xamoel Posted February 26, 2010 Share Posted February 26, 2010 hey guys, finally the GG&G release button for my M4 has arrived. no sharp edges at all, feels great, looks great. no i just need to get it installed, and the only problem i have (till now), i don't know which hex screw i shall use. i tried 2mm and 2.5mm, the 2.5 is a tiny bit to large, the 2mm is too small. nothing is said in the instructions, so it's up to you to tell me what i need Quote Link to comment Share on other sites More sharing options...
