Free Float Question I Haven't Seen Posted Yet
I have spent the past week looking for information and have been unable to find what I'm looking for. I apologize if this topic was asked prior and my search skills are just not on par to have found it. I also apologize if this was the wrong area of the forums to post, at this point I am at a loss as far as if this would be "Ar General Discussion" or "AR Technical Discussion". Having said all that, here is my question:
Which type of free float rail barrel nut attachment provides the strongest structural integrity?
From what I've seen, some the most referenced brands on here are BCM, MI, and Geissele. The three seem to have similar mounting with a barrel nut that does not require (or requires minimal) indexing, 1-2 cross bolts to secure the rail to the barrel nut, and depending on make/model possibly a bracket to prevent rotation. How do these compare to the strength of the old Delta ring assembly (stronger, more/less secure)? A less popular option I've seen is the Aero Precision M4E1 where the rail collar is actually part of the receiver and holds the hand guard in place with 8 screws. Is this system weaker than the BCM/MI/Geissele or is there a different reason for its lack of popularity?
I'm trying to part an idea for an upper that would have the least amount of potential failure points as possible while providing the strongest structural integrity. I'm open to suggestions and I am NOT looking for confirmation bias. I'm here to learn.
Thank you in advance!
