[kyrin88]

Hi I am trying to find information on this rifle. This guy is selling me an sr-15 m4 upper, but i have no clue about the dam thing. All I understad is that they are a bit rare. What is the twist rate, is it mil spec etc can someone give me some specs. Thanks:confused:

If it is an older gun it might have a pressed on fake flash hider . If it is then it is a pretty standard AR type upper with a M4 RAS . If it is a SR-15 E3 upper it would be more valuable. The SR-15 marked upper rec. do bring a fairly high price by themselves but there is not too much special about it.
