Its bad. the outer barrel doesnt aline perfectly makes a slight shift to the right. Makes your bb land meters away (to the right) from where you aimed
I have resaved my HK416C yesterday and I am very happy with it. It has een amazing kick to it and sounds really good. Shoots great and coms with a stiffer spring. Resaved the package with in 8 days.
Not like 5KU, this is genuine one-piece barrel, fit for E&C very well
Product arrived in a timely manner and was in perfect condition, will fit GBB, Airsoft and real mil spec ar15, fits perfectly no mods needed, great prices and even better deals , thank you 6mm I will return to shop and I told everybody I know to check out your store just be mindful of shipping time.
