with the newest regs and reg materials.
Have you had any issues with the first shot after the rifle sits for a day or more?
Have you had any issues with the first shot after the rifle sits for a day or more?
A question for the owners of the newest versions of FX airguns
- Thread starter MP44
- Start date
Still have a problem it's not the regs it's a oring in the plenum . Try the search there are a couple fixes one is adding a peek disc and change the oring to different material

The o-ring in the plenum does not sit against a flat surface. It is thought that this allows the o-ring to flatten out and creep into spaces it should not be. This causes it to not release the valve rod cleanly when firing the gun. So one has a slightly lower FPS on the first shot or shots.
This is more of a problem with guns that have higher regulator pressures. Most of it can be overcome with a slight increase in hammer tension.
If that does not werq for you there are other things that can be done.

Thanks to your reply, I canceled my order for a Crown MK2 in .177. I placed the order yesterday as I thought after 4 years this issue would have been resolved. After sleeping on it I thought I better check with owners here on the forum.
FX never did figure out what was causing the issue with my rifle in the link below. The person I spoke to on the phone said that Ernest Rowe was also involved in trying to figure out the issue. After 4 months they ended up sending me a new rifle but I sold it un-fired so I would lose less money.

After the horrible first shot the rifle was super accurate. Also, FX customer service was one of the best I have ever had to deal with.

There are many other PCPs that do the same thing, if you crank the regs up, if not most of them.
It is a small thing. So, I don't worry about it is it can usually easily be overcome with proper tuning.
Otherwise just dry fire the first shot and you are good to go.
Actually, from what I have seen, the difference in velocity is not usually enough to worry about unless you are hunting and shooting long range.
Although if you have the dreaded OCD this can be a problem and the world is a difficult place to live.

The first shot high or low - is a big thing.
But personally doesn't bother me much, I shoot target only, from a bench, and a first couple shots are called "get on paper", for my own sake.

With a lot of my pest shooting, dry firing that first shot out of the case is not an option. Also, the first shot on both of my first generation Crowns was considerably off at fairly close range

The first shot or two...who cares about a few fps slow ? If it bothers you that much, just, always consider the first five shots...throwaways...simple.
Or, lower the regulator pressure a little as noted above.

It wasn't the FPS that bothered me, it was how far off the POI of that first shot was.
ETA: It cannot always be that simple to just turn the reg pressure down. In 4 months FX could not figure out why my rifle had the first shot issue.

Most, if not all, guns, including powderburners have the potential cold shot problem. Don't worry about it. Just shoot the first one in the dirt.

After reading your question I set up my lab radar and chronographed the first three shots out of my 6 month old M3,it has sat for 48 hours without being shot. The velocities were 937,937,937.

Normally the major issue appears when gun is set at low power hammer settings.
At high powers, the hammer hit overpowers the stickiness , extrusion effect of O ring.

I understand your issues with it. As a pester/hunter myself burning the first shot is not a fix. Target shooters sure no big deal but needing that first shot to be on is important when you shoot something other than paper. Your not alone there.

Yea, when I see a starling out in the yard, house sparrows or a squirrel on the feeder, or a skunk wandering around at 6 am, I always set up a test target before I take care of the pests.

from the quality of these reply’s its no wonder no one can agree on anything in this country and why things are so fed up

The difference of opinions here are mostly between target shooters, and pesters/hunters. When pasting, the first shot almost always counts. When punching paper, not so much. You’re always going to have difference of opinion,but as long as the OP gets the right info for his type of shooting at the end, then all is well.

I am sure you would know mubaur. I am new to tuning these Airguns and I enjoy watching your videos.

When you buy guns that you don't need to question it there's no point. And have had many a good luck with different brands like AAA Evol, Taipan Veterans, Kalibrgun Crickets, RTI Prophet, AGN Vulcan 3 and Uragan, Edgun R5M, RAW HM1000X, Daystate Regal, WAR WARP Cobra, and I'm sure there's quite a few more I've owned that had zero issues with this that I'm forgetting but point is made. Needing to check POI is not a necessary thing on guns. At least shouldn't be, they should just be there.
