    C-5 80% lower

    Posted by Luke Sparrow on 26th Dec 2023

    NFA quality and style is second to none. A perfect matchup to a C-5 upper and it came together without a flaw. Fits KCI gen 2 mags perfect. I think it’s the best MP5 mag lower on the market.

    Really nice pieces, not too difficult to finish if you have the right tools and take your time. Wish they still sold the jig to do the AR10 lowers but I don’t see jigs on their website any more.

    80% lower

    Posted by Stephen H. on 9th Sep 2023

    I have bought finished and even a couple blem lowers from NFA but I wanted a blank lower to try engraving myself. This seemed like the easiest way to get just one plain lower. I have bought raw lowers from them also and they arrive grit blasted, pretty much ready for Cerakote. The 80% lowers are smooth and need to be grit blasted after you mill them out before you apply a finish. I like the style of their Gen 2 lowers, they are unique with the finger rest cut and the lightening cuts in the sides. Milling the pocket for the trigger wasn’t too difficult, I used their 80% jig to hold it in an old manual mill I have. I went really slow so I wouldn’t make a mistake and I spent nearly five hours start to finish. I used a drop in trigger to check the fit and function, everything worked like it should. Went ahead and assembled it before painting so I could try it at the range. Mags are a little tight, might need to lightly sand polymer mags if you need them to drop free. I might do another one, they are fun to do. Need to pull it back apart and work on the engraving now.

    As always package like Fort Knox, and again as always, I cannot find the blend. Shipping was very fast. I ordered on Friday and have it the following Thursday. I was amazed.

    C5 & c45

    Posted by George B. on 4th Apr 2023

    Bought the C5 & C45 and they seem to be great quality. Machined them and everything went fine. For the C5 stick with metal mags. Tried 2 different brands that were polymer and they are really tight, like you have to yank them out. No drooping out unless modified, not a big deal but also not necessary with steel mags.
