I just recieved a 458 Socom upper and placed it on a DPMS lower reciever. Took it out to shoot it and I am getting a double tap each time I pull the trigger. Do I have to replace anything else on my lower for the upper to function properly? The lower works fine with a .223 upper. Thanks

No, nothing needs to be replaced. However, since the .458 SOCOM does recoil a bit more than the .223, I suspect therein lies the problem. A worn trigger/disconnector/sear would be the most likely suspects. Has your rifle received a "trigger job" of any sort? You may need to replace any parts that were worked over. While OK for the light .223, the .458 may be a bit much and be causing the malfunction.

I'd suspect the trigger group is the culprit as well. Maybe swap a NIW one in and see if it solves the issue. You should not have to do this, but maybe yours is worn a bit..... HTH........

I would recommend you don't go cheap with the FCG (Fire Control Group). The .458 does stress the system so high quality parts are necessary. I would recommend a FCG from one of the big three.

Thanks for the replies... The trigger group should not be worn very much on this as it has only had a couple of hundred rounds through it. It was a kit from model 1 sales on my lower. I will try a new trigger assembly--any brands I should consider?

Armalite, Bushmaster, or Colt.....maybe RRA single stage, or DPMS single stage.

Yep...A, B or C... I'm running Bushmaster with no problems.
