I understand that you can you can use a F/A BCG in a semi AR 15, but not vice versa as stated previously. Also, that the F/A BCG is heavier.
Let’s put the legal issues aside (discussed here as well as other threads). I have just 3 questions, but I’m sure more will arise.
1.) Would there be any benefit to using the F/A over the S/A carrier in a semi –AR15? Pros & Cons? (same price – so that’s not an issue)
2.) Concerning LMT – There’s a $156 difference between the Enhanced BCG vs. Standard BCG, worth the difference? (see LMT note below)
3.) LMT vs. BCM ($130/$129) I understand that the BCM is MPI tested, and I was under the understanding that the LMT was as well, so what would be the choice between the 2?
LMT notes on their site that the Enhanced BCG, “Includes both our enhanced carrier which incorporate a longer dwell time allowing barrel pressure to be greatly reduced and promoting easier extraction, and our enhanced bolt which has a more resilient coating and stronger heat treat, as well as the cartridge case being fully supported by the bolt face. For usage with full-automatic rifles.”
