500 fps limits

Yes the Williams is very nice,,haven't seen the back of it,,does it have the quick find white dots like the LPA,,haven't really gone that far and have both in mind,,what front sight are you using and is the notch in the blade wide enough to quickly find the front sight,,it looks very narrow,,was thinking of the Crosman black front sight with post but no holes to cut down noise,,been a very long time since I've shot a hand gun and getting into this is mind boggling with all the mods,,the only reason I did get into it was because 3-4 times in the summer we take off and travel way back roads all over the interior doing photography,,it's just a toy to play with when stopped for lunch and play a little.

So it's the name given to them..muzzle brake,, that allows the user of an air pistol to attach it to the end of the barrel.

Couldn't find much on the hollow probe in a search,,can see where it would help,,I think but is it worth the cost and effort to put in,,copied and pasted the discription below.

Extended hollow probe for use on Crosman 22xx, Discovery airguns. Reduces resistance to gas flow between transfer port and the rear of pellet.

I used an extended probe in a 2240 build, and it works great. Not sure how the hollow ones fare...
X2 on the Chrony-well worth the investment (less than $100).

Have got my mind working again and have to settle it,,I like the long 4 or so in. brass muzzel brake with front site post on it and holes around that the tops are enlarged,,mailed a dealer down here and asked if they could order one on a request from me,,don't know how that'll go over,,probably not,,just want to cut down the loud report everyone say is,,have access to a lathe and milling machine and a friend who is a master at it,,I know the barrel is 5/16 and he can drill it to it,,put the holes in but the end looks like it's maybe a slight touch bigger than the riffled barrel diameter,,if there is enough length going over the barrel and it's tight for about 2 in. that should keep everything in line,,2 set screw to hold the brake tight to the barrel,,looked for designs for that particular one but they don't give them up easy,,can laser front to rear sights with no problems before setting lock screws,,,,anyone have any good schematics or drawings on this project and or will ship one to Canada.

In my view (and I sell these things) the hollow probe is a waste of time on anything less than an 18" barrel- the 22xx's flow more Co2 they can use with shorter barrels in .22 caliber- and even at 18" it's usefulness is debatable.

I replaced the hollow bolt probe on a QB78 with a Crosman style extended central probe and picked up over 30 fps on a 30 FPE rifle on HPA.... BTW, I had previously enlarged the ports in the hollow probe for maximum flow, there was little wall thickness left.... I personally don't like hollow probes....

100%

After having some trouble with my hollow probe, I made up an extended one and like Bob said: picked up 30-35 fps. Eric has both the hollow probe as well as the Crosman extended probe, you'll just have to decide which one...

And to echo everyone's suggestion - purchase/borrow a chrony!!! I would be lost without mine.

Well I guess that answers that,,the Williams Notch Blade rear sight looks very nice,,but would have to make or buy a muzzle brake with a post on it,,a scope does sound nice but it's iffy for me,,haven't even got the ****** yet and already thinking way ahead of myself,,haven't told the wife as yet but will get into my sulking mode when it comes,,got to think of a good face to put on,,had problems when younger with my hand guns,,maybe I can play it down and say it's just a pretty BB gun,,got a week to practice and at my age that's a long time,,HA HA

Don't assume a 14" barrel puts you over 500 fps. I didn't crony my 2240 until AFTER adding that barrel and a small bit of tubing behind the spring.

To my surprise it clocked between 493 and 497 fps. So that particular 2240 was doggish from the factory to begin with.
