Are shrouded carriers found only in select fire guns? Can one use a shrouded carrier in a semi AR to "protect" all associated parts i.e. the cotter pin etc within the carrier?
Don't intend to hijack this thread but should I be concerned with the unshrouded carriers being in a majority of my rifles? I have never had any reliability issues with any of them...
Most don't have any issues except for the occasional bent FPRP.
The unshrouded carrier was a Colt idea (IMO not a brilliant one) for AR15 use only. If yours is running fine you don't have anything to worry about.
In the event of hammer follow with an AR15 notched hammer an unshrouded carrier is supposed to keep the rifle from slam firing. It does and it causes a bent firing pin as the hammer jams on the end of the firing pin.
The unshrouded carrier can only use an AR15 firing pin where as the shrouded model can use an AR15 or M16 firing pin.
Full auto carriers are all shrouded.
Ok so what size is the FPRP if i need to get one local say hardware or TSC in the event of, oops iam out of them and need them now.
Thanks for posting that pic GotM4! I checked mine right away. I have another request though: are you able to post a pic of what you mean by making it 90 degrees different than the firing pin? Do you mean that the two legs are vertical in the hole or horizontal in the hole? Much appreciated:o .

The hardware store cotter pins will not work for long in an AR15.
With the carrier laying horizontal the FPRP should be inserted vertically, one leg will be sitting on top of the other. So that the firing pin will make contact with both legs of the FPRP not just one.
Copy that. Thanks for your patience GotM4;)
