Looking to replace an O/S .46 LA. I see that O/S have a .46 AX, an there's a number of offerings from other manufacturers like Fox, GMS, Magnum, Super Tigre, Thunder Tiger, and YS. I just wanted to get some input. Super Tigre also makes a .51 that I might be interested in.

Any recommendation as to what to buy and/or what not to buy?

Thanks!
