I'm having a bit of confusion about the variants of this weapon, maybe someone can answer these questions here.
M203A1 ~ There had previously been an unsourced statement on Wikipedia (we all know it's the epitome of reliability...  ) that the barrel was lengthened from 9 to the standard 12 inches. Is this true or not? I've never been able to find anything out and all pics I've seen of the A1 model show it still with the shortened 9 inch barrel.
M203A2 ~ I know it's "designed" for use with the M16A4 rail system, but can someone point out how the attachment method differs from the A1 model? I've seen pics of it attached to the A4 rifle, but the attachment points look to be exactly the same as the earlier model A1.
M203A3 ~ I saw this designation on a military weaponry site a while back. Is there an A3 version in existence? I've searched and searched, but found nothing on it. Is it real or probably just a typo? |
The American M203A1 grenade launcher is intended for use with the M4 and M4A1 Carbine. The 9" barrel and is able to quickly detach from the rifle, and be replaced by a Knight's Armament Company M4 RAS lower handguard. The Canada built M203A1 launchers a similar except it places the launcher lower to to accommodate the distinct barrel profile of CF C7/C8 series weapons
The M203A2 grenade launcher is intended for use with the M16A4 MWS (Modular weapon system). The M203A2 uses the standard 12" barrel, the grenade launcher has been modified to use with the Knight's Armament Company M5 RAS handguard and not the standard M203 handguard . It also can use range-finding optics for precision targeting. Yje receiver was modified to fit the Knight rail system with a standard M203 will not fit the M5 RAS handguard
