Buffer weight and spring for suppressed 12.5" AR-10?

[AK4900PA]

My Large frame build is finally complete minus the buffer and spring. Anyone with a similar setup? I'd appreciate hearing what's working for you

Aero M5E1 receiver set
KAK 12.5" .308 barrel
KAK double ejector BCG
Magpul UBR Gen2 stock (A5 length buffer tube)
SLR Sentry 7 adjustable gas block

I've been wanting to try the Armaspec SRS, but I'm also considering an H4 carbine buffer with Sprinco orange spring.

The gun will be shot exclusively suppressed with a Griffin Paladin. Functionality unsuppressed does not matter to me.

Consider ditching the buffer & spring system. Using a JP captured spring system in 14" Knights SR-25 ACC suppressed.

Sprinco Red spring and H1 buffer.
