Things I liked:very nice weight for a plastic gun, also tough! can handle a good drop or hit no problem! Rear aperature sight rotates like the real H&K peep sights for different size openings.This gun is VERY accurate at close range... i mean ON POINT!! Mag release is just like the real MP5(the lever actuates a side release slot).The spring option is nice and makes for a functioning charge handle (what MP5 would be complete without being able to raise the barrel and slam the charge handle after putting in a mag?). Great Heckler & Koch branding. Awesome gun for CQB. Hits hard at close range, isnt bad at mid range either (50yards or less). I considered the P30 to be a "freebee" when buying this, wasnt expecting much. Actually its a nice little springer for that last sec quick draw one shot moment. Things I would have changed:Make the selector switch ambidexterous, I use both sides depending on my position. Print the H&K branding in white like the real gun. minor gripes What others should know:An excellent CQB gun just like the real MP5A. 50 yards in, theyre yours! Nice little P30 springer to boot! Buy it!!
