Barrel length should be the length of the solid portion of the tube the pellets travel through. It doesn't have to be rifled and the pellets or bb's don't even need to be in contact with it, but it should be one continuous piece of metal. There have been guns made in the past with barrels that open up halfway down the bore so that the total length is very long but the pellets only contact the bore in the first few inches. I believe the intention was to provide a long sight radius while keeping the lock time/barrel time as short as possible. It was also quite common with defensive rifles in order to meet the 16" minimum barrel length requirement. They'd make the last 4" or so of the barrel some sort of permanently attached flash suppressor.

About the AR15 yes that is true as long as it was permanently attached it counted as barrel length. On a Guantlet the rifled barrel is covered by a shroud these are 2 separate things you can't say the Guantlet has a 281/4" barrel. It is 231/2" the shroud is 28.

Hi... It's Marker...I keep looking at your RPA...Question...is that a Pistol Scope..or is a rifle scope with a 3" eye relief...and is that scope only being held on just by the rear mount only and is the front mount there just for show ...just Curious

Yes it is a rifle scope. I only put it on to mockup and see if a pp750 rear scope dove tail would work. I end up using a fixed 4X scope with parallax adjustment down to 5 yards, it has 7-9'' eye relief, so a Taco hold is required.

I’ll have to reach out to Clayton, I’ve gone and checked out his store but it was closed. I believe it’s because he was at airgun Oregon for the comp last year.

Hey hey, whats going on? Im down for a shoot sometime.

If that one is that bad I can grantee the piston seal is just as bad if not worse.

There are videos on rebuilding them. Not that bad if you are mechanical. Just lots of little clips and specific order of assembly. I have done both of mine in the kitchen table with success.

So, fishgod - did you get your Zelos .22? If so, how's it shooting for you?

Click to expand...

Sorry for taking a while to get a proper update. I wanted to get any issues sorted before posting

I'm in Canada so I bought the Zelos .22 through Wes at Airgun Archery Fun, as well as a bottle adapter. Stand up guy, no problems there. The gun itself was flawless, however the bottle adapter was leaking at 2 out of 3 orings. The adapter to bottle connection oring was too small and unable to make a seal. (2.4mm thickness instead of the 3.1mm which I replaced it with). Also the fill valve oring had a large gash in it so I replaced it with a new identical one. Managed to get both at a local hydraulic store who didn't even bother to charge me for them since they were such small items.

After a thorough barrel cleaning, the gun is shooting excellent. As I want a fairly high shot count, I turned the pressure down to about 1600psi which had the JSB 18.13 (the most accurate pellet out of the ones I tried) shooting extremely accurately at 895-900fps.

Tuning it was a bit trickier as it seems the stock hammer spring was too stiff to have any usable adjustment at this lower pressure. Increasing spring turns was not giving any adjustment, in fact, it was slightly decreasing fps as the spring increased. I read about this on a different thread about the zelos and copied the shorter replacement spring suggested. This gave me adjustability from 500fps to well past the peak curve. I managed to tune it properly and the consistency of the fps increased, as well as the efficiency.

Shot count is excellent for me. After tuning, I get around 80 shots at full pressure, and the 700cc bottle I swap to afterwards gives me at least 200 more shots. So I am able to have close to 300 shots total at 900fps.

Accuracy is also excellent in my opinion. At 30 yards, a grouping of 5 shots makes one larger hole, about twice the size as the diameter of the pellets. I'd be pretty confident in being able to hit a literal pea or corn kernel 9/10 times at that distance. At 50 yards, they are less than 1/2 inch center to center. At 75 yards I get about 1 inch center to center. Anything beyond that distance and the wind played too much of a factor to give a fair rating.

Final thoughts: I'm extremely pleased with the gun once I got everything sorted out. The shot count is much better than I had hoped, so I may play around with increasing the pressure a little bit more. Accuracy has been great even in a light breeze, although I haven't had a dead calm day to try 100+ yard shots for fun. The trigger after adjustment is also very nice and light with in my opinion, a short and crisp second stage.

Happy to discuss anything else about it more, thanks again everyone for all the input!

Spectacular groups with the swaged slugs!

ARW said:

Thanks.....Yeah, I just ordered it this evening and am super pumped about this setup and can't wait to get it and start shooting it. I kept hearing for a while about BRK coming out with a slug barrel for the Ghost and they finally did. If it shoots anything like my current Ghost, I will be very happy. This barrel is 28 inches long compared to the original 23 inch also.

That's a perfect length barrel for easy added power! I am sure that barrel will sling slugs with great accuracy! I hope you post some pics of shots and thoughts when you get it . Again, congrats!

All my HT-X3006 adapters are already out there: https://www.thingiverse.com/thing:6977381
I think I can just create a single dovetail adapter that fits the Nate, which would allow reusing the mounts I designed for the HT-X3006.
I want to be able to use the sights on the pistol when firing. What is the distance between the sensor bore-line and the top of the Nate Chrony? If it's more than ~ 1.5 cm, how big is the sensor area? On the HT-X3006, I can offset the pellet path a few mm to get the sights above the housing.

Click to expand...

The distance from center to top is ~15mm & bottom is roughly the same, however alignment is absolutely critical (new software has alignment detection though - so you can detect if there's an issue)
I would not recommend to use the outer surfaces on the Chrony as a reference point, and only recommend using the center bore as the reference.

Also looking at the designs - they're most likely not rigid enough & you'll see errors in fps with the NateChrony. To get the accuracy, I have to detect on a certain part of the pellet, if there's vibrations/movement the front sensor may detect on a different part of the pellet to the rear - at best it'll be variances of ~5fps, worst it'll be 50-70fps (assuming ~500fps speeds).
The adapters will need some form of bracing/contact top/bottom to secure them enough.

Well If I remember correctly 1.75 turns out should be about 145 bar or slightly less
I've used those regs a lot in the past and even made a custom reg tester for that reg

Max out presser on those regs is about 2800-2850 PSI give or take a little

If I were in the market for one I would jump on that, but I just can't bring myself to spend that kind of money for any airgun. Maybe an original Girandoni.

Thats not a good thing to turn the screw all the way in as long if it was only snuged up its OK
You can try 1.5 turns out and up to 1.75 turns to start with this is a good place to start

I can only assume your talking about the black reg with the M-18 X 1.5 threads on it

AOA had one for sale in their classifieds for a few months. They started with it up around $6000, but by the time it sold the price had been reduced to around $4700. I personally suspect that the main reason it didn't sell at the higher price was because the top half of it was a silver color, like it was made of stainless steel and it just did not have that classic look of deep blued metal.

I've got the gen1 metal version and I would also opt for the polymer version were I to do it again. IMO, one of the few flaws that the 400e has is that it's too heavy for a bb gun. That does make it seem more realistic, but I think a lighter gun would be nicer.
