Safety is paramount when dealing with firearms. If either of these recalls effect you, please stop using the product and follow the manufacturer’s instructions for returning the product for upgrade or replacement.
First, for the person who assembles their own AR15 comes this from American Outdoor Brand’s Battenfield Technologies subsidiary. It is the AR15 lower parts kit (Item #110114) sold prior to September 12, 2017 and marketed under the S&W M&P label. It only applies to the lower parts kit and not to factory assembled S&W M&P-15s. The hammer in the kit is missing a pin due to a packaging error.
Here is a picture of the hammer involved and the steps you need to take to remedy the issue.
The second recall comes from SIG and involves a limited number of their SIG716, SIG516, and SIGM400 rifles which may have an improperly heat-treated hammer in the trigger assembly.
Newington, NH (September 15th, 2017) – SIG SAUER, Inc. has determined that a limited number of rifles in the SIG716 DMR®, SIG516® Carbon Fiber and SIGM400® Predator models were built with a two-stage SIG SAUER trigger that may have an improperly heat-treated hammer. Over time this could result in a trigger malfunction creating a significant safety hazard. SIG SAUER is issuing a mandatory recall to replace the hammer and trigger assembly in these specific rifles. This recall does not affect any military or law enforcement rifles or any SIG MCX®/SIG MPX® products.
SIG SAUER will correct any of the affected firearms at no cost to the customer.
To determine if a specific firearm is affected by the recall, go to https://www.sigsauer.com/support/safety-center/rifle-safety-warning/ and utilize the serial number identifier and visual inspection instructions.
If you are a customer who is affected by the recall, stop using the firearm immediately and follow the instructions on the website or call SIG SAUER Customer Service by dialing 603-610-3000, option #1. Have the rifle’s serial number available.
To reiterate on both recalls, if you own either of the products involved, stop using them now and contact the manufacturers involved.
UPDATE: In an absurd posting, the Bloomberg-financed, anti-gun “news service” (sic) The Trace criticizes SIG over their safety warning and recall. They contend that SIG is “keeping gun owners in the dark” by just saying it can cause a “trigger malfunction” due to the improper heat treatment of the hammer. The Trace wants SIG to go into chapter and verse over what a trigger malfunction might cause. They point to the safety warning (probably mandated by the Consumer Product Safety Commission) issued by Takata on their air bag recall.
I think the average firearm user recognizes that they are a) using a tool that can have deadly consequences if misused, b) that a trigger malfunction is not good, and c) you don’t mess around with trigger malfunctions.
