Bigger spring? bigger compression chamber? The B4 is more powerful...right?

B3 better trigger more delicate. B4 clunky but alright and takes some shots to get used to. B4 seems like more robust after tune. B3 more finesse with slightly better barrel. I think the B3 chasis is similar to my AK-B3 trainer, same spring and tube. B4 is underlever. I believe B3 has a side lever and under lever configs. Milehighguy is the main man on these variants. Get and extreme custom from him and you will have a decent springer.

I never knew the difference either until Ora posted the dimensions of the 2. I believe the main difference is that the B4 has a shorter piston which increases swept volume which increases the power. B4's are made by Xisico which means they have somewhat better QC. Do a search ( if you can, when I search I end up reading what seems like every post there ever was). If its possible search for a relatively recent post by "Ora". I have a B3 but not a B4.

B-3 seems to be the most 'Generic' name of Chinese air rifles. Said model is made by several companies. Most are under-levers and at least one side-lever. B-4 of which there are several variations. It I believe is a big brother to the B-3, exactly which B-3 I'm not sure.

I think B4-2A is only in .22 and only underlever with a wider piston, exibits more power. B3 has alot variants. underlever and side lever. I think my AK B3 tuner is the same upper part of a side lever B3 and think it goes nder the designation of b3-3. As for quality of shooting the B4 's exibit a very "thud" wallop while the B3's are more finesse with a better trigger. For target shootig and small pest control I like my B3 gun .177better. For cans and mass destuction the B4 .22 is the ticket

And they are only slightly related.

The Xisico "B3" is the "XS-B3-1", and is a sidelever AK-47 styled gun, around $60 or so.

The Industry "B3" exists in B3-1, -2, -3 and -4 variants, all have the same advertised power. B3's start at around $20.

They use the same general principle of a sliding pump cylinder and fixed barrel, but they are different enough that you can't really call them variations of the same gun.


There are also 2 B4's -

The Xisico B4-2, which is the popular underlever style commonly available for around $30

The Industry B4-1 is a sidelever that seems to be mechanically related to the Industry B3.


I imagine you're talking about the most popular - the Industry B3 vs. the Xisico B4-2A. In that case, the general consensus seems to be that the B4 is stronger.

Thanks guys good info. I ended up with a B3-F from a tool sale. Never heard of a B3-F. It has a monte carlo stock that was stained with a thick layer of clearcoat on it. Also had grooves cut in it for scope.

Vince,

You missed the 'Snow Peak' B3 series of which the Cummin B3 is made.

As I understand it, they are now Industry B3's. The Cummins "B3" I got a couple of years ago was actually an XS-B4 with the proper AK-style front sight, but a dovetail mounted, thumbwheel-adjusted rear sight. And a seriously mis-mounted barrel (which I fixed by sitting gon it!).

Dunno about the Snowpeak... but I doubt it's anything more than a rebadged Industry gun (like the old "Pioneer" or "Westlake" S-2 pellet pistols).
