    "bam" underlever air rifle what model is it? Is it the same as smk ?

    Hi learned members, I was given an old Chinese underlever air rifle in .22 cal. All in bits I have been told its all there, but it does need attention !! So I re-assembled it -- it cocks but the trigger sear does not engage positively and hold back the piston, which has a tendency to slip off as returning the underlever. The piston sear ramp did look a bit worn to be honest. I was told these are the same as a SMK db4/db5. So I ordered a new piston from T.W. Chambers but when it arrived this morning it measures 20mm longer. I have been trying to identify the exact model but the only marking on the action is "BAM"
    the stock is a bland painted plank with a non defined cheek piece and an over sized hand grip which puts the trigger almost out of reach. The front sight has a single adjustable post inside an open hood, bit like the ak47 looking on the net all indications are of a b3- ? but there are so many variants. When ordering the piston "BAM" as a make is not available so went for the SMK db4 anyone had any experience getting parts for one of these old guns ? Chambers have said that because it is an old model they cannot help me any further. I have decided to see if I can get someone to splash a weld across the rear of the piston skirt and see if I can re-file the sear angle to suit.
    If not I will put it up for sale to recover my outlay for a new piston seal. stock refurbishment paint job & postage costs. Around £35 + P&P Cheers mickey

    B3's and B4's are similar and made by just about every Chinese airgun maker. The B4 trigger angles forward from the upright and makes a stretch to reach it. These are a one piece blade. B3 and B5 triggers are the same and hang straight down. These have a join to give the impression of two-stage trigger.

    God the mention of that name made me shudder, I had one of those years ago, it was the most horrible thing ever. Very inaccurate, rattly and with the noisiest anti bear trap mechanism ever

    Not with BAM stamped on it. Two different companies. The Lion and Arrow models were pre B3/4's.

    Read text correctly "made FOR Germany". They were made in China like the rest. They have a completely different trigger design.
