Poland is another step closer to issuing the new MSBS 5.56 (AKA the GROT) as the rifle completes its first round of operational testing ahead of schedule.

Milmag report that samples of the new rifle completed the first part of qualification testing on 11 October, five days earlier than scheduled. The MSBS 5.56 / GROT has been issued for troop trials along with FB Radom’s 40mm underbarrel grenade launcher and the GROT’s bayonet.

Interestingly, the grenade launcher being tested appears to differ from from FB Radom’s concept design. With its trigger in the more traditional position to the rear of the grenade launcher’s receiver rather than forward, beneath the tube. The two are compared below:

The Wojskowy Instytut Techniczny Uzbrojenia (WITU) – the Polish Army’s Military Institute of Armament Technology – is due to carry out the next round of acceptance testing by the end of November 2017.  The newly formed Wojska Obrony Terytorialnej – WOT (Polish Territorial Defence Force) will receive their second batch of GROTs in December. In total 53,000 GROT rifles and carbines have been ordered in a contract worth 5,538,400 Polish Zloty ($1,540,000). In 2018, both the WOT and the Polish regular army will also begin to receive MSBS-5.56KA1 / C16 FB-M2 carbines.
