View Full Version : SAW with 30 round magazines

How well does the M249 SAW handle 30 round magazines?

Most of the time they suck feeding from a 30 rounder. Its a back up only meant for emergencies.

Yeah generally not good, especially from some of the crappo magazines you still see floating around.

When shooting blanks, expect to get double, triple and quadruple feeds on a regular basis, they just plain suck. However when shooting live ammo, its still problematic but not as bad.

I could never get it to work either. better luck throwing the rounds at the enemy.

I only tried it a couple of time and each time my SAW ate the rounds from magazines just fine.

what about Pmags? Were the failures mag related or the weapon just doesnt like feeding from mags period

In my experience, mags work pretty well in the SAW and it's a very handy capability. Not the ideal situation, but if your SAW gunner runs out of link 5.56 at least he can stay in the fight.

Its really hit or miss. Some SAWs could feed perfectly with mags and others it was a malfunction ever couple of rounds.
The whole magazine feeding of the SAW seem more of an afterthought that was included to meet the requirements of the gun that the DOD wanted. Then again it was more than likley designed by an engineer and we all know that they cant desgin stuff on paper and have it translate perfectly to a final product. Look at the EFV.

Interesting how it's so hit or miss. Could it simply be mag related?

The SAW is pretty hard on magazines too. Seemed to chew the feed lips up pretty badly.

Probably works just fine with steel body magazines but that isn't what we issue.

Push forward and up and they will be just fine.

My saw wouldn't get through more than 3 rounds

Some of the time it may be due to a **** magazine. But more commonly, it is due to wear and tear on the barrel chamber (erosion) or the gas regulator needs to be cleaned out.

When the 249 is fed from the belt, it uses the top of the bolt to feed into the chamber. The chamber of the 249 has multiple ports for being fed from belt or the magazine. Check your chamber on the feed side for burrs or dents. Since 249s feed so many rounds through the primary groove (top), rounds tend to feed consistantly over time. As the barrel begins to erode after thousands of rounds, the barrel will be somewhat 'misaligned' with the bolt when placing a magazine into the magazine feed port. The barrel will actually sometimes sit too far back, causing rounds to scrape against the chamber wall and jam. In addition to inspecting the chamber of your barrel, check your bolt for damage. Some bolt damage can go unnoticed by operators because the bolt uses a different side to feed with a magazine.

If this does not help, check your gas regulator (if using the older style barrels with regulators). When feeding with a magazine, gas regulators are substantially more sensitive. Clean the regulator and change the firing rate to sustained (1). Also, NEVER lubricate the regulators! Just use a reamer and wire brush.

When in doubt, consult your unit armorer. He will have a gauge kit to check the barrel erosion and headspace used for annual PMCS.
