SBR reviews. Please weigh in!

I don’t think I need to apologize for what I said but maybe how I said it. The post did have attitude and a harsh tone. I am self employed and like to see all companies do well, especially small ones. I am not familiar with NDZ but reading this thread I got the impression the product is clearly not market ready. Their web site says it is. It seems to me this is another case of someone rushing a product to market before it is completely functional. An all too common occurrence these days in many product categories. If I am going to be a beta tester that is fine, as long as I KNOW I am beta testing! That’s all I ask.

In this case we are talking about a rifle accessory. I stand behind my comment and OPINION that any accessory that causes my bolt to malfunction WHILE my finger is still inside the trigger guard is dangerous.

That’s my .2 cents worth. That is all it is. But my bolt stays open after the last shot EVERY time and my mags release EVERY time.
 
i am not 100% happy with NDZ releasing a product that isnt ready but it does make me feel better that they are standing behind it and providing the follow-up needed. in case you forget, even the major gun companies have all released firearms with issues but the ones that are successful are the ones that followed up on it.

is it a flaw that the bolt doesnt lock open on an EMPTY mag? sure. is it dangerous? not necessarily. i would be a lot more upset if it affected the performance of the rifle while firing but it doesnt. yes its an accessory but so is just about everything that people add to their rifles. it works just fine from the factory but we all feel the need to personalize.

i agree that i would never modify my rifle's function for an accessory but ill give NDZ a chance to correct their flaw. if not, then i expect my $ back and ill move on.
 
Back to the original question. I too installed the SBR, got to shoot some rounds, but did not do a full test. I'll be doing that this Friday the 13th. I did not have any failures, the bolt latched up, SBR did what is was suppose to do, speed up re-loads, help bolt up on rapid bolt checks and held the bolt back on the last shot with the SBR attached. The added weight of the SBR did not affect the bolt latch function at this point. I will update this post after 7-13... Good luck..

For ones who are having that issue, make sure the bolt latch is clean and lightly oiled so it is free to move from the magazine insertion as well as the bolt latch itself. Maybe added weight and dirt is causing some to have no latch up on the last round. Again Good Luck.

Well said. I made this thread as a litmus test for a new product, not to debate the merits of aftermarket add-ons. To each his own is what I say.
 
Gentlemen, wooo... This product is pretty simple in design, it is not rocket science. This product does work, it works on my M&P 15/22. Before we throw anyone under the bus, each and every weapon is different and we have no way of know how many rounds in one person's weapon from anothers NEW weapon. If the weight off-sets the bolt latch, then EVERYONE that installs it may have the same problem, that is not the case here. I've communicated with Paul and I am going to run the SBR into the ground, so to speak, this 13th with some solid testing on a range. I'll update accordingly.. NDZ makes some great products and based on my several purchases and emails with Paul, I believe he is very concerned about hearing issues on the SBR. And PS, NO I don't work for NDZ, I'm just a customer... Hang on guys, I'll post the results in week...
 
Yes, I agree, it is simple in form and function. The problem here seems to be one of clearance. In talking to Paul it seems to be thousanths of an inch. This means that any slight variance in materials in the gun, paddle, spring, etc, could cause different guns to operate with different results. NDZ wants to put a product out that can work with all 15-22s, therefor I'm sure they want to address the issue. It's been tested by several with varying results here. The definitive conclusion is that there is not enough clearance and it is defective on some. If it works on yours that's awesome, but it doesn't mean the product isn't defective. Like I said in earlier posts, Paul seems like a stand up guy and the company has been sterling so far. This is not an indictment of NDZ, just honest consumer feedback.

Please post the types of magazines you are using and what results you get. I'm just curious because the SBR works fine with my short and long 10rd mags.
 
It appears that the mag release paddle has to be removed for the SBR to be installed. Is this correct?
 
I am using the 10 round shorty, 10/30 round long mag & the 10 round long mag. My SBR works on all of my mags. NO the bolt latch does NOT have to be removed, it can be installed on the rifle as is.

It may be the way some installed it. I dis-assembled mine again and I think I know what may be going on. NDZ made the SBR cutout aluminum upper to fit the thumb pad of the latch, it is very tight I've notice. You have to fit the SBR and use a pliers (tape the tip so you don't mark the SBR) smash the SBR and paddle with the pliers together around all the edges, then install the screw and back plate. You may have the SBR crooked and angle in to much if it's not completly pressed into the latch pad.. and NO the SBR is not touching the receiver in the LATCHed up mode. Look at PHOTOS:

Update: Some have mentioned the bolt latch spring may be to weak. It is a light spring designed for just the bolt latch to remain UNLATCHED ONLY.It's the MAG spring that pushes the mag follower on the last round that is what forces up and catches the bolt latch up to the bolt, so you really have only ONE spring doing the deed, so to speak, it's the mags that give the latch & SBR the power to latch.

If you had last round latch up issues prior to installing the SBR, you may have more now that you installed it. So know your rifle's issues prior to adding on this device.

One note to those who don't believe in the SBR or BAD lever. It's not for everyone and it's not a device that is installed and magic happens with it. It is a device installed to speed up mag changes and assist in clearing jams when racking the bolt allowing your TRIGGER hand to stay in position NEAR the trigger during a gun battle. What is needed when this device is installed is TRAINING and muscle memory with more training. Add this together with the SBR and it saves time and lives in the field..

Like many (most?) accessories, it's not for everyone. For those who need it, it's great, I have no doubt. I may actually break down and buy one. It's certainly more useful than the takedown and pivot pins with extended heads on them. :)
 
In competition the BAD lever can shave hundredths off a reload. It could be the difference between first and second.

I'll probably be getting one. Does this failure happen with either a modified BAD ora 15/22 with an enlarged triggee housing running a BAD? Is it a problem with this design or trying to do this on a .22?
 
simply separate the upper/lower and the paddle is encompassed by the 2 pieces of the SBR and held together by a small screw.

as for last round issues, i never had any until i installed this item. i have since removed it until i get further follow-up from NDZ.

I'm not convinced that losing last round hold open and repeated accidental bolt releases are improvements.

keep up the productive posts.
 
I sent mine back on Friday and the guys at NDZ shipped it back to me today. I'd say that's pretty good turnaround. I won't be able to live fire test it until next week but I will update on the perceived fix when i reinstall it
