MSAR’s XM-17 E4 variation of STG that accepts M-16 magazines.
We are offering a free stock magazine catch upgrade. All current E4 stocks were manufactured w a composite internal magazine catch. We are finding that this composite is failing in their assemblies causing magazines to become stuck or locked in the stock housing. The new catches are made of heat-treated stainless steel.
Please contact our customer service manager Paul Thomas for this upgrade.

NOTICE
Do not send gun receivers, barrels or bolt carrier assemblies. Only send your stock assemblies. If you have a stock assembly w a magazine stuck in it, we will properly remove it without damaging the magazine and return it to you promptly.
Even if your E4 is working perfectly, we advise that you take advantage of this upgrade.

AMMUNITION ADVISORY from TONY
To all STG-556 owners. I have said this before and I will say it again. If you are having ANY reliability problems at all with your STG-556, let me know and we will work closely with you to remedy the problems at our expense. If there are certain ammo issues with questionable ammo, we are willing to investigate the problems and try to remedy these also. We will do some extensive testing with some of this ammo and determine if it is ammo or gun related. We use Lake City, Federal, Winchester FMJ, and Remington 55gr for all of our testing. The reason why we use domestic ammunition is for the simple fact that we have a level of accountability here that you cannot anticipate having with companies located overseas, such as Wolf, Norinco, just to name a few. A majority of the import ammunition or inexpensive alternative import ammo brands are very difficult for us to acquire in steady and large enough quantity to establish an appropriate and accurate base line. We will however try to get some of it so we can perform some test firing with it unfortunately I do not believe I am going to be able to guarantee performance with certain brands. We will thoroughly document this testing with video and data collection to try and determine specific problem areas if there be any. As with any high end product, most times you need to feed a premium engine, premium fuel to expect top performance. Any of you who needs to contact me please do so. I am available for questions almost 24-7. Regardless of any outcome that we find regarding ammunition types that do not properly function we are committed to your safety and satisfaction.
