Longer Inner Barrel for My SIG 552
 

I want to get a longer inner barrel for my SIG 552 so that I can get better range and accuracy. I'm looking at the Prometheus 6.03 EG Barrel For TM Type 89/VSR-10 (433mm). The length of my silencer is just enough to cover it completely. But can I use this inner barrel on my SIG 552 and will the notches on it be the same as my original inner barrel?

You can not use Spring rifle barrels for an AEG.

Get an AEG barrel that's near that length.

Thanks man! I didn't know that barrel was for a spring rifle. Thanks for the link.
