MSAR, Inc.
RA #: XXXX
300 Chestnut Street Ext
Bradford, PA 16701
Yes. MSAR will still service STGs and original E4s. Please complete an RA and someone will contact you.
The new E4 parts and accessories are compatible with newer versions of the STG-556 and the E4s (squaure locking notcch). Generation 1 and 2 of the STG-556 (a loaf of bread shaped locking notch) will require some minor modifications to accept the new E4 parts and accessories. An upgrade kit is available for $100.00; with these upgrades the original stock would be rendered useless because of the minor modifications made.
MSAR sells majority of parts and accessories directly to consumers. However, the rifle itself, and suppressed barrels require proper documentation, and will need to be purchsed through a dealer. Orders can be placed online or by phone 814.363.9260.
We have dealers located across the US, and the list is growing daily. To view the complete listing, please visit our dealer page.
A dealer application can be found on our website. Upon completion of the dealer application, a representative from MSAR will contact you to discuss the requirements each of our dealers needs to meet. Please be aware that submission of the application doesn't guarantee dealer status.
The following websites are good resources to use:
- ATF State Laws and Published Ordinances - 30th Edition
- NRA-ILA
However, please note that although these sites can be a useful resources, they are not a substitute for the law. As gun regulations can change, the best way to ensure compliance is to follow up with your local authorities on the crimes code. MSAR does make versions of the rifle that would be compliant in some states, like New York; as of now, there isn't a California legal version.
MSAR is currently developing a 300BLK® barrel. Though we receive a lot of requests for additional calibers, our efforts have been focused on the 300BLK® barrel. Our research team is discussing the possibility of a 6.8x43mm conversion kit, and will be taking pre-orders. If enough interest is generated, the 6.8 kit will go to production.
As MSAR continued to develop, the STG-556 was upgraded to the E4. The Archangel was created as a prototype, but never hit production. Currently, MSAR has chosen to put its efforts into strengthening the E4 platform.
MSAR is in the process of configuring pricing for law enforcement and military members. Please stay updated on our efforts by checking our website and signing up for our newsletter.
We do get quite a few requests for a 20" barrel, as a lot of users prefer the longer barrel for improved accuracy. However with the extensive research and testing that went into this rifle, the 18.5" barrel proved to be just as accurate, if not more accurate than a longer barrel. The rifle was designed to be more compact, which is why the two offered barrel lengths are shorter.
