Re: Bushmaster ORC 308 stock options
Buffer size isn't different. If you want to use a Ace stock use an Ace stock. The problem lies in buffer tubes that are shorter in length then rifle. The problem is the extra length of the BCG forces you to use a shorter buffer. DPMS's 308 carbine buffer is short but when you start looking at its weights you may run into reliability issues.
I've got a Mega MA Ten and put a UBR on, now I'm waiting for a buffer to get here from them. I'll get the buffer in the mail on Wednesday or Thurs but can't take it out till Friday morning. If reliablity becomes an issue I'm throwing the PRS back on till I can get a slash. I think I'll end up using the PRS for hunting this weekend, some how I have a bad feeling about the weight. Could be wrong though. Hope that helps.
ETA-Make sure you use a 308 buffer
