If anyone is interested...
Optics Planet has had EVERYTHING I've wanted as far as PCC parts. If you're looking for hard to find parts, look there... |

Quote HistoryQuoted: If anyone is interested... Optics Planet has had EVERYTHING I've wanted as far as PCC parts. If you're looking for hard to find parts, look there... Problem is that they seem to have a hard time distributing said parts of late. Although recently I was surprised that they actually shipped my order within the proposed time frame. I wasn't in a hurry as I can't find an upper anywhere, but they finally got the handguard in and I thought what the hell, if it takes a month or two sobeit. Was in my hand in a week or so. |

Just received a bunch of PSA scorpion mags so hopefully I can get my hands on one of these to replace my NFA glock mag lower.

I'm having an issue with my LRBHO. I put a standard ar bolt catch assembly on it, but the magazine isn't strong enough to push it up. I tried not putting one in it, but every time I fired it, the bolt catch would engage and the bolt would stay back. Anyone have guidance?

That seems to be a common problem. What I did and recommend everyone do is to trim the BHO spring down. I cut off about 1/3 of the spring, it still keeps the BHO down but makes it activate much more reliably. I think I posted all my reliability tweaks in the original post.

Well I ordered and received their last 3 lowers, they gave me a discount on one since it was their display. Got one off being cerakoted and will post pics when I have it back and assembled.
Used parts from my nfa c9 glock lower build with 5.5 barrel and Odin works handguard. |

Anyone find a bcg that works with this? Don't want to grind down the feed ramps if I don't have to, the bcg I had in my glock mag build definitely can't clear the feed lips.

The New Frontier Amory lower is intriguing me more and more. I just wonder if these can be made to work with the RDB BCG. Anybody know? I was going to SBR this Aero lower that I have but now I am thinking about getting one of these lowers and SBR'ing too if it can be made to work with it. I've got an MP5SD handguard cover on the way to complete this build once I have the lower SBR'd and a CMMG RDB BCG (I have everything else already). Yes I know I need to widen the ejection port.   |

Did anyone have to remove material from their ejector? It appears by be making contact with my bcg and not allowing me to mate the upper and lower. Compared to my NFA glock lower, the ejector is a bit further back on the lower.
EDIT; removed some material off the back top area of the ejector, it can not clear a bolt that doesn't have the cut out for an ejector that far back. |

I completely removed the bho spring for now and it works fine when dry cycling the bolt with a mags in. I will shorten it and try re installing it to see how it goes.

I trimmed about 1/3 off my spring and it has worked fine. Don't use it with the detent spring removed, the BHO may bounce up into the path of the carrier and cause malfunctions.

Just built a full NFA build no CMMG upper parts in a 4" pistol and I love how small and awesome this turned out. I am glad the others did the work for me to know that the spring needed to be cut for the BHO. The looks of the Scorpion mags in an AR style is just what I wanted. I have a Scorpion also so it just made sense. Did the 4" barrel as it was the only one in-stock and I am so glad I did. It is so small and compact, perfect.

They just put another batch up for sale on Monday after another very long wait. I bought 2 more. They've since sold out. Get on their mailing list for each item you want, and check it every day. As soon as you get notification, order without delay. I took me nearly a year before COVID to collect all my parts to build my first C5. I've been waiting for about a year for C5 stripped lowers to come back in stock. |

I like your build but I am having trouble with mine almost the same exact parts. My lower and upper are the same as yours but my Bolt catch doesn't seem to be right. It always locks the bolt back with no magazine even in it with the CMMG RDB bolt. It seems like my bolt catch is pushed hard against the outside of the upper and has absolutely no further wiggle room causing the LRBHO to actuate after every cycle. I am left with two options: 1:have the upper milled around the area of the bolt catch2 or try a different catch. I was just hoping you could give me some information on the type you bought and used that seems to work as CMMG's LRBHO does not.

I have switched to a Battle Arms enhanced bolt catch (about $15), which has the top actuator tab bent out slightly so there's more clearance. You could try getting one and see if it solves the issue. |

Hey thanks for getting back to me! I actually took it out and sanded a bit off of the back of the bolt catch and now it functions with no further issues! Can't wait to try it out. I don't know how to attach an image of the finished project or I would makes me have to put in a URL. Thanks for the great write up and I enjoyed the build.

I hate to say it, but even in its stock form (non-CMMG), it has less recoil than my 7" Scorpion. My follow up shots are quicker and the groups ever so slightly tighter. Totally impressed with this tiny new addition. Need to troubleshoot why PSA mags are having feeding issues, but I have Manticore and CZ mags enough to still be happy with the S-9. Fun build and is it so tiny with the Strike Industries PDW brace.

I finally got back to building my NFA S-9, currently it is a pistol but I will do paperwork to sbr it this weekend. I haven't seen anyone that has sbr'd an S-9 lower so I am assuming that it won't be listed in the model drop down and will take several months to get it back?

So thinking about building one of these with a standard blowback bolt - which blowback bolt works with this S-9 lower and C-5 upper combo? NF says you need their C-5 upper for this to clear the feed ramp, but have not bolt suggestions? Help!
Thanks |

The C5 upper is needed because it has clearance cuts for the wider Scorpion mags. This doesn't affect the bolt, any Glock-cut bolt should function fine.

One other question - The AR-CZs seem to be heavier than the Glock types. The NFA web sight shows a pound of weight for the bare receiver - True? I have the PSA AR-V model and it is heavier than all my Glock types. Want a light weight build.

Edit: Reading back helps, looks like HK_DUDE's runs on CZ's and the PSA AK mags. |

Well once again I jumped into another NFA fancy mag build and once again already hitting problems.
From NFA C-5 MP5 build I pulled the NFA C-5 Upper that ran fine once I bought $100 mags. First problem I ran into is the BCG hit on the back of the ejector just barely, but enough where I cant push both take down pins in unless I slightly pull back on the charging handle. Then they both pop in, but the BCG does not look to hit the barrel. Thought the BCG was NFA, but looking at it I do not think that is the case. Edit: I guess either shave the back of the ejector or dish out another $150 for a NFA BCG   Attached File Attached File Attached File Attached FileSecond problem, BCG removed on upper and my mags will not lock in, upper removed they do. Looks like the a barley hitting the upper, even though it has the cut outs. Edit: Did a little rounding on one and it will lock in.  Attached File Attached FileThird problem is it’s so damn sexy that now I really, really want it to run. |

Quote HistoryQuoted: When I close my upper and lower it is hard to push together enough for the pins to slide in. It is doable, but not right. It appears that the ejector is acting as a fulcrum as it is a little high. I will adjust slightly by removing a small amount from the top of it, as it cannot be adjusted lower by design. Exactly what mine is doing, what BCG are you running and did shaving the ejector work? |
