to snipe an obese squirrel at 67 yds! (used golf range finder) I was hoping this Macavity was going to add competition in the Avenge X and Cuda max realm but not at this time. It thought it was a bad idea to do a video with a proto type.(too many flaws and as mentioned the gun may have noticable improvements. The review should wait until then.Im not buying the hype. supposed to be 1 moa and looks like a shotgun pattern??? my air cuda standard shoots half in. groups at 50 yds. all ive done is adjust trigger with new trigger screws. ill be waiting few years to see if they work out there bugs and issues. also comes with moderator super loud with out[110 decibels],,,,and does'nt shoot well with mod???

Disagree. People are always looking for something, true, but the purpose of a released prototype is to get feedback and make it better. Besides, there are not any "FLAWS" as far as I can tell. I don't know about the thimble but it's not a problem on my gun either. The people getting shotgun groups are simply not tuning their guns. Just trying different pellets out of the box might work sometimes but sometimes you have to change the regulator pressure and speed too, the whole node thing. Then there is finding the right ammo at the right speed/pressure. It's a process, have you ever watched an AEAC review and see what he goes through? That's what we all go through. People complained to Umarex about the Gauntlet not being a sidelever gun and they fixed it. I am glad for the opportunity to complain about the breech o-ring not being on the probe; hopefully Macavity will move it to the probe. I got mine to finally do moa at the 50y I shoot at, if people are afraid of buying something because they have to actually go through the process of figuring out what works than they're going to have a tough time liking airgunning at all. The plastic magazines supplied with the prototypes are hopefully not the ones that will ship with final production guns, they have metal magazines already. If they continue with the plastic ones, that would be disappointing, but not actually a flaw of the gun, just a bad business decision. Your Avenge X tactical is not a first generation airgun from a new company either, so comparing against that gun is a stretch. I can tell you that having spent time with an Avenger (very accurate) that you would be very impressed with the build of the Macavity. People who scare and run off easily from a simple, incomplete, quick review, and can't take them in context, need to educate themselves more about airgunning as a whole than any one airgun in particular.

And Joshua777, the Aircuda didn't show up perfect either. It was delayed for quite a while with a really loud ping as I recall. They were just more selective with who got the prototypes and didn't just sell off the first production run to the public.
