For 1968 production serial #33332, I measure M5x0.8 cheese head slotted black phosphate length 21.5mm for front, and M5x0.8 cheese head slotted black phosphate length 28.5mm for rear, standard walnut stock....beautiful airgun.
...I believe serial #5xxx is post 150 production, and maybe 300 series guns?...I believe front sight retained with a clevis pin, but I've never tried to remove it, but others will know for sure?...
I don't have a 150, but on all 300's and 300S's the front sight is retained by a stout cross pin that you tap out from right to left. It has a tapered flat on one side, the wide end of which is visible as a small gap at the bottom right side; the sight won't be vertical if you put it in any other way!
Four-digit serial serial 5xxx is a model 150 from 1964. Model 300 serials started at no. 50000 at the end of 1968.
some of the 300S have a different front sight where the sight itself is only held on by a dovetail & screw. A cross pin holds a portion of the barrel weight/sleeve then the front sight attaches to that.
Yes, and thanks for the reminder! This was done so that the "Universal" actions could have two different-height sight lines (for which the 300SU was also supplied with two cheek pieces and a rear sight riser). It's also nice to be able to remove the front sight for scope use.
The securing pin was also moved to the bottom of the sight housing.
@mdriskill and seemingly another variation, on my Match L & Tyrolean. No retaining pin on the top but another one on the bottom and no dovetails to remove the sight...

Not positive, but I think the bottom retaining pin became standard for the longer fixed-tunnel sight housing after they started with the U's. It would have simplified manufacture by using the same barrels on all models. I suspect the two interchange, but I've never tried it.
For what it's worth, top-to-bottom in this pic:
+ 300 no. 636xx (1970). Straight sleeve, short top-pin housing for fixed tunnel.
+ 300S Match no. 1386xx (1974). Stepped sleeve with long fat section, long top-pin housing for fixed tunnel. (300S barrels are 50 mm shorter than the 300, the stepped sleeve adds front weight to restore balance.)
+ 300S Universal no. 3034xx (1980). Stepped sleeve with shorter fat section, long bottom-pin housing for interchangeable tunnels.
+ 300S Junior no. 3729xx (1991). No sleeve, short top-pin housing for fixed tunnel. (The Junior / "Mini" barrel is 70 mm shorter than the 300S.)
Close up of the Mini front sight. It appears they were cleaning out the old 300 parts bin, LOL - it is identical to the sight on the older gun, though the finish is different. And...note the barrel is cut for EITHER a top or bottom pin! You can also see the odd tapered-flat securing pin.
Does the front sight on the 150 retain the barrel sleeve in place, as on the HW55 or LG55, or is the sleeve glued on as on the FWB 300S (I think?)?
I can answer that with a resounding, "I don't know!"
I have two 300S's, on which the sleeve is most definitely epoxied in place. But the sleeve is loose on my 300 - I don't know if that was the factory standard, or if the sleeve was added as an accessory later.
And I don't own a 150...
PS: Just saw your post above, which tells me my 300 sleeve was probably a later addition. Thanks!
Hello, I know this is a little off subject, but you guys seem very knowledgeable about the 150's and 300's. I did a search on the matter and came up with nothing. My question is: Is the 150 un-cockable. If so, what is the procedure?
@landmass Not sure what you are driving at. The barreled action pictured does cock and engage sear. How ever there is something with the trigger mech thar don't seem right. When I received the 300 stock I set the action on it just to see how it felt. it does need to be modified (the stock), in order for the cocking lever to fully close. 150 action long cocking lever, 300 stock inletted for short(300 lever). S o when I set the action on it would not nest as it should. When I went to shouldered the set up the rifle discharged a pellet right into a window. When I first got the 150 action I must have cocked it and installed pellet and found it would not discharge. What now? must have set it in the corner and forgot about it. Not good on my part and kind of figured it had to be in a stock to release sear. I need to get this up and running but am having a difficult time deciding to mod yhe stock and then find out it don't work.
