This was from Utah Airguns they had 20 or 30 of them they sold out in 15 minutes
if you want one get on someones pre-order list you have better luck with smaller sellers

The more I think about it, the less likely I am to get an 800mm barrel kit. This is just my logical mind talking here.. In my case, I'll basically be paying $400 so I can have another 30-40 fps on the very top end. I've already gotten my Maverick up to 90 fpe. Is there anything I can't do at 85 fpe that I can do at 95 fpe? Of course, it isn't all about the top end. The gun will likely hit the 75 fpe range much easier, and with a better shot count. Is there a huge advantage to shooting 40 grain slugs vs 36 grain slugs? If I were in a different place financially, it would be much less of an issue. I'm just at a point where I'm having a hard time justifying spending $400 for some minimal gains and gun that may not fit my case anymore.
I'm not saying I won't get it at some point, but my brain is talking me out of it at the moment I think. Don't get me wrong, it would be very cool to be able to say I was able to hit 95-100 fpe with my Maverick in .22. Is that really worth anything to me other than saying I did it?
Anyone know if impact barrels will fit in RTI PROPHET what is the diameter of the m3 barrel
...Is there a huge advantage to shooting 40 grain slugs vs 36 grain slugs? ...
Just get one of those sleeve extensions to extend your 700 to an 800 and buy the liner only....
Well, according to strelok and assuming those 31 gr nsa's you are mentioning are about the same lenght as 30gr HN's with the 1:14 you 'll be getting a stability factor of 2.5 to 2.8 from 820 to 1000fps so from what i understand it is a bit overstabilized but acceptable. If and when i get that barrel i will post some more feedback from 40 to 25gr testing
bigHUN here you go
So the 800mm liner arrived and here goes my experience so far.
I was surprised to open the package and see an indexing mark along with a liner stained with mud or oxidized on the outside and polished on the inside so all pointing to a used barrel.
But has always i make best of what i have so on with the setup.
Using the same original 600mm outer barrel with some extenders with no gap to double has stiffeners and some custom shroud that is in the future to go along with a custom scope rail i am cooking for some while and a airstriper that flows into the shroud that acts has a tensioner (like fx one but mine is older)
I only tested the projectiles with a carbon fiber barrel sleeve (not the fx one) the ones i am using are pressed into the liner further adding stiffness.
Good news! This liner shoots both .217 and .218 at the same speed so there's lead coming. At least with the projectiles i have. Showed more promise with the .218 but later that day i went back for the .217 and groups matched equally.
I tested with and without the shroud at 130bar so i only expect any difference at higher pressures. Max Power output at 130 was 70ft-lbs. These were the first groups shot with different slugs. And for now i plan to use this barrel with 30gr and up. And the pellet liner for 25 and below.
Just because the norica slugs in 25gr needed added weight at muzzle to group well and by well is at 50m a 5 shot must touch between each other.
1st group 25gr norica. Left one is aim point. No need for excuses its just i grab anything for aimpoint so im lazy shame on me for not using paper targets.
1st 5 group hn 30gr .217 left is aimpoint Yes there are 5 plus 1 for aim.
1st 5 group with hn 30gr .218 left is aim. Bottom was already there.
1st 5 group with zan 40gr .217 left was aim ignore rest outside the group. This Zan after tuning velocity were as the .218 hn. One small hole.
The main goal for this liner was to stabilise very long slugs. And it really does, even at much lower energy.
The 40gr zan had a higher bc than announced in strelok at around 880 up to 300m working on placing longer targets now. It was perfectly capable before with 25gr slugs, but they were very influenced by low wind at that range.
Tested both the 800 and 600mm at same 130bar speed difference is has shown in the photo. P is the position of the hammer pre tension wheel at the back. (Mine has20) the number left is the projectile weight in grains and the arrow with a number beside it is the poi difference.
Hope it helped anyone ou there.
