Though this list shows the complete inventory of available accessories, MSAR has taken customer requests for additional accessories in to consideration for the future.

*Please be aware that unless a part is specifically labeled XM-17 E4 or STG-556, all parts are interchangeable with most MSAR rifles. However, some of the older STGs (gen. 1 & 2) are only compatible with the E4 accessories after a minor modification process. If your rifle has a locking notch shaped like a loaf of bread, it fits in that category. An upgrade package is available for these customers; MSAR will cut the original receiver for $100, then additional accessories can be purchased. The original STG-556 stock would be rendered useless with this upgrade.
