Revised below (in descending order, according to length);Hi All,
1) As I understand it, the series goes something like this (in descending order, according to length):
a) 550 / Stgw. 90 (full rifle: non-restricted)
b) 551 LB SWAT -- CQB (restricted)
c) 551 SWAT -- carbine (restricted)
d) 552 SWAT -- ??? (restricted)
Is this correct? I'm confused as to the difference between QCB/Carbine etc.
a) 550 Sniper - marksman length rifle - has a 25.59" barrel and full length forestock. Standard with flattop and other fancy goodies such as adjustable stock.
b) 550 - full length rifle - has a 20.79" barrel and full length forestock. Standard with diopter sights, or optional flattop.
c) 551 LB - carbine length rifle - has a 17.9" barrel and mid length forestock, allowing for bayonet attachment. Standard with diopter sights, or optional flattop.
d) 551 - carbine length rifle - has a 14.3" barrel and mid length forestock. Standard with diopter sights, or optional flattop.
e) 552/553 LB - CQB / carbine length rifle - has a 14.3" carbine barrel and short length forestock. Standard with diopter sights, or optional flattop.
f) 552 - CQB length rifle - has an 8.9" barrel and short length forestock. Standard with diopter sights, or optional flattop. This is obsoleted by the 553.
g) 553 - CQB length rifle - same as above but with revised gas system as found in other lengths, used to be different in the 552.
*notes: SWAT designation refers to accessories & finish. Models designated 55x-1 have 1:10 twist, while 55x-2 have 1:7.
As others have mentioned, there is a functional difference between the SG55x series and the SAN rifles available in Canada.
Cosmetically they are identical, although SG/SAN equivalents are not currently available in some configurations.
Buy them all! I dare you
