Worth every penny - JP Enterprises VMOS AR Bolt Carrier

This, along with the JP SC buffer and an adjustable gas block, lets you get the most out of your AR platform weapon. In the case of my AR10, function is glass smooth, recoil is easy to anticipate and control, and the weight it does add only helps me balance my rifle. The price is nothing to scoff at but I’d say it’s a considerable upgrade and definitely worth it.
