Advisory Notification Regarding the NDS-1948W welded “Uzi” receivers
It has come to our attention that three examples of this product have experienced failures in the weld attaching the front trunion to the receiver shell.
One of the guns failed after 4-5 round were fired, and the other two after approximately 60 rounds were fired.
All three firearms were built as Post-Sample Machineguns by licensed manufacturers.
The receivers in question were repaired by the customers before they had notified us of the defect so that there is no way for us to inspect the parts to see what the exact cause was.
Both customers were very happy with the product in spite of this defect, and did not express any desire to return them for replacement.
After an initial inspection of some of our in-house inventory we believe that the failures were caused by over-zealous grinding of the welds which thinned out the connecting material, rather than due to poor quality welding.
During our testing of prototype and production NDS-1948 receivers we have experienced zero failures regarding the welds.
We believe this to be an isolated incident, and this does not constitute a recall, but rather and advisory to our customers.
Please inspect your receiver in the front to see if the four (4) points that are welded to the trunion are experiencing cracking or separation. Also look at it from the top or bottom to see if the sides of the trunion area have obvious “dips” or depressions due to excessive dressing of the welds.
If you experience a failure in the welds; please notify us immediately BEFORE you attempt any repairs. We would like to examine the receiver (or pictures of it) so we can ascertain what is the root cause.
We (NDS and McKay Ent.) will repair or replace any receivers that experience failures of the welds, and will also reimburse your return shipping costs.
McKay Enterprises has stated that they will not reimburse customers for any finishing on the receiver. (Parkerizing, Duracoat, Bluing, etc.)
McKay Enterprises has initiated an inspection, rework, and testing regime on all remaining inventory of the NDS-1948W “fully welded” receivers, and changes will be made to the next production run to alleviate any possible problems in this area.
