Randy, I've been lucky enough to successfully repair some Benjamins with this setup without needing to replace the outer valve O-ring #2621 - but here are a few thoughts that may be useful:
1. Some folks use a home-made thin-wall 'hole saw' to completely remove the old, hardened O-ring (as in the video). Installing the new one can require a lot of force to compress it into the crevice - another thin-wall tool and ample lube should help, maybe some persuasion with a mallet. Note this is the same O-ring #2621 as used on the front cap.
2. Polishing the valve seat is critical - any blemish or corrosion will cause leaks.
3. The softer seal in factory-style exhaust valves may achieve a leak-free situation more readily than a harder Delrin version, by conforming to any tiny irregularities on the seating surface.

Good Luck!
Don R.

Zeke, some of us take offense to using the name of the King of Kings and the Lord of Lords name like this. It's very disrespectful and I might point out is not cool at all, no not the least bit funny.

Keep in mind He's the same one and only true God that you'll give an account to someday. A God that humbled himself to come in human form born of a virgin, because He loves you that much, payed the price for all our sins with his own blood, was raised from the tomb because it couldn't hold him, was seen of many on earth after that for a season, then ascended to Glory.

He loves you Zeke.

So this approach is somewhat similar to the REPR regulator on the Leshiy2 where an external pressure gauge can be screwed in and a special tool is used for regulator adjustments (done externally on the L2). I'd have preferred a permanently mounted regulator gauge on the Slash along with an external control for the regulator which didn't require removing the cover plate first.

Many people will be satisfied to find a sweet regulator/pellet/fpe combination for hunting and leave it set for consistency.
I prefer to vary the power settings more frequently, bouncing between lower to reduce the sound levels for close targets, and higher to test FPE & performance for different pellets.

The need for an additional 'power kit' for extra low (under 12FPE ?) or higher than standard power settings surprised me at first. Though I've changed out enough washers in output regulators on air tanks and swapped out hammer springs to understand why is would be necessary for the more extreme settings.

Two other questions of big interest to many concern the sound levels. Not only do we need some accurately tested sound results at different FPE levels, but also some customer feedback whether or not there is a substantial Ping or other loud noise made close to the shooters ear on firing. I ended up selling my 1st bull pup because of an unacceptable ping/bang/whoosh noise next to my ear when firing. So far I haven't heard any 1st hand impressions on the new Slash other than vendor assurances that it has an effective shroud.

I think that the Huben K1 does pretty well on both of these sound questions, and the standard Leshiy2 shroud works pretty well at lower powers. I am very curious for a direct Huben K1-to-Slash sound comparison since I view the K1 as the main performance and cost competitor for the Slash. The L2 has substantial noise and air flow back near the the magazine when fired. But the shooters ear isn't resting on the L2's stock near the magazine when shooting, so it doesn't sound all that loud to the shooter compared to a loud ping from some bull pup designs. The L2 and the Slash both occupy similar price ranges when new, while a K1 costs about 25% less than either of those when new.

It'll also be interesting to see how many Slash end up in the classifieds a year from now. There was a wave of Leshiy2s in the classifieds for awhile as early buyers moved them along for something else. Lately is seems like there are fewer L2s on offer. And K1s come up for resale in the classifieds, though it seems to me like slightly more GK1s on offer recently.

It'll be another year or two before we know how well the Slash model line will hold up. Sometimes I see posts by younger (than me anyway) airgunners asking why anyone would be selling their 'almost new, top of the line' airgun purchased within the previous year. It isn't always because the owner was dissatisfied with the airgun. Many of the people who buy 1st release airguns are older and money isn't the big deal it was for them as young adults. The clock is ticking for them and now they can finally afford to own a bunch of expensive airguns all at the same time. They are often more interested in checking out a new product than in actually using it for anything, especially since they usually have a few fine airguns already gathering dust from lack of use. So they buy and sell a few airguns most years just to keep things interesting and they don't care very much if they sell at a loss. Churning through airguns is just another entertainment cost for them, and any money lost from selling an airgun is merely a rental cost for being able to own another fine airgun for awhile. Personally, if I had my choice I'd rather be young and broke again. Well, young anyway, the broke part was difficult.

Now, if they'd just get busy and design these *** airguns so they don't use any O-Rings that can fail. Firearms manage that with vastly higher internal pressures and usually for a considerably lower cost than airguns. I hate replacing O-rings, they are the main reason that most airguns cannot be depended on to perform 100% of the time in emergencies.

Hey, that's my local range! I'm still tuning my new Blackwolf but I intend to join you in benchrest someday. I'm going to try NRL22 as well, when I'm ready.

How was the weather for the match? Crazy winds lately.

Hello Nation,

I'm looking for an o'ring set that will help keep my rifles up and going. I am aware that there are vendors that sell reseal kits for certain rifles, but I'm looking for something more comprehensive and less specific. I have a Zelos that lost 500 PSI overnight, so I need to identify the leak. I also have three other rifles that will inevitably need o'rings in the future. Any recommendations?

I faced the same situation as the OP: too many groundhogs and close neighbors. Experience hunting groundhogs in my youth with a 22LR taught me that they are tough to kill cleanly unless head shot, otherwise they will run off and die elsewhere - not good if they make it to adjacent property.

For this purpose I ended up buying a Benjamin Marauder PCP in 25 caliber. It is tuned to 45 FPE and has been effective on groundhogs to 55 yards (longest yet). It is very accurate, easy to shoot well, and quiet with factory "barrel baffle". It is quieter than my HW95 with moderator. The Marauder is an established platform and there is a lot of knowledge and accessories available. Downside is that it is very heavy and in total expensive.

In parallel with the Marauder I also use a Havahart single door live trap baited with cantaloupe or watermelon. Make sure to stake it in ground or they will turn it sideways and escape (don't ask me how I know). Most springers springer can dispatch them once trapped. In this way you can buy a springer that's fun to shoot, is within budget, and effective on trapped groundhogs.

If you lived here in California, near Fresno, you would never say you never had an A/C in a 100 year old house. I grew up without A/C and swore as a child that on day I would live in the lap of luxury with an A/C in both my house and in my car...and I would use em both as much as I wanted!

Yes exactly, regulated pcps are more consistent from shot to shot, the Fps stays even, and the shots hit the same spot one after another. This is even more so the case with dual regulator guns. I have several non regulated guns, several regulated, and one with dual regulators. Non regulated guns perform best when tethered to a tank for shot to shot consistency, you get a ton of shots at similar fps
