unforgiven Posted April 24, 2016 Report Share Posted April 24, 2016 If i'm reading this right the BCG is locked into place and 3 men and a boy can't pull the charging handle back.....If you are running an adj. stock.Close the stock,unlatch the charging handle.Strike the buttstock on something solid [get a small piece of wood put it on the floor]and slam the buttstock to the floor while holding the latch open and pulling rearward on charging handle.Happened to me with the Nickel boron BCG.Took 3 stikes for it to open.The rifle should not have a live round in it.......

dprice38444 Posted May 2, 2016 Author Report Share Posted May 2, 2016 after much procrastination.i studied unforgivens suggestion and determined that if the bolt face was not in spec,his suggestion would put me right back in the same situation if i slammed it on a surface,plus,might break some expensive parts. what i wound up doing is using one of those harbor freight type body pullers that i had in the garage,(1/4 20 threaded tip)went to ace hardware and got a 5 1/2 inch 1/4 20 bolt.put bolt in vise 1/2 inch or so sticking out,and beat the bolt head until approx 45 degrees. then took bench grinder and ground the bolt sides flat to the bolt shank,the upward bent tip, fit right into the carrier slot.popped stripped upper into barrel vise,3 shots with the slide hammer,popped apart.

jtallen83 Posted May 2, 2016 Report Share Posted May 2, 2016 Nice work! That sounds patent worthy, you could charge good money for cleaned up version. Make them for both 308 and 556. Quote Link to comment Share on other sites More sharing options...
dprice38444 Posted May 2, 2016 Author Report Share Posted May 2, 2016 the si defense upper had been nibx'd,didn't want to mess it up.had a design for a puller,but no more access to machine shop anymore.this was cheap and simple.barely a mark on the carrier Quote Link to comment Share on other sites More sharing options...
survivalshop Posted May 3, 2016 Report Share Posted May 3, 2016 Mortering the stock ( as described by Unforgiven )would have been faster , but you got er done . A lot of new AR rifles have this issue at first , even factory rifles . Most of the calls I get , there is a live round in the chamber , I tell them to keep their fingers away from the Trigger & go outside or to the range ( if they are not there already ) .
