The SA80 in all truthfullness is a PIECE OF CRAP for many reasons:
1. The cocking handle gets in the way of the ejection port which is prone to breaking it off
2. crappy trigger pull
3. too many (poorly made) plastic parts
4. hand guards pop off for no reason
5. firing pin prone to breaking
6. weapon is quite small, but very heavy, and extremely heavy in the butt (muzzle climb problems)
7. jams at the drop of a hat
Overall, for target shooting alone, not a bad weapon and very accurate, but the moment you take it into the field, get it wet, get it dirty, or operate in anything other than stellar conditions, it can fail miserably. The sight system is good though, which is it‘s only redeeming quality. Give me a C7 or other M16 variant any day over an SA80!
***NOTE*** Based on my own observations, and experiences of others who have had a lot of time with both weapons.
