NBS 9MM Colt Magazine Magwell Adapter for AR-15
Easy install, no modification needed, worked perfectly, no problems. accepted ASC mag no problem, no jams, ran 150 rounds.
USGreat product
Makes both my Stribog run like a sewing machine, no failures in over 500 rounds.
USWorks Great!
I had been using an EndoMag adapter up until this point. I had been experiencing problems with the bolt face barely catching the next round and the last round hold open lever was barely catching. I wanted something more dependable, so I bought the NBS magwell adapter. I installed it into my Anderson lower. What everyone says about the fit into an Anderson is not lying. I had to file the front and rear of the adapter before it even began to fit into the lower. After greasing the housing and driving the adapter home with a rubber hammer, it was finally in. The Duramag magazine that I had also purchased went right in. I then loaded some ***** rounds to check loading and ejecting. Was pleasantly surprised to see that the bolt face now contacts a round with room to spare. The LRHO also engages with room to spare. Fed and ejected the ***** rounds without any problems. Can't wait to try it with live rounds!
USNBS magwell adapter
Well designed and installation was simple. A nice tight fit. Have run 150 rounds through it without a failure to feed, jamming, or stove piping. Have noticed how it takes a good bump to fix mag when bolt is closed, so have been inserting with bolt open, especially since the bolt always stays open after last round. Running steel duramags in Colt pattern, flawless..
USHave not used it yet
I guess I get a discount code if I write a review but I will not be using this any time soon so all I can say is that it was packed well, was reasonably priced and arrived in a timely manner
