Noveske Gen 4 Lower VS. Radian Weapons A-DAC Ambidextrous Billet AR-15 Lower

[Dutch110]

I think the LWRCi has one of the best ambi lowers on the market but rarely get mentioned in those discussions.

That being said, while I love my LWRCi, I find the lower doesn't offer me anything that my home built lowers using FCD parts don't. I guess there is an argument to be made when shooting offhand that the lack of a bolt catch/release on the opposite side is a detriment. But slingshotting the charging handle is a thing too.

I think the only shop that is doing full Ambi right is Sig on the spear lowers - up to lock down to drop the bolt. I don't want a paddle. I much prefer the way Knights does it with the ability to just drop the bolt and Ambi magazine release. So easy to drop the bolt in prone. But I am not left handed.

The Radian AX556, ADM UIC, and MVB all don't use paddles, with the UIC predating the SIG by years and using the same manual of arms (as do the ambi H&K lowers). The Radian and MVB both have the bolt release lever in a similar spot as the KAC.

Yes, I get that.

I don't own one single "cool" lower. "cool" by internet h0m0 standards that is.

I'd love to get a BCM lower and one of those Colt US Gov property lowers. The ambi gay stuff isn't my thing though.

I bought a stripped BCM lower that was a special run, I was told they are not normally sold as stripped lowers.
I bought a complete BCM upper and the now rifle is the loosest most rattling (between upper and lower) I have ever seen.

The accuracy is horrible also, to give you an idea I also built an aero upper and lower using Seekins lower parts and Aero upper parts and this one is way more accurate and the fit between upper an lower is correct (read: snug well fitting).

I'm hoping to run across someone with a BCM lower that came from BCM that way to put my upper onto see it it fits better.
It fits other lowers Ok so I believe the lower is the issue.

Every BCM lower I’ve tried has had a loose sloppy fit with the upper receiver, to include BCM upper receivers. This isn’t necessarily a bad thing, as they are machined to mil spec. Every assigned weapon I’ve been issued by Uncle Sam (both Colt, and FN) has had a similar loose fit between receivers. The lack of accuracy has more to do with the barrel, or your skill set as a shooter. I used a BCM upper receiver with a Colt SOCOM barrel on one of my previous builds, and it was as accurate as any other SOCOM barreled upper I’ve used.

Ok, I'm not sure the issue with mine then.
If I can get good groups with one rifle but not another I just figured it was the equipment.

Thank you for the post, it's good info.

What make of barrel is on the one you have issue with? Upper to lower fit doesn't really have much to do with accuracy, when you tension up the weapon before you fire, you are eliminating the play. Its not like you are shaking it one handed while firing. Only MarkM shoots that way!!

The above is a copy paste from the email order confirmation from BCM hopefully it is readable.

Can you define horrible accuracy?
