Hello what are the positives in running a F/A BCG in a Semi Auto? I know it is larger and heavier but how does it add to reliability?
Thanks
I can’t tell any difference when using one vs. the other so 6 of one, 1/2 dozen of the other.
The M16 carrier was designed for the M16 & M4. Making a carrier lighter with the side effect being higher bolt velocities can only hurt its reliability and is well known with the M4 having extraction issues ect.
So why not run a same weight carrier as a full auto M4 for less problems?
GotM4, your wordking confussed me alittle(its easy to do) would you say a M16 carrier is more reliable in a semi/auto M4 configuration?
Yes!!!
Yes, as long as your using 5.56mm NATO pressure ammo. If you’re using 'who knows what?" ammo probably not.
Would the M16 carrier make a difference if using .223? I had a customer at the last gun show quiz me and I had no idea.
It will work fine with .223 pressure ammo as well. .223 Rem is loaded to lower pressures than 5.56mm NATO.
The weapon was designed with the FA carrier. To use anything else really doesn’t make any sense.

I always use F/A carriers & Hammers (with the leg that actuates the sear ground off… similar to the DPMS semi hammers) on builds.
Thoughts:
F/A carrier has the proper recipicating weight (semi is lighter)
F/A carrier fully protects/shields the firing pin (some semi exposes pin which can hammer drag)
-the semi, notched hammers are of lighter weight (enough inertia?)
-I think the notches add unneccessary friction on the bottom of the carrier
I’ve been using M16 BCG on my two carbines and 20" A2 rifle for the past two years and all runs great.
I had no problems with the semi auto carriers I used in the past for a long time but I decided to switch for better reliability.
