Not sure why the link doesn’t take you directly to the lower receivers section so, just use the search feature.

Opens the same page for me, maybe because I’m on mobile? Idk.

If I were to start a fantastic build now, I'd try really hard to snag a Geissele Super Duty Receiver Set tomorrow for $157.

Yep, that's more than an Aero or Anderson, but you're worth it.

Another super solid option is the Sionics Gutless Lower Assembly. I took this route with one, and it's a supremely well machined and finished lower.

If you'd really like a Colt 6900 series, there are options for that as well.

Brownells has the Colt LE6960-CCU upper on sale right now for $515, not including BCG. It should be possible to find a new Colt BCG for around $190. I bought the BCG for mine from Arms Unlimited. In case you don't know, the 6960 was a rifle Colt sold for a while with a mid-length lightweight (but not pencil) profile barrel, shaved FSB gas block under a Centurion Arms 13" M-LOK rail, an ambi safety, and a Magpul SL-S handguard.

In 2017, Brownells was selling complete Colt M4 lower receiver assemblies for $250. It shouldn't be too difficult to track one of these down without paying too much of a markup.

This will give you a close equivalent to the 6960 for a bit over $1,000, which is what basic 6920s now cost.

Thanks much! But I think I do like the concept of me "building" the gun from scratch and picking all the parts (with help from you folks). In that way, I can also give a real nice "big finger" salute to Colt!

If you want to build it from scratch, then go for it. I will be finishing up a 308 lower on Saturday.

Would you like the lower to have any features beyond what's found on a standard forged mil-spec one, like ambidextrous controls, or do you like the appearance of billet lowers? If ambi is important, I'd choose an LMT MARS-L or Radian's ambi offering. They're not inexpensive, but probably less than an SR-15 ambi lower. I've got no experience with billet receivers.

If nothing non-standard is needed, then LMT's Defender, Geissele's Super Duty, or ZEV Technologies lower would be worthy of consideration.

Aero and Anderson make solid lowers, but I personally wouldn't use one in a fantastic build.

Why not? Please explain.


man has suggested really nice “higher end” products you can use, the quality is there for sure. You won’t be disappointed with any of those lowers/uppers.

If you plan on only building one (1) rifle then, go big or go home. Otherwise, I suggest you start off in a more budget friendly build. This way you can learn the ins and outs of building the rifle and if you scratch it along the way, you won’t cry too much damaging that Instagram worthy upper/lower.

Just my $0.02

Well, we are on our way. Two lowers ordered.



1) Anderson Manufacturing - AR-15-A3 AR-15 Stripped Lower receiver


2) Radical Firearms Forged Stripped AR-15 Stripped Lower Receiver (RF-FL).


Plus some spare parts including:


1) Geissele Automatics G2S Two Stage AR-15 Trigger .154"




Expect shipping to my FFL in 5 business days. We'll see. But now I have to look at all the other parts, including the uppers.
