Other Specifications and Features of the S-9 Stripped AR-9 Lower Receiver:

  • Machined from 7075-T6 aircraft grade billet aluminum
  • Matte black hard-coat anodized per Mil 8625 Type 3 Class 2
  • Precision machined magazine well with beveled feed lip for easy mag swaps
  • Machined and engraved to be compatible with 45 and 60 degree short throw fire control selectors such as the BAD_ASS ST 45 Lever
  • Compatible with most standard AR-15 components and aftermarket parts
  • Take down pin spring and detent hole is threaded for a 6-32 set screw for easy capturing (hardware included)
  • Upper tension screw behind grip screw (threaded hole with hardware included) to adjust any “slop” out of vertical fit between upper and lower
  • Ambidextrous trigger finger rests with grooves (above and below mag release / mag catch)
  • Threaded bolt catch pin (Threaded hole and hardware)
  • Integrated large opening “winter” trigger guard

  • Save money by building your own AR-9 rifle from the ground up exactly the way you want it configured and shoot for less!

 

  • To allow clearance for the feed ramp, you must use our New Frontier Armory C5UPPER with this lower receiver. Our C5-NRSC upper is NOT compatible. 

 

  • *Due to the force exerted on the BCG with a blow back system, there is a high likelyhood of breaking the bolt catch when activated by the LRBHO feature.  New Frontier Armory is not responsible for sending replacements as this is not a warranty issue.  

 

 

The New Frontier Armory S-9 Stripped Billet AR-9 lower receiver is proudly MADE IN THE USA by hard working American men and women.

    Awesome AR9 lower. I have used every AR9 lower from NFA and I absolutely love the C5 and the S9. Make sure you read the details though, you have to use their correct upper receiver for clearance for the feed ramps and magazines. I am a machinist so I had the capabilities of cutting my own clearance slots in the non reciprocating side charging upper. I think using the MP5 mags in the C5 and the scorpion mags in the S9 are so much better than using pistol mags. Aesthetically I would choose the S9 over the C5, I don’t know if it’s the arc of the magazine but the C5 has a little notch halfway up the magwell and the S9 doesn’t so I think it looks better. I really wish they would offer the S9 in an 80%, I have several AR’s in all sorts of calibers and I like to do as much work myself on my builds as possible. My C5 and S9 are the only lowers I have that I haven’t finished from 80%’s, they just got some C5 80%’s in stock so I plan on ordering one of those and I emailed them and was told they had plans to offer the S9 as an 80% but didn’t know when. I highly recommend the S9 lower.
