View Full Version : Range report M-249 & M-240B

First time shooting either weapon this past week.

M-249 aka SAW. Accurate as all get out jammed like mad. Probably a dozen jams in 200 rds. Switched to a different gun and still had several jams with the 2nd gun. It is no wonder USMC is looking at replacing it with an HK 416.

M-240B No jams but harder to hold on target. 6-8 rd bursts are about all that can be held on a point target.

Had a great time training with my marines can't want to go train some more.

I have no respect for the SAW. The 240 on the other hand, I only witnessed one failure, and that was due to an armorer failing to properly install the feed pals. 7.62 NATO can tear stuff up!

A properly maintained 249 runs well.

Problem is the USMC's M249s are all mostly shot to pieces and haven't been replaced with new guns (new parts only go so far).

I carried a 240 quite a bit and the 249 also. Didn't have an issue with either weapon in my case because we didn't ever get to light anyone up, but if the gun is properly maintained and not zip tied together (seen it.....) they'll perform.

Our armourers are young and don't know what they don't know yet. When the gun jammed prior to being replaced I saw a live round drop out when we finally got the charging handle to retract. Next attempt to fire same thing bolt stuck shut, I warn the young marine that I think a live round is in the chamber as he swapped it off the firing line. He claimed that was impossible since the bolt was shut (round should have fired), but humored me by keeping the weapon pointed down range while attempting to fix it. Round cooked off about a minute later.

Our 249's are in need of replacement, but the line units need the new guns so we make due with repair parts.

I wonder if blocking the magwell would improve feeding though. Two of my jams dealt with links getting into the magwell and not allowing proper flow through the gun.

Never had a problem with the 249 but that was in 1988 when we first got them. Those same guns are out there today.

Doing my time with the SAW never had a problem. They must be maintained just like any other firearm to be reliable. Most military firearms get run hard.

If you're getting links into the magwell, check the feed pawls and associated bits, they're throwing stuff places they shouldn't go.

Thanks for the tip MrMurphy I'll pass that all to the armourer as something that might be useful to look at.

I have carried both, and never had any problems with either. But need to be run WET. Use plenty of lube and make sure they are clean.

I always prefered the 249 though becuase of the nutsack and shoulder fire capability. When I had the 240 I had to carry unloaded with a box of ammo open and ready.
