M4A1 Carbine

The M4A1 Carbine is an American made assault rifle, produced by Colt Firearms and FN Herstal. In the Henry Stickmin series, It appears in Escaping the Prison and Stealing the Diamond. Oddly enough, the rifles appear to lack a rear sight post.

Escaping the Prison
The M4 appears in the "Badass Bust Out" path (remastered version only), when Henry is surrounded by police Officers at the entrance to West Mesa Penitentiary. It is being held by Captain Ed Roberts.

During the standoff, he aims his M4 at Henry and shoots at him, resulting in a fail. If the screen is clicked just before he shoots, Henry dodges all the bullets being fired at him and catches one of them. He throws the bullet back, knocking the M4 out of Capt. Ed's hand.

Stealing the Diamond
The M4 appears in the "Unseen Burglar" path, at the final decision outside the backdoor. A security guard, Cliff Knux, is taking a smoking break, with his M4 leaned up against the wall.

When Henry takes his M4 and tries to shoot him, he misses all his shots, resulting in a fail.
