Daisy Model 188 BB Pistol Disassembly, Part 1

I've been a bit busy lately but decided it would be fun and quick to take apart my Daisy model 188 BB pistol and see what makes it tick. Mine is the metal bodied but BB only version.

The pistol.

The loading port, you can see the BBs being picked up by the bolt here. On the earlier model you could also insert a pellet but the casting was changed to prevent that.

4 screws, 3 of which are identical.

The halves separated.

The sear was heavily crusted with dried grease. Note the spring.

The bolt. The tip is a magnet.

The cocking lever slips off of the post and the wire rod.

That wire rod opens the bolt when the pistol is cocked.

The sear and trigger.

The wire rod.

The compression tube, spring and lever can be removed as a unit. It's under a bit of tension inside the pistol even uncocked.

The piston slides out of the tube.

The end of the compression tube is injection molded plastic and also has the transfer port seal.

The piston seal. Pretty much conventional parachute type seal.
More to come...

Dude, I could use some help. I took my 188 apart, but I have a spring that jumped out, and now I don't know where it went inside the gun. I know there is a spring inside the bolt mechanism, and that there is a spring inside the safety, but I have another spring that is a little bit larger than the safety spring left.

Don't know? Could be the trigger spring?

I have an older daisy 188 which shoots pellets or BBs. can something be done to make the compression stronger. i mean when i cock my daisy 188 and insert the bb or pellet it will go but the compression is not as strong as it should be. is there something i can do such as replace the o rings to make compression stronger on this gun. mine is the older version and shoots pellets or BBs. does anyone know how i can do this or what needs to be changed to make the gun shoot further like it did when it was new.. any help would be appreciated..Please advise

I don't know if you can get a replacement seal for it, you can try:
Bryan and Associates, Mac1, Precision Pellet or JG airguns.

Tell them I sent you.

Have the same problem that Fred
had on 29 April 2010. I have no
clue where that little spring goes.
I think it may be used to keep
tension on the cocking lever.
Help please.

The larger spring is indeed the spring that goes by the cocking lever. I was confused as to where the second smaller spring with the ball on the end went. You helped me so this is the least I could do. Cheers!

JJ said...

im having the same problem as bill. Opened up the 188 and a small spring fell out. I would appreciate if some one can explain to me where it goes.

hopefully you found what it was for , if it's real small could be the safety spring , or the spring that's for the pump lever

Hey guys, the spring is simply akeeper that goes between the barrel housing just under the cocking front screw.It just sits in the set between both halves and gives a little click when the
leaver closes

Bill said...

Thanks YoyoDriver. Now if I can
find the spring and the time to
fiddle with it!!!!

Could someone please tell me where I might could find the little sliding door, where you insert the BB's on a Daisy Model 188? Any info you may have would be GREATLY APPRECIATED. Thanks.
