Some of you may remember that I was making and selling these PCP kits to mod your 1377 or 1322. I had sold a bunch on Amazon and ebay but it's hard to make a profit when people will add the cheap Chinese ones to their cart first so I wasn't really able to recoup my time in my list price so I pulled them down.

Anyhow, with the factory valve and an updated valve seal, they will hold way more than 2000psi but thats where I had them rated at because valve lock would occur at anything higher but I just FINALLY got my patent pushed through and now this thing will work just fine with no valve lock at 3500psi using my new patented poppet. I typically keep it at 3250 and I'm pushing 20 grain slugs at 838fps (not bad for 22 caliber.) I don't want to give a descriptor just yet at my patent technology because I plan to sell the valves on ebay. This valve tech will also work on all PCP guns that experience valve lock above their rated pressures so hopefully I'll be able to expand this with other manufacturers in the future.

Pictured is my 1322 with said valve and moderator that I designed and 3d printed (It works really well.)

Power sounds nice, but what's the shot count on that small cylinder?

I have 3 of those Chinese drop block builds now, and they have exceeded my expectations. I opted to cut down 2240 tubes and reuse the stock hammer style setup. Just need a carbon sleeve to bring the breech height to the right level.

Even on a 100cc Chinese tube, they get a ton of shots since the fill is up to 4500 psi. I run them 3500 or less usually, since it's hard to get enough spring behind the hammer.

Why the 1300 series and not the 2240? You evidently change the bottom tube wouldn't it be easier to extend a 2240 tube? Just curious I have an old 1377 and might try what you guys are doing. Here i my 2240. Still on Co2 but getting around 525 fps.

I made pcp conversions for the 2240 also but that Froggy? guy is making them too cheap for me to make and sell. Of course he's using aluminum and not steel so that's why (easy to machine).

If I remember correctly, with the factory valve and no other mods, just using my pcp conversion and a 2000psi fill, you would get 20+ shots on a fill.

I spent 1 hour today researching some PCP conversion options for the Crosman 13xx/22x.
These are the best options I found:

Security Measure

www.ebay.com www.ebay.com

I found unregulated drop blocks for $61 and regulated drop blocks for $76.
I found some other options which also included an air tube, starting at $60 and going $100+.

The cost of the gun (Crosman ...) and the PCP conversion will make this entire setup more expensive than existing PCPs, which have metal receivers, magazine and other goodies.

This Beeman 2027, which outshoots all the Crosman 13xx/22x, costs about $100:

I am done with this nonsense.
The Crosman 13xx/22xx should stay as they were meant instead of making them 3-4 times more expensive.

Some people don't want to own a cookie cutter product that everyone else has.

I agree with Nobody on the economics. You can buy a better product for less. You will not turn a 1300 into a Notos for what you can buy a Notos for. But there is a large segment who already have the 1300/2200 platform and would like a little more. Adding aftermarket parts and tuning it to shoot hard and accurate is a challenge many enjoy. Thats the allure for me. My next one will be a PCP build but in reality you keep very little of the original gun. The valve needs changed or altered, springs, TRIGGER , air chamber and barrel. Barrel costing more than the original gun. But still you are taking a gun you seldom use and turning it into something you enjoy. Thats the economics of it, you were going to spend it on something anyway.

Some want to tinker and some want to shoot.
We should welcome both!

I have been guilty of tinkering myself, I just try to keep it cheap.

Those beemans are also heavy, no part support, and sound clunky as hell when fired. I've owned a few. The 2028, the chief, chief II plus, and the 1358. All throw away guns. All had accuracy issues as well.

I'll keep building my tinker toys. Here's one with the $60 drop block that I modified to fit the standard tube vs the rear cocking hammer they come with.

Did it cost more than a beeman in the end? Yes, but I'd rather have this than one of those any day.

I will have 4 Crosman pistols as long as I shoot airguns, 1377, 1322, 2240 (10" barrel), 1740 (10" barrel).

Stock, they are great, cheap plinkers.
And I plink a lot :)

I am just saying that for the price (including the upgrades) you can get much better PCP pistols.

Some of you were born to tinker, no matter the price :)

That's why I sold off my daystate Huntsman. I couldn't tinker on that and didn't want to ruin it.

Yeah, I'm that guy. Sells a $1300+ rifle and keeps his $100 money pit pistols lol.

Yep... I place a pretty good value on the "tinker factor". Yeah I know, I'll never get back what I put into them but who says I'll ever want to sell them.
Lots of people call them the "lego" guns. I prefer to call them the Erector set of airguns. I can't even count how many times I've had them apart and back together in some other form. I even have a pigeon hole drawer rack of parts for them.
