Talking about being spongy the PE90 trigger is consistently and precisely sucky. I don't know how people like a heavy spring loaded first stage with a light break so much. I am not at all in love with the PE90 trigger at all. I much prefer a good clean single stage or two stage AR trigger (or american style trigger).
The SG is a swiss AK - down to the bolt. SIG made no bone about it they were switzerlanding the AK and they did an excellent job, in addition to adding 2lbs to a light assault rifle to make it a 9lb target style recreational combat rifle that shoots 224 bullets on family days....the swiss arms is a nice rifle but it is definitely not worth the mystical reputation it has over all other. I own two myself but I understand and realize what they are!
Still, it is way better than the plastic thumbhole abomination that HK markets.
I found it interesting that people are so obssessed with the swiss 300m belly shooting on a bipod. How about the USMC that shoots M16A2 at 500m KD in basic with no articifical support.....no one sings praise of the M16.
