Geissele Trigger for HK416 and HK MR556

Very similar in performance to the SSA trigger, but made specifically for 5.56 platform H&K rifles.

The Geissele MK MR 556 trigger can be used in both the Heckler and Koch HK416 and the MR5456.  The MR-556 trigger has a much heavier pull in the second stage of the trigger than the SSA trigger, but that is somewhat expected in a German gas gun.

Type:      2 Stage
1st Stage Weight:      2.75 to 3.00 lbs.
2nd Stage Weight:      1.50 to 1.75  lbs.
Total Pull Weight:      4.5 lbs., +/- 0.25 lbs
Adjustable:      No
Recommended Use:      Law Enforcement, Target Shooting, Precision Shooting

Note: After installing the MR556 trigger you must cock the hammer in order to engage the safety, unlike the HK trigger system where you can place the selector on Safe with the hammer forward.
