Yes, this has proven to be a great set-up. Almost 5 years in and NO regrets. The DPP is a tank and only wish it was easier to adjust brightness up/down. Otherwise it's been super durable and so easy to shoot with the dot. Nearing 10K round count.
Ditched the Comp as not much benefit IMO, but waiting almost a year now for Tax Stamp to use with my Griffin Arms suppressor.
