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.
Tout est dans le review title, aucun problème, livraison un peu longue mais normal vu le site d'expédition.
Je recommande ce site

Good price for these only downside is how expensive the shipping is.
