Love this bolt carrier. In conjunction with a jp silent capture spring, this thing runs like a top; you have to remove the weight in the BCG to run it with the jp buffer assembly. But the weight of the buffer assembly makes up for the removal of the BCG weight. You won’t be sorry, this thing is awesome, especially for the price. It works with the jp spring and it works well!

I ordered this BCG on a Friday and got it the following Thursday. Optics planet has THE quickest shipping and best prices!! As far as the stern NiB BCG goes this thing is sweet @$$ sweet! Very easy to clean extracts reliably every time doesn't nose dive rounds. Ive put over 450 rounds thruand nota single issue! I have it matched up with the trybe "10.5 barrel and its a perfect pair up! The bolt actually has allen screws that hold in the weight and the extractor. I haven't ran it with the echo trigger just only a mil spec and its just lovely!!! I haven't seen many 9mm bcg's in the NiB coating but this stern bcg is soo worth the $!! Stern is high quality for the more poor people of the world! I appreciate the quality and without breaking me!!!! Im planning on pairing it up with a JP barrel next but would NEVER change out the stern bcg!! Thanks again to Optics Planet for the quick shipping and BEST PRICES!!! And thank stern defense for helping out the poor man!!!

This product works 100% with my echo trigger and my sylvan arms folding stock adapter. The NiB finish is a must for a dirty suppressed 9mm blowback. I couldn't recommend this product enough. I wasted money on other 9mm carriers before getting this one, don't make the mistake I made and just buy this one. Most 9mm carriers have to narrow of a slot to fit the echo trigger.

So i am new to the AR-9 platform, but had read good things about Stern Defense so i figured i would give them a try. I am happy to report that the BCG has functioned flawlessly through its first couple hundred rounds. I have it paired with and Aero EPC 9 upper, as well as the Stern Defense Mag AD9. Feeds rounds from both standard glock OEM mags as well as the ETS mags i have tried so far. If you are on the fence about what BCG to install in your AR-9 project, don't hesitate to go with Stern. I would highly recommend based on my experiences thus far.

The bolt I had been using functioned but showed signs of deformation along the bottom as a result of hammer "bounce". This indicates problems elsewhere, but the fact that old bolt was soft enough to record these impacts indicates the bolt was too soft. The Stern Defense version is a daylight/dark difference. The machining and surface finish is superb. Function is 100%.
