TFB friend Lionel attended the recent B&T Police & Military Day 2015 event, and covered some of the products exhibited there. The host, Swiss company B&T (formerly Brügger & Thomet AG), of course brought a large number of products to show off. Lionel writes:
Brugger & Thomet company the more weapons it produces, it is known worldwide for the quality of these accessories. So she has accessories for the most common weapons (HK MP5, M4 / M16, HK 416, SIG, B & T TP 9, B & T GL 06, AK 47, AK 74, M2, Minimi, etc … In addition the Swiss firm is recognized for the quality of its moderator [suppressors].

B&T-augmented weapons, including an M4-style AR-15, MP5, AKS-74, and Minimi. B&T’s very short suppressors have been mounted on the guns’ muzzles.

The rifle is marked “M4 Carbine”, but doesn’t feature the familiar Colt or FN markings, and appears to sport B&T’s logo instead.
Thanks, Lionel!
