AR15 lower ATRS, CADEX or DLASk OR other?

This is the first time I've seen any mention that a MIL Spec LPK cannot be used and parts need to be modified in order to fit your lower.

I feel I should mention that I have seen Rick reiterate this same thing about 10 times now… in just about every thread that it comes up in. Should probably put it on the site, but yeah, he is starting to sound like a broken record.

Also, I believe the lower has captured springs, which requires cutting the springs… really it should be pretty simple, but as he said people have tried and failed. Capturing the springs lets you change gips and stocks easier, it is a nice upgrade, but not possible to do without cutting the springs.

I degress… I have a Dlask and a Noveske Gen 2… the finish on the Dlask is quite nice, the nicest I have, I have no complaints as per fit and finish, although the engravings could be a little nicer. The Noveske has an integrated trigger guard and I giant flare on the mag well, but the finish is a little light for my liking, yet to test the fit but I am sure it is above par…

I have shot a bolt action rifle built by ATRS and ever since I've been thinking of purchasing a Gen 4 lower.
I couldn't figure out why ATRS wouldn't sell the stripped lower.

Shouldn't this be mentioned somewhere on your site so people are aware that if something goes wrong in the future they cannot just replace X,Y, or Z with MIL Spec Parts?
Wouldn't a small writeup of the modifications or a Youtube video be of use to your clientele?
Couldn't the lower be made in a way that it would accept a standard MIL Spec LPK?

On our website we do mention that several springs are captured. I did not see it as necessary to go into detail that due to this, these same springs would need to be shortened. Our ambi bolt release is proprietary just like KAC, POF and every other maker who offers this feature. No-one seems to bug them over this.
We also list our lowers being available WITH Milspec LPK installed so sorry I don't see how 1 would figure that these LPKs can not be used.
Should a spring fail in the future you simply need to shorten said springs replacement spring 1 coil at a time until it works.

I think some are reading waaaay more into this that is needed. The fact are. Our lowers ARE higher quality than most, they DO have some features not found on others, but Milspec parts which are the lowest commonality will work just fine in them. SOME of the springs need to be altered or the capture screws will have no room to fit, absolute worst case delete the capture screws and run milspec stuff. Personally I rather like being able to take off my grip or buffer tube and not have stuff go flying. The biggest fact we have found is not everyone is capable of what we consider pretty simple assembly, so in order to solve this problem we opted to not only assemble but test for function our lowers at no cost to our clients. I can not think of any other manufacturer who offers this value added service on their lowers.
 
The Hera stuff is pretty slick. But seriously, 425$ for a stripped upper? It's nice but man, that's expensive. Picked up the Hera MPSS for my ATR and it's really nice. Anywho, the Hera stuff is also top notch but prepare to bend over for it.
 
Little Umbrella Corp, Cadex and KAC.

Cadex ftw, great fit and finish, good for large hands as well, mag-well is beveled for easier tac reloads, highly recommended.
Ask that guy^ I bought it from him.

The Herra HLS lowers were cheaper than any of the billet lowers suggested so far. Plus they are the only ambi ones that also have the well for the left side mag release. ATR has the same bolt release but not the mag release well. All the billet ones have built in trigger guards and flared magwells. Perfect finish, 7075 T6 billet, full ambi and esthetically they are a very nice clean looking lower.

I looked at all of them before making my choice. The only reason you're not hearing much about them is because I have the first two in Canada. They aren't cheap but for the high end billet lower ambi market they are the least expensive. Plus one of the nicest.

The only other lower I would consider is the KAC lower. If LMT marked without the QR points at the back and a cheaper price, Id have a few of them. KAC holds one of the best designs for the modern lower. Put an ADCOR or LMT MRP upper with SS barrel and you have the ultimate AR. But.... Price, cheesy markings and finish that doesn't match the ADCOR. So Herra HLS was my choice. Although by the time you're done putting in all the best parts you're only 100-200 of the price of the KAC. But you get exactly what you want. Plus managing to snag the first few was kind of neat. It's differnt.

Sorry, I have no experience with their lowers, and was talking about the upper when I was quoting price above.

As far as the "well for left side mag release", what does this mean? Different than a Norgon mag release?

The Norgon mag release is just the mechanical part that let's you use the left side to release the mag. On a regular lower it's exposed. There is no protection from accidentally activating it. Every lower has a well and fence protecting the regular mag release. The true full ambi lowers also have this protective fence on the left side as they were designed from the get go to be ambi.

There's tons of pictures on here. I'm pretty sure I posted this with pictures a few months ago. Sorry not bothering with an iPhone to repost that. It's much easier for someone to just use the search feature.

Ah yes, I see what you're saying. Personally I've never accidentally hit the left side mag release and those larger grooves don't really appeal to me. To each his own I guess.

If the Norgon release was installed on that HLS lower it would look right. It's not a huge deal but it does look decent when the ambi parts are installed. It also helps with indexing and location when doing manipulations. If nothing else it matches the mag release fence on the right side of the receiver. You'll note every lower has this on the regular mag release.

That's one of the things I like about the KAC lowers, all the ambi parts match in look and design to the regular. For example the ambi controls are paddles like the regular bolt release.

The Hera HLS lower is the Magpul design. The one that was rare and going for 3K in the US. It's the same design just different markings.

You won't go wrong with any of the high end stuff. It just comes down to preferred features and cost along with personal preference.

If you get a chance I'd like to see yours with the Norgon on it if you have one. I've been looking at their lowers all day and it's kind of growing on me. It's a different look. I currently only have a fancy billet lower so my next build is going to be a more traditional forged milspec upper and lower set, but that might make a nice 3rd build... :D
 
I'm waiting for a parts kit. They have one in and hopefully the second one should arrive soon. I ordered them a few months before the crazyness in the US do hopefully it will be good. I do have the Norgon releases just waiting for the LPK sets.
