It's nickel teflon what more do you need?
by Heed -
I had to purchase this to go with my np3 upper, but even if I hadn't purchased that upper i'd have bought one. It's the only bcg i've seen that actually cares enough to install a sprinco 5 coil and OCKS screws as every company should. I put a sprinco ejector spring in it as well. This feels slicker than nickel boron or dlc. One of the main reasons I had to try it was because of the difference in the feel of a Schmid nickel teflon mil spec trigger group vs a nickel boron.
<br>Hopefully this was a better choice than hard chrome.
Quality under the Radar

If you are not familiar with Sionics, do your homework! They are an OEM for over 70 law enforcement agencies. They hand build every rifle, and I have been really impressed with their work over the years. I've had a Sionics upper with this NP3 BCG for several years now, and out of all that I own and run, it's the one I rely on the most. I run suppressed, unsuppressed, crap ammo, good ammo, classes, etc. It has been flawless and easy to clean. I prefer this particular BCG even for my budget builds. You can skimp on a quality budget lower from someone like Aero on a sale, but use high-end internals such as this to get reliability.
