Meprolight HK MP5, G3, 33, PTR, SP5 Night Sight Set

Just pinch the pin, replace the front sight and screw out and put everything in will be fine! It perfectly fit!! Bright, clear and superb!!! Love it!

Follow the picture description above and it will go easily. I did use a bench vice to hold the SP5K in place as I tapped the front sight pin out of place with a punch and removed the original sight. The kit is complete and installs perfectly. The rear sight is smaller than the front in regards to the illumination at night.

I followed Matt's suggested way and it went flawlessly. These sights are bright, clean, and easy to use in low-light situations, extending the usefulness of your HK to late at night. Plus they look sick.

I initially saturated the original sight blade and roll pin in Break-Free Oil one day prior to install to loosen the original parts on my POF MP5. I then drove the roll pin from the end of the barrel toward the receiver using a 1/8 starter punch and 1/8 punch. The Meprolight then slid into place and the roll pin reinstalled in reverse order. The radioactive tritium in the sight is as bright as I've seen on any number of similar sights. The sight measured exactly center of the front sight hood just as the original.
