SBR - A5 Question

[Five_Point_Five_Six]

I've had good luck with the VLTOR spring that comes with the kits and found that spring and the A5H2 to be the ticket for *most* setups. The only gun I run a lighter A5 buffer in is the one with a Law folder, that little BCG extension weighs like 2oz.

Absolutely this. 2.3 oz to be exact.

I found with a 0.070" port 10.3" bbl and LAW adapter I had to switch to a 3.0 oz carbine buffer, and when I changed to an A5 I used the 3.8 oz A5H0 buffer. My dad's BCM 12.5 runs a LAW adapter with an A5H3 and Sprinco Green (total of like 8.3 oz). We've never measured the port, but it must have some serious gas to cycle all that weight (it runs like a sewing machine FWIW).

I don't have anything useful to add. I just found this post to be a reminder that after having the A5 system on my "to do" list since it's unveiling, I still haven't gotten around to it.

10.3" with the Crane spec .07" gas port, LAW folder, and A5H0 is the exact combo I'm running on that particular gun. I'm not shocked to hear your Dad's BCM is gassy.

I wouldn’t bother.

I wouldn’t bother.

I wouldn't either unless it's going in a new build.

If its on a SBR or pistol it would be one of the first things I do.
