har1690 Posted April 23, 2021 Report Share Posted April 23, 2021 Can't find any info on the bolt gap for the HK 23e/21e belt guns. I mean really. Does one follow the same bolt gap as the Mp5k thru the G3 series? Can't believe it but anyone have a link showing an HK 23e bolt gap spec. Thanks.

taylorwso Posted April 23, 2021 Report Share Posted April 23, 2021 .010" to .020" .015" is the sweet spot. I keep mine at 16-17 thou and run heavy springs and it will feed anything. Quote Link to comment Share on other sites More sharing options...
