Since we seem to be on the topic of B3s

[pyrophreek]

Have some general questions and a few comments about the B3 rifles as I just got a B3-3 from south summit and home tuned it.

1) what effects have people noticed from adding more or less tar onto the mainspring? Does more tar lower the hold sensitivity?  How much tar does it take before you noticed difference in performance?

2)  Has anyone tried the Leapers zytel clip on bipod? ( http://www.pyramydair.com/s/a/UTG_Zytel_Clamp-on_Bipod_for_airsoft_guns/773 )
      specs say it will fit on the underlever of my B3, and it seems like that could be a nice cheap add on.

I noticed that the B3-3 I got is a little different from the B3-1 in that the cocking lever doesn't have a handle on it and snaps into a clip.  Also when I took it apart, it came with a synthetic seal and when I compared the mainspring to the one in the QF2 parts kit it was identical.  Has anyone had both a B3-1 and B3-3? what other differences have you noticed, and which do you prefer.  Also how do they compare when you shoot them.

Kimball, to much tar will slow your fps down. When applying tar it sould be spread evenly across the coils. Excessive tar is not necessary.

Reading the reviews of that bipod at PA, they say it's not really made for a heavy gun.My B3 is most certainly a pretty heavy air rifle.

As Gene mentioned a load of tar isn't needed for the B spring, to much of it will end up migrating off the spring and possibly gumming up the works so to speak. :0 As far as a bipod I have one on my Sniper style B, works great. Check the mounting location on the barrel, it may mess with the harmonic's. Mount it then run some lead through to see if the POI changes any. Ed

Actually the B-3 is not that heavy compared to full size springers. Ed aka "Shadow" has numerous setups on his B-3's for specific hunting chores. He is the best source on the GTA for B-3 information.

I have a old B-3 but the pull needed for the trigger is so great that you almost need 2 hands. Can anything be done to the trigger without taking the rest of the action apart? If so, is there a diagram somewhere or instructions? Thanks!  Terry

I have two newer ones.One has a darn good trigger from the factory-the other not so good. Someone will chime in here about the triggers, but I have heard,if you remove the action from the stock, it's possible that one or more trigger pins have slid part way out and might be rubbing on the stock causing a lot of resistance.

The B3 trigger can be removed without pulling the action apart. Remove the action from the stock, flip it over and just push out the small pins. The larger pin that hold's the sear in place has a keeper on one side that you will have to pop off, don't lose it when it pop's off. Now just lift the trigger and sear out. Here's a pic of the major polish point's circled in red to smooth out the trigger pull. You just want to polish these area's without changing the angle of them, if you alter the angles it can make the shooter unsafe and possibly go off do to the sear not holding the piston correctly. As for myself I polish the whole trigger and sear including the spring and inside the pin holes, it makes for a silky smooth pull. I do this polish method to "my" trigger's only because I've learned the in's and out's of them and I'm not suggesting or recommending that others do the same to their trigger. Take it a little at a time then pop it back in and do some testing but always be safe gang. Ed

as jon noted, i had this very same problem with one of my b3s.......as luck would have it one of the trigger pins had walked out of the reciever. replacing it and lock-titing into place cured the stiff trigger.

[Traolach]

Ed, thanks for the instructions and the diagram. Do you put any grease anywhere on the trigger before you put it back in?  Terry

[shadow]

I just put a very very little amount on the pins and larger pin so that the trigger and sear glide around them. The polishing does the rest as far as the trigger and sear engagement are concerned. Ed

[Traolach]

Ed, I am missing a keeper on the large pin and one of the small pins too. Is that important?  Terry

The large pin has a groove in one side that the keeper pop's into.This pin hold's the sear in place and I would suggest a keeper on it. I don't know of any other keeper's on the other smaller pins, one hold's the trigger in place and the other go's in and up and behind the trigger. Some have another small pin that go's forward of the trigger also. If you need a keeper for the large sear pin let me know, PM me your addy and I'll send one your way. Ed
