YEs! SIG 551 uses AK type mag release ! its all in the training!
infact it gives a positive lock on this kind of mag release ...
thus we don;t have the problem like our M16 where it drops or did
not sit properly! which is why we need a tap after each mag
insert.
Yes it is loosly AK design ( thus the reliability) but the fit ,
craftsman and tolerance makes the accuracy!
The overall quality and make of the rifle is phenominal! non
assualt rifle I have seeen is so well made ... its made like a
swiss watch! .. its sight system is superiroor to our M16, accuracy
is awesome....., reliability ( piston base) is very good, mag
design is much more superior, you can clip them together, don;t jam
easily like out cheaply made M16 mags!, sturdy and feel and very
rugged! winter trigger design that ease usage in winter
conditions!, it is pretty IMHO
the only downside of the SIG is , its EXPENSIVE, does not have
adjustable buttstock length to ease body armour and other SBO
device , a little heavier than our M4. Ergonomics is not as good as
the M4.
I can go on! but you get what I mean! overall, it is all rounder
type Assualt rifle.
maybe a new HK made M416 or some piston based M4 might change my
mind in future!
