New Frontier Armory C9

I am looking for a Glock pattern AR pistol and am considering the New Frontier C9

https://www.newfrontierarmory.com/shop/c-9-pistol/

I haven’t been able to find much info about their complete uppers or complete pistols.

Price seems great. It is considerably cheaper than QC 10, Angstadt. How does it compare?

I can only speak to my limited use of the MP5 mag lower of theirs I built. Build quality is decent enough. The extractor on mine is good but a friends came loose on the first range session. Locked his bcg up pretty good. Simple enough to fix but couldn’t have been tightened to spec from the off. I used a Colt LPK with an ALG QMS. Had to switch to a Daniel Defense trigger to solve an issue. Not sure what that was about as the trigger was fine in a 223 AR.

I used their upper and mlok rail with a BA barrel and Spinta BCG. The upper is nice and the rail pretty inexpensive. It does the job for me with no frills and was an easy install. My friend went with the side charging upper. I shot it and it is pretty handy but feels like something that could fail. Or maybe I am biased to a regular charging handle?

As far as the Glock lowers, they are pretty popular locally as the store is here. Everyone I have come across speaks well of them. Hope this helps a little.

Thanks for the info. I was considering a Stern defense Magwell block but will probably give this a try. I prefer it dedicated Glock lower.

I can speak about New Frontier Armory barrels………….They are of good quality, work fine and with that said I would think their other products are decent as well…………I do have a QC10 Glock lower and have used it with three different uppers………never a failure to feed or eject…….their last round bolt hold open sucks………I took the LRBHO parts off and put them away in the parts bin……….The QC10 lower is off good quality, they are pricey compared to the others out there…………If you want a decent BCG, buy FM products, they are like 100 dollars at Brownells and they are awesome……….no issues whatsoever. I have Colt style and Glock style from them………….Yankee hill Machine is making a reasonabley priced Glock lower…everything I ever have purchased from them is top quality.

Upon further review I’m getting a Foxtrot Mike upper/lower

Should be GTG………I have two foxtrot mike Bolt carrier groups in 9mm ……I was told by FM products the Colt bolt will work with Glock. The Glock bolt will not work with Colt………I paid less for the two BCG’s than I did for one from another company three years ago………lol

I would get the FM products Colt bolt…it works with both Glock and Colt………their Glock bolt only works with Glock………

Hi there, curious as to why you decided on Foxtrot Mike as opposed to New Frontier? Please do share.

Because I found this:

It runs great. I am very happy with it
