Gtg gas block - SLR Sentry 7 .750 Adjustable Gas Block w/ .450 in. Set Screw Spacing

Alright, so the gas block is premium. The fit and finish is second to none. I was unsure what to expect, but it really is a manufacturing work of art. The tolerance was tight, it practically stays on the barrel without set screws. I am really impressed with the product, but SLR is a disappointment. I have been to reaching out to them by phone, email, and even Facebook. Nobody ever responds! In two months I have yet to receive any for of communication from anyone at the company. My only grip would be with the company’s lack of customer service, the product is excellent but if something where to go wrong I would be SOL. I value good customer service and they fail miserably at it.
