Should I put a Superlative Arms AGB on my 14.5 BII upper?
Is adding a possible failure point worth the tunability? Planning on shooting suppressed with an FRT. Currently have an LMT enhanced carrier, and also have a KAK DBC for FRT tuning. Looking to get a low ROF. Got a few springs and buffers for carbine and A5 lengths. But I can't decide if I should go with an AGB. From what I've read, the SA AGB is the only one that will fit under the RIS II. Thoughts?
