oh and 1 more thing...reloading is a problem with the SAR-21...they should make the clip hold 50 instead of 30....so no need to reload as often...though that would make it heavier.
Sorry.... another add on. I don't speak only from my own experiences.... Some of them like getting cuts while cleaning rifle, blurry scopes, loose LADs and night shoot without LAD are some we have talk about. The iron sight is alright for the day, i hit five out of six targets at 200m range but at night, a prometium tip would be a gd idea.
Sar21 need time to improve......
M16 with LAD and Scope fit on,the weight is heavier den SAR21
