Crosman Show me how you moderated your 3622?

Jump to latest Follow Reply
Chief,
I have been using lead free, but the info from posts and reviews is:
JSB 18s
JSB jumbo express
JTS 16.08 (Nibs)
CPHP okay with occasional flyer
Some of these results are for short range and some up to 25 yards.

For 2000psi fill, the first four shots are off. Then they get about 25 to 30 quality shots before the speed and accuracy drop off.
For lead free, I have settled on H&N Baracuda Green 12.96g and Preditor GTO 11.75g., but might change after I try distances beyond 20 yards.

Let us know what you find.

@Gramps Hello Gramps, Good find. Would you post a photo with it ready to fill ( for clearance). The photo they show has a much shorter fitting than my Crosman hand pump. Thanks.

I have the moderator off mine right now & the front blade back on. I use a 18” braided hose to extend the fill hose on my compressor, the fitting on the end is pretty bulky & it fits without issues. Here’s a photo of my hose next to a ruler maybe that will help you determine if your pump will work.

I'm convinced I need to get a foster fitting that is a 90 degree elbow. Just looking to confirm with anyone more in the know about threads. Seems to me the size of thread in the 3622 tube would correspond with....
1/8bspt fittings? The photo shows another type but this should be the general part family.

My moderator is printed at 10 inches, w a long base taper so I can eventually get clearance for substantial connection. I will have to notch it and am likely to use an epoxied no-thread carbon sleeve as the connector, full barrel length plus couple of inches. Seems the best chance for complete straightness that will withstand some throwing around without shifting the moderator.

Also added a 3622 handguard design I'm working on, the hand grip will be removable but its there now for show.

Mine has the AGM moderator. The hamd pump's OEM hose has the moisture filter immediately behind the female foster fitting, which is 18mm (knurled part). It works, but moving the moisture filter to somewhere upstream and out of the way makes it fit easier.

The female foster's knurled knob part on the aftermarket SS hose/whip I bought is 16mm. It fits easily compared to the OEM setup/arrangement. I'm using that, connected to the pump's original hose, which is MUCH easier to manage when filling the gun. (Video of me trying to fill the 3622 with the short fill hose that came on the pump would have had viewers making crass comments about bears and footballs).

This isnt moderation but it involves the same limited area on the gun. Neither of these prints are perfect but they're close.
I think instead of a single new 45 or 90 degree foster I will use a fitting that puts a downward gauge between the bipod legs and then a rightward foster. The left side of this part has a small picatinny for a laser but honestly I'm just going to shed the tinny and splice a tru "laser holder w adjusters" file onto that side, low enough not to be inhibited by a wider moderator.

3rd print is a charm.
