Part 1
Part 2

Today’s report contains special instructions for the disassembly of a Feinwerkbau 150 air rifle — for those few places where it departs from the FWB 300 instructions presented in Parts 1 and 2. It was translated and written for us by reader CptKlotz.

If you’d like to write a guest post for this blog, please email me.

Over to you, CptKlotz.

This report covers:

  • Additional information for disassembling FWB 150 rifles
    Trigger blade
    Ratchet unit
    Powerplant disassembly — potential danger!
    Procedure

This article was originally published on the German co2air forums (www.co2air.de). It was created by the users Pellet (original text guide), Paramags (additional information and FWB150 details ) and boerni (photos and forum post). They kindly gave me permission to translate their guide so people who can’t read German can use it as well. The original forum post can be found here. read more


Industry Brand B3-1 – Part 3

by B.B. Pelletier

Part 1
Part 2

This inexpensive Chinese underlever has been around in one form or another for many decades.

Today, I’ll finish the report on the B3-1 underlever rifle. I did this report for C-S, who now goes by the handle Milan, and for a couple other readers who said they wanted to know something about these older Chinese airguns. We ran Mac’s report of the Weihrauch HW97 underlever at the same time, so if you wanted to compare the two rifles it was possible. Actually, there wasn’t much to compare — just a lot to contrast, because these two air rifles couldn’t be farther apart.

I shot the rifle from a rest at 10 meters because I wasn’t confident that the rifle could perform at a longer distance. At least at 10 meters it would stay on the target paper. I used the artillery hold with the rifle rested on the backs of my fingers for maximum stability. read more


Industry Brand B3-1 – Part 2

The August podcast was posted on Sunday. Sorry it was late. I apologize for the weak sound of my voice. I actually feel stronger than my voice indicates. I expect things to return to normal some time in the near future. Now, on to today’s blog.

Part 1


This inexpensive Chinese underlever has been around in one form or another for many decades.

Today, I’ll check the velocity of my B3-1. I’ll also check a couple other things for you. Cocking effort first.

Cocking effort
I mentioned in Part 1 that the cocking effort seems high for the power range of this gun. Well, it tested lower than I expected, so I’m just a weakling. To test the cocking effort of an underlever, you place a non-digital bathroom scale on a table and position the cocking lever near the middle of the footpad on the scale. When I did that, the rifle took 31 lbs. of force to cock. I would have sworn it was above 35, but the scale doesn’t lie. I do believe that if the internal parts were deburred and properly lubricated, the effort to cock would drop by a couple of pounds. read more


Industry Brand B3-1 – Part 1

by B.B. Pelletier

I’m writing this report for C-S and for all the other readers who ask about the Chinese airguns. I go back to the 1980s with the B3 design, because I bought one of the first ones through an ad in American Rifleman in the mid-1980s.

That rifle was the epitome of crude! It had poorly finished, poorly fitted metal parts sitting in a pallet-wood stock finished with too much orange shellac. The front sight was rotated to one side, and the synthetic breech seal was cracked and flaking off. The metal parts looked as if they had been dragged behind a tractor a few days, then given a blue from the 14th use of the salts. The word I’m searching for is disgusting. read more
