I fancied them due to the adjustability, and was delighted when a kind fellow on here (Briar) invited me to handle his in the flesh (ooerr Missus !), as obviously best to handle before deciding. It felt great, specifically the sculpted grip as it fitted my large hands, but a few people have said the grip is too large for them. This was previously addressed by the Decima versions, but I believe the new range has possibly reduced the dimension of the Hunter and Sporter stocks. The Berserk feels about the same in terms of grip size, but unsure if it is identically dimensioned, but does feel nice.
I'd not say the adjustment mechanisms jump into loads of bits, but would agree perhaps some form of stop to guard against accidental disassembly would be a boost, I have done it once or twice.
Anyway, best to get your hands on one before comitting.
