Sight help please 2240 crosman

[Gerrygg]

You need a nice GMAC brass silencer adapter with front sight pin.

Another way to "silence" the 2240 a bit is to cut down on the striker spring.
The 2240 wastes a LOT of gas after the pellet has left the muzzle, because the striker bounces on the valve.
Cutting down the spring within limits will not reduce muzzle velocity very much, and reduces both muzzle blast and gas consumption.

I've heard this many times and must get round to doing it to mine one day.

And I should get around to do a spring/velocity comparison.
I have a couple cut striker springs at different lengths, so a chronograph session with different springs should give numbers that can be used if other people want to cut down a spring without going too far.
One thing you have to bear in mind is that a cut down spring could introduce some valve-lock at high summer temperatures.
Other than that its a win-win-win situation: less cocking effort, less gas consumption, less noise.

Such a comparison would prove very useful and interesting, evert. I guess temperature would also have to be an important consideration.

Re the weaker spring on the shorter barrelled 2240 (as opposed to the 2250 models), I wonder if the reduced muzzle blast may help accuracy a little?

Also, at what point may too weak a spring affect CO2 capsule piercing reliability?

And the, once again, I have the humbling experience of my memory not being what it used to be.
I have a lot of different springs in the box of crosman parts, but cant figure out which is an original 22xx spring, which is a Benjamin discovery spring, which is a 1377 spring, and which is just something I put in the box several years ago because it fits the guns.

Does anyone know the dimensions of the original 2240 spring?

yes I had seen that
Please, note the thread is M14 CCW, but not 1/2" UNF ! so no good mate thanks for trying though

Crosmans can be a money pit.

Fit a scope?
They do plastic blocks that clamp to the barrel to give you a dovetail fitting. Work OK ish, but very easy to knock the scope off zero.
Fit a steel breach and fit a pistol scope?
Or steel breach, Crosman stock, and something like a Simmons – 1.5-5x32.

Mine has SAK moderator, steel breach Nikko Mountmaster 3-9x40, Crosman Stock, replace trigger spring and add spring guide, polish sears.
Pellet on pellet at 8 yds, very quiet apart from hitting the target, 1/4" group standing, unrested, with a kind of 2 handed pistol grip.

Drill and tap an M3 hole in the silencer adaptor - screw in an M3 screw and lock it off.
Or even just use a small jubilee clip to attach a bent bit of metal to the body of the silencer adaptor.
Depending on the diameter of your silencer you may need to make the front sight taller than the original and in that case you may need to make a longer rear sight blade to match.

I have done exactly this mod myself - works fine.
