EngrBob Posted September 19, 2016 Report Share Posted September 19, 2016 For this hunting season I built a 6.5 Grendel to use when humping the hills and brush of South Texas chasing the wily deer. When siting in the Grendel, and testing the build at the same time, the first trigger pull resulted in a triple fire, yes, three shots fired with one trigger pull. The good news is that the three shots bracketed the target (1.5" group at 50 yards), but I don't need full auto for hunting. I tried again to see if the scope was OK at 100 yards and held the trigger back and it only fired once, but failed to eject. The trigger is an AGL (which I will be replacing with a Geissele G2S that was delivered over the weekend) but which has worked in other builds. The spring and buffer are standard and came with the 6 stop tube, completed with a Magpul MOE stock. It is a mil spec upper on an 80% polymer lower using a mil spec lower parts kit (except for the trigger). The gas is mid length on an 18" barrel with a lightweight low profile block. The BCG was very wet, soaked in Mobile 1 for a week before heading out. It may simply be associated with the fact that it hasn't been fired and needs to be broken in, but any suggestions of a testing protocol are appreciated.

98Z5V Posted September 19, 2016 Report Share Posted September 19, 2016 Trigger. Think you bump-fired it? Are you absolutely positive that the buttstock was tight into your shoulder, and that you held the trigger to the rear after recoil? Quote Link to comment Share on other sites More sharing options...

Buttstock was tight against the shoulder both times but I am only conscious of holding the trigger back on the second attempt when it only fired once. I could have released immediately on the first one. Quote Link to comment Share on other sites More sharing options...
MikedaddyH Posted September 19, 2016 Report Share Posted September 19, 2016 Look for a primer which may have fallen into the FCG pocket. This happened to me and Hemi's son Josh. Quote Link to comment Share on other sites More sharing options...
