Specna Arms - Feeding issue on some mags

[Mik3F]

It looks like my Specna Arms doesn't like some mags and will miss feed every dozen or so rounds

 

Any one know what the quixk fix is?

 

It does it on my EPM1 mag and a Krytek

 

The Specan Arms and Hexmags all feed fine

 

Is the velcro in the magwell and or tape on the magazine a decent fix?

Simple answer is used the mags that work, I've a couple of pews that are mag fussy but it's never been an issue.

Pretty standard airsoft experience tbh. The velcro on the magwell is a good fix, but can also cause complications. As Gavin said, best to use the mags that work to save fixing one mag and causing issues with the others.

Guess I will do that then

 

Got an Amarok on the way to try out and if that does the same, guess I will buy some Specna ones

Yup, it's a common issue. Airsoft "STANAG" mags can have significant differences in dimensions, particularly the location of the feed. For example, one of my Specna mags vs the 'Nam style shortie mags that I use when I'm DMRing.

 

 

Knowing this, I determined that I needed to add 1mm on the front of the shortie mag with tape/velcro, and as a consequence, shave 0.5mm off the back. Notice that the Specna also has a conical feed lip, while the shortie has a vertical one, so I also gave mine a slight bevel with a dremel.

 

Observe, measure, and modify.

I love that sound-byte. A career on North Norfolk Digital beckons!

Another cause is how high/low the magazine sits relative to the hop unit and it's a combination of lower receiver, magazine retention latch and hop unit itself.

 

In fact good hop units have adjustable feed tubes to compensate for this.

 

In any case EPM1 mags seem to give more issues than benefits
