The HK33SG1

HK33 Sniper Variant

Cal. 5.56 x 45 NATO

The 33SG1 is a sniper enhanced variant of the HK33 rifle.  The barrels are hand picked for accuracy, and the standard buttstock has a slightly adjustable cheekpiece, as is the case with the G3SG1.   The only difference in these two rifles is the caliber.

The HK33SG/1 The SG stands for  Scharfschützengewehr or sharp-shooting rifle.  Actual interpretation would be "marksman's rifle." It also has the set trigger group like its big brother, the G3SG/1.

 

Close up of the G3SG/1 Set trigger group.  This is identical to the 33SG/1 trigger group, and could be exchanged between the two rifles simply by swapping the ejector. The button behind the trigger is used to "set" the trigger when in semi auto mode, and allows the gun to then be fired with a trigger pull of about one lb.
