No. It's logical to have a rifle that has parts interchangeability. If that LWRC is an IC-DI model, that's a good buy. The ambi lower is (I think) the best out there, fit and finish is top notch, and their enhanced bcg is a work of art.

Only issue with that is LWRC is fairly proprietary. Especially in regards to the upper. I only own their lowers now

The good news with KAC is they’ll last a really long time comparing to other ones out there. They’re supposed to last over the 20k ranges so I don’t think you’ll be wearing it out.
With that said you can always just buy an upper and use your KAC lowers to swap them as you want. |

The parts on your KAC rifle that are likely to ware/break or be lost in normal use are commonly available. Just keep some spare parts on-hand.

Isnt the proprietary part of kac mostly down to bolt and barrel?

That’s not dumb at all. SR-15s have proprietary parts and tools. Might not be a bad idea to add a 6920 and/or LWRC DI gun to your stable

Quoted: I have 2 KAC ARs (my only ones). Am I dumb for wanting one that doesn't have proprietary parts as a "just in case rifle?" I have a way to get an LWRC DI gun for 1300 bnib. If you outlive your LWRC, you will have plenty of spare rifles. |

The BCG, barrel, and gas system are all standard milspec components in the LWRC right?

The biggest reasons why the standard DI AR is a good rifle to have to me is parts and how easy it is to maintenance.
I love my e3 stuff along with other non AR stuff but it's definitely not a dumb idea along with spare parts. |

I have an extra BCG for the knights guns, but the barrels/gas system are much harder to source. Not to mention, the tools to install the proprietary parts are difficult to find.

I have the following breakdown:
DD, LMT, KAC, Larue, PWS and ADM KAC, LMT, PWS and Larue has its own proprietary issues....DD and ADM are common. With LMT it is the barrel (MRP) and barrel locking systems. I have a spare barrel and locking screws. Two of the LMTs are pistons and I have spare op rods and one spare BC KAC, I have two sapre BCGs for the 556 and a spare bolt bolt for the 762 Larue, I think I can get away with some of the commmon sapres I have PWS, no spares for it, trying to buy some but OOS The others, I have a lot of spares includung BCGs |

The BCG is not proprietary so that’s kind of a mute point. I’d keep their tools and springs and detents. It’s very unlikely that the gas system will fail in any way. Edit. I forgot about the e3 bolt and extension and the cam pin. I guess you would need a bolt and cam pin however the carrier is normal. |

I usually tried to stick to this line of thinking and only because of the ammo prices have I decided to direct my extra funds towards other stuff. With this said I'm so used to being prepared with mags, ammo, and extra parts that my new stuff seems naked without having tons of mags and spare parts. |

I would suggest going with a Colt 6920. If you are wanting non proprietary parts what you are really seeking is long term reliability and service life. In my opinion Colt is the top choice in that department and I would not look anywhere else.

Oh I’ll add that you’ll only need a spare complete upper to be gtg since the KAC will take any milspec receiver.
Buy a colt conversion kit and don’t look back. |

OK I am reading this and I admit I was out of the game for a while. When did KAC become so propriety, are we talking about the whole E3 bolt etc. or something more? I have 2 KAC rifles that I have put together as well, one is from the 90s and one is recent. I guess I should google but I would hope someone could give me a quick understanding of when they made the change.

Quote HistoryQuoted: What’s proprietary Upper, rail(both how it mounts to upper and how you attach stuff unless you get the mlok), barrel nut, barrel nut wrench,, barrel indexing pin, bolt carrier is one piece design, and then obviously the ambi bolt catch/release. Some of the other parts are enhanced by them like left side ambi mag release, safety, etc, but can be replaced with any milspec part. |

As far as I know, LWRC rifles come with a proprietary carrier, but will also accept milspec bcgs. And I’m not dumb enough to get a gun with a proprietary mounting system haha |

I was even ready to get the barrel nut wrench myself until I was made aware that not every milspec barrel can work as a replacement in their uppers and that they would only mount one of their own barrels should you shoot one out. That just didn't sit right with me so I dumped them. |

Get the lwrc if you want it but I'd consider them closer to proprietary similar to a kac rather than just getting something like a 6920 or DD just to have a normal AR.
You have a kac and a backup so chances are you will be good to go for a long time before bcg's and barrel swaps so getting what you want over need is fine here. Just my .02 |

I get the urge to not want to have a rifle with proprietary parts. Buddy of mine just bought the LWRC DI gun as well and it is a really nice rifle. While the rail to upper interface is rock solid, it bugged me that it was proprietary and you will be forever stuck with that rail. May not seem like a big deal now but I have at least one gun in the safe that I built over a decade ago that has had numerous rail changes. Then there is the ambi lower. Someone else said it can take milspec components if you needed to swap them out. I could see that with the mag release and safety but not sure how that would work with the bolt release. At that price, however, I would pick it up.

Nope, super smart.
It’s the only reason I don’t have a KAC. I have a SCAR16 that used to be my “main rifle”. It’s been through some classes, and has about 5,000 rds through it. I love it. Buuuuut no one else runs one as a primary. So I got a DD MK18. Still absolutely love the scar. Best suppressor host ever. But now my MK18 has taken the throne. |
