Thank you, I know with the standard 7-position A5 tube, you cannot fully collapse the SBA3 brace, wondering if the 6-position is better? I also put a request in to Vltor so I'll post back and let you know what they say.

Some quick tests:
7 POS A5 = 5 total clicks of adjustment, at longest extension the #2 can be seen on top of RE in front of the leading edge of the brace. Roughly 13 1/8" lop on a tape measure with MBT trigger
6 POS A5 = 5 total clicks of adjustment, at longest extension the #1 can be seen on the top of the RE in front of the leading edge of the brace. Roughly 13" lop on a tape measure with a USGI trigger.
Neither combo had what I call excessive over travel, whereby the brace can collapse so much it's fully in between a notched position. Both braces could slightly over travel a hair but nothing that would cause a false lock. I really couldn't see much of a difference between the two RE in this combo other than the numbers exposed on top of the RE, which don't mean all that much with the SBA3. The slight lop difference may just be the different triggers used, or just my tape measure techniques
Side note. With a Magpul fixed carbine stock and the A5, not for pistol configs, the Re-10 has a shorter 'nose' for the adjustment channel under the RE and the fixed carbine stock can, in some cases, be pulled to the rear a little if the cross bolt tension screw isn't really tight on the stock.
Side note #2. Large frame lowers for AR10/LR308 etc can be longer dimensions behind the trigger, depending on specific make, that contribute to longer lop for anything attached to any RE.
