"Which brings us to the M40. Tried and true, battle-tested. Essentially the same rifle used by Marine snipers since 1966. It's light, accurate, good for soft targets in the 8- to 1,200-meter range. You seem to know this one."
"Oh, yeah. You could say that."
"That's the A1 model. There's not much change from the original. Biggest difference is the stock. It's fiberglass instead of wood. They changed it over in 1970 or so."
"Good. Wood warped like hell. You get it wet, put it in the sun, gone. Somebody probably should have figured that out before they sent it into a damn jungle.
Lawson and Mike Ehrmantraut[src]

The M40A1 rifle is a bolt-action sniper rifle and an upgraded version of the M40 rifle used by Marine snipers since 1966.


Better Call Saul

Season 2

While plotting to kill Tuco Salamanca, Mike Ehrmantraut enlists the help of black market gun dealer Lawson to buy a sniper rifle. After Mike rejects the first two options, Lawson suggests the M40 rifle. As Mike examines the rifle, Lawson notices that Mike appears to be familiar with the gun to which Mike comments "you could say that." Lawson explains that its the A1 model and it was changed over from wood to fiberglass in around 1970, pleasing Mike as wood gets "warped like hell" in the sun and "somebody probably should've figure that out before they sent it into a damn jungle." However, Mike changes his mind and decides on another plan rather than killing Tuco. ("Gloves Off")

Mike testing the M40A1 with Lawson spotting

Due to threats from Hector Salamanca, Mike decides to assassinate the old don and buys the M40A1 from Lawson to do the job. Acting as Mike's spotter, Lawson helps him make practice shots and offers advice. Mike decides to stick with the 168gr ammo rather than upgrading to 180gr. Mike later attempts to kill Hector with the gun, but is interrupted by his horn being deliberately set off to stop him. ("Klick")

Season 5

After following Saul Goodman as he picks up Lalo Salamanca's bail money, Mike rescues him from an ambush by a Colombian Gang, using his sniper rifle to kill all but Tiburón who escapes. After Saul's car breaks down, Mike carries the M40 with him through the desert in a bag while Saul carries the bail money. Following a rousing speech by Mike, Saul orders Mike to ready his rifle and heads into the middle of the road with a space blanket to draw Tiburón's attention. Mike's first shot misses, but his second kills Tiburón, causing him to crash his truck, rendering it useless for Mike and Saul to use to reach civilization. ("Bagman")

When Lalo Salamanca breaks into Saul and Kim Wexler's home, Mike covers them from a rooftop across the street with his sniper rifle until Lalo leaves. ("Bad Choice Road")


  • Mike's familiarity with the gun suggests that he may have been a Marine sharpshooter during the Vietnam war.
  • For some reason, Mike is never seen using a sniper rifle in Breaking Bad though this may be out of choice or lack of circumstance requiring one.
