Hello everyone,
I'm planning to start buying some BCG's while it's still a good time; although I'm going to be putting these away for farther down the road as either spares or for building up more stripped lowers.
I was eyeing the LMT Enhanced BCG among others, and the description says its recommended for carbine gas systems with barrels of 14.5" or 16".
Now the plan was to have it as a spare for a Defender 2000 upper receiver, although in the future I may have it rebarrelled with a mid length gas system. So my question is: would I have any issues running the enhanced carrier? Would it just be a safer bet to go with the standard carrier instead?
I tried reading through older threads on the topic of the LMT Enhanced BCG, and I found that there have been revisions to it through the years, although I was not able to see what year each revision was made. So I apologize if I mention something that has already been addressed in the more recent version of the BCG.

This lead me to thinking:
Is there any advantage to a carbine gas length 14.5" or 16" rifle vs a mid length gas system in the same barrel length? Provided that the rifle is of a reputable manufacture with a proper sized gas port. It seems that the trend among AR manufactures now is moving towards producing mid length gas systems in barrels of 14.5" and 16" lengths.
I have seen the statement repeated "a properly gassed carbine AR will run as well as a mid length gas AR". The key words being "as well as". But is there any benefits at all that a carbine gas length AR has over a mid length?
Or do manufactures stick to the longer carbine AR's simply due to military contracts/specs and the budgeting that goes with them.
Mods: if this should be split into two threads please let me know.
Thank you in advance for any contributions to the thread.
