What kind of tuning can I do with the SL30?

I’m learning more and more about pcp’s.. have recently been learning to tune my new Panthera 30 cal 700..

I had given up on my gauntlet because of unrepeatable accuracy but I recently decided to get it back out, bought a less expensive scope for it and I’ll just use it for plinking or use it when the panthera isn’t available (right now I can’t shoot the heavy slugs I want till I get the new tungsten hammer installed on the panthera)

I consider the gauntlet to be an entry level airgun and it’s not worth it to me to dump money on haijimoto upgrades. So what can I do to improve it without a bunch of cash? If there’s nothing I’m ok with that. I honestly don’t have high expectations. I searched for videos on hammer spring adjustments and tuning and most searches lead me to tuning upgrades. But what can I do myself? Can anyone recommend some articles or videos on tuning this thing cuz I didn’t come up with much. Or trigger adjustments for that matter?

Or if had to upgrade something that didn’t cost too much what would be the best bang for the buck? I’m not poor i just don’t think dumping money into an entry level gun is worth it. I have been dumping plenty into the panthera.

Repeatable accuracy will have a lot more to do with the barrel than anything else. Well, at least it does once some quick things are crossed off the list, like verifying the velocity isn’t ping-ponging all over the place, and that pellets are not clipping baffles or the shroud end cap.

If you’re up to investigating the barrel, here’s a link to a troubleshooting and accurizing guide:

The following article is intended for the do-it-yourselfer that is interested in either finding and fixing a problem with a barrel, or improving the accuracy of an already good performer. You don't have to be a master machinist to get excellent results. The techniques described here can be...

The barrels of most budget airguns benefit greatly from cleaning up poor machining, burrs, and other common defects.

This is good stuff.. but I’m not gonna lie some of these practices look like they might be geared towards someone with more gunsmithing skills than I possess although I’m going to look at these.. this article lead me down another road about barrel polishing —>

That is a good process to learn because it reduces lead fouling, which helps a rifle remain accurate for longer between cleanings and reduces the frequency of the occasional flier. However it does not correct for baseline accuracy issues of the sort I think you are describing. With that said, there is no harm in trying but I didn’t want you to embark on it with unrealistically high expectations.

I was just about to buy a G30sl because they are supposed to be incredibly accurate for a budget pcp.From what i can see in YT videos looks like MOA groups at least up to 100yds.Now i’m second guessing that over a Barra 250z for my 100yd plinker🤨

Ya I don’t know anything about a Barra, but I’d choose the Barra… And from my experience pcps are finicky.. I would save up and buy something high end, something quality. I’m very happy with my FX airguns

The upgrades are worth it and after you don't end up spending that much money. $500 for the gun $150 for 700cc bottle $150 for reg $200 tac kit and $100 barrel work which includes opening up the barrel port. That's $1100 and that set up is rivaling $1800 guns and beating out some. From there you could still add a TJ barrel which would be another $300 but still only puts you at $1400 and if velocity is what your looking for that barrel in 30 in or longer would give you that with great accuracyand you would be smoking a lot of them high end guns.

Also, Terminator Industries has a serious tactical and tune kit specifically developed for the Gauntlet SL30!! The kit costs $1,549.00. It called the Terminator Edition. Here is the link: https://terminadorindustries.com/pr...h-mnqq43wRmrVkI9uCu-3T-gkStqOZhufbVpevIQIJorX
Plenty of options for the GSL30. Can be a cheap and accurate air rifle or can be built to extreme.
