I'll apologize now, as I'm sure this has been asked before... but I haven't found the answer yet, so I'll ask it again.
I'm building an AR/M4 16" 1:7, Carbine-length DI gas... fairly standard parts; it's a budget build. Checked torque specs, headspace, etc...
Bought a Del-Ton Full Auto BCG, but a commercial CAR stock assebly... the buffer weighs just under 3 oz
Tested it twice, and am having a cycling issue.
testing went as follows:
1 round in mag to test for BHO after last round = good
loaded 10 rnds, cycled two rounds (3 shots fired), then FTF... rounds ejected & cleared, but failed to strip the next round off the mag (BTW newer mags, never a problem in my match rifle)
Pulled semi-auto Double Star BCG from my match rifle, tested in new M4 CAR build... loaded 10 rnds, fired smooth until end of mag w/BHO at the end...
Conclusion... heavier BCG does not cycle properly, lighter BCG cycles perfectly...
Aside from buying a new semi-auto BCG i nliue of the F/A BCG, what can be done to help the cycling issue? Heavier buffer? New buffer spring from Sringco?
Any advice from those more knowledgeable than I, would be greatly appreciated
