Simple IR reflectance experiment: Black, FDE, and Krylon’d SCAR’s from left to right; various polymer magazines on the ground. Passive image on the left and IR illuminated on the right. Not a scientific test by any means.
Tape it up
Polish soldier in Afghanistan with his Beryl. Note the forward pistol grip handguard and the non-transparent magazine. Looks like he’s wrapped up the side-folding stock in tape for some reason. Normally the Beryl stock has the metal tube sections wrapped in a rubber for comfort but also to prevent accidental burns when you consider patrolling in 100 degree heat and then putting your cheek against exposed steel. Maybe the rubber wrap on his stock came off, who knows.
