Hey all, I'm back.
As promised I just came back from a trip to the range (video to come).
I'll try to keep this short and sweet and give some good constructive criticism.
Disclaimer: These are only my experiences and opinions. I did take it apart and put it back together, so please keep this in mind.
THE GOOD:
Shotgun works!
Yes, I was able to put approximately 80-shells (Trap#7's and 00-Buckshot) into the target/burm with little effort.
The 5-rnd magazines worked well, the 10-rnd magazines were very stiff stripping off the top 3 shells, but from then on the ease at which the action worked was comparable to that of the 5-rnd Magazines.
That's really it.
It works and that is good at the end of the day.
THE BAD:
I've probably spent at least 6-8hours looking over this shotgun and trying to decide what to do with it. As I said several time, it's beautiful. The receiver looks very well made as does the bolt and bolt slide.
I never doubted that it wouldn't work. My gripe was with the build quality of certain parts (i.e. Springbok and magazine-modifications.)
The magazine modifications: My only beef with the mags really boils down to the "machining" used to modify each mag.
The magazines also do not lend themselves well to rough treatment when loaded (if you drop one the right way, shells will spew.)

The mags cannot be carried loaded and loosely, shells will pop making need for Saiga-magpouches mandatory (if one ever had a need to carry loaded mags.)
I've already mentioned that I feel the springbok is not worth the price it commands.
The manufacturing of the springbok was outright terrible to the point that my mag tube wasn't even indexed properly when the cuts were made. Perhaps BAT might have replaced this had I sought a replacement first, we'll never know at this stage of the game.
BTW, I challenge anyone here to find a photo of the Springbok system on the BAT website. If found, please post link here. Why would BAT not display/explain this feature on their site?
That's all I'll say about that. Make your own call on that option when placing your order.
CONCLUSION:
The gun as it is, is a great range toy.
The shooter will not experience any problems sitting at a bench (or standing) and blasting away. If this is all you do, then you will enjoy this gun.
Oh, and it does look Fantastic! That is the reason I bought it afterall. ### appeal does indeed sell.
I have some ideas for improvements, but there is no point in my mentioning them here, or ever.
If you want a shotgun for protection of any kind, it is my non-professional opinion that a traditional tube fed shotgun be used instead.
Feel free to disagree with me, but I paid the big money so I get to give my opinion on the product that I bought.
As I said in my earlier post I was willing to see this thing to the end... but it's clear this is it.
Cheers~
