You can dry-fire an AR lower with the upper removed --- as long as you have one of your least important fingers positioned so as to keep the hammer from hitting the reciever; while having another finger on the hammer while you press the trigger.
So I just got off the phone with Paul at NDZ. Great guy and more than stands behind his product. Apparently he reads the forums and tried to join to reply but admin hasn't confirmed him yet. Anyway, he's aware of the problem and thinks it could be a clearance issue that may be occurring (we're talking like tiny measurements). They are addressing it on the ones they're shipping out now and he's hoping that will clear up the problem if anyone else is having it. He also said that they will do whatever they can to bring this product to market, meaning that they're in it for the long haul no matter the fix.
I'm going to send mine back and he will mill a tiny bit of aluminum to clear the contact point. It weighs 8grams just like the bad lever so he doesn't think it's a weight issue.
Lastly, at Paul's request, for those of you who have ran the SBR already, please shoot NDZ an email describing the problem so thy can see what kind of scale the malfunction is happening on. He's a stand up guy and will do right by you.
Hope this helps for anyone else having the issue!

I don't know what company NDZ is. As for SBR --- I'm assuming that you mean short barreled rifle? If that is the case --- you might need to change your buffer; and maybe the buffer spring.

It is a battery assist lever, same concept as the Magpul BAD. The 15-22 lower receiver is physically different than an AR15 lower, and NDZ has made their version of the BAD lever and call it Speed Bolt Release.
If its making contact with the lower anywhere that could do it, make it not fully actuate and fall off the bolt face easer. Gotta make sure the only place it touches is the paddle area, it is good to see them fixing/replacing the defective ones.
well went to the range today and im having the same problem - it rarely locks open and when it does, the smallest movement such as touching the trigger causes it to slam closed. not a huge deal but looks like i will be emailing ndz for some follow-up.
I don't think it should be touching anything when it goes to lock back. That's the problem I bet, it's not fully engaging the bolt face so any little bump or movement could let it slip off.
That was the fun part of making one that worked was figuring out the correct placement of when the arm has to bend to be close to the lower but not so close that when the arm moves it hits.

It shouldn't. Like I said before, out of my mags the only one that had problems was the one with a slightly shorter post on the follower.
That being said I don't have 10 round mags, but the other fella I had test did, and it worked for him.
If the arm is touching anything other than the bolt catch release where it attaches that's going to be a problem. The spring in the mag has to overcome the weight of the added arm, and the spring in the bolt catch release, anything else stopping it is probably too much.

Range report from my gun. My SBR ran 100% flawlessly through ~50 rounds of CCI Blazers and ~10 mag changes. The bolt locked back every time my mags were empty. The bolt also did not accidentally close.
I used one 10rd long mag that came with my gun and two 10rd short mags that I bought off 44mag.
I don't know if it matters but I have a Mass compliant rifle with the JP yellow spring kit installed.

Really??? You are going to modify your stock rifle to make a $36.00 accessory that apparently is not ready for the market yet work? This thread amazed me. Cutting springs and adding shims just to make a tactically cool but non functional accessory work is over the top in my humble opinion. Inadvertent bolt releases…. No bolt stay open….All for an item that lets you keep your finger inside the trigger guard during magazine changes….sounds downright dangerous to me.
I am going out to my garage….if I can make something COOL for my rifle someone here will buy it

I know, right?
Funny thing, I haven't had any problems changing magazines and using the factory bolt release to close the bolt. No last-round hold-open problems, no accidental bolt releases, and I haven't sprained my wrist by using my left hand to hit the bog-standard bolt release that every AR-15 pattern rifle for ~50 years has had.
I must be doing something wrong.

im not sure if you meant to come across so judgmental about the entire thread or just one person's reply. everyone else seems to be just testing theirs out or contacting NDZ for follow-up.

so i guess you have a 100% stock rifle and have never added anything to improve it?
