I just built a 6.5g carbine using a Doublestar chrome lined barrel with carbine length FSP. I am also running a Doublestar star bolt. I am having 1pm ejection, numerous double feeds and FTEs per magazine. I am currently using C-products 28rd magazines and 10 rd magazines. Same issue with both mags. Currently running an H1 buffer with standard spring. Would it be beneficial to try an H3 to fight the over gassing or could it be a magazine issue? I am new to the 6.5 Grendel.
