I have a 2 year old new Bushmaster hunter ar 10
Shot it for first time this past week.( yea I know bought too many toys back in 2013 just now getting around to shooting it)
Accuracy is good but can stand a trigger upgrade.
Problem is when using 10,20 round mags don,t have any 5 rounders, it cycles fine till last 4 rounds (new magpol mags) it wants to load new round before spent casing is completely elected out of barrel,not guite a stove bolt but new round jams spent round in barrel. Happens with multiple new mags.
My thought is it might be overpassed?
Fired 120 rounds thru it with same result. Understand they need break in but symptom remains
Rifle clean and lubed.
What should I look for in solving this problem? Factory build so unsure of buffer,spring,ect. Used
Thanks for the help
