An adjustable gas block instead of an adjustable gas key would be better for this setup however id like to avoid an adjustable gas block on this build so i made a new buffer that can accept 2 standard weights so i can load it up to 2.1oz 2.9oz or 3.6oz. Ill be playing around with that some more.
Last time i shot i took another picture.
Got some new parts in the mail yesterday, all PSA Custom bolt catch, safety, and mag release button. Shaved a few grams but more importantly bigger bolt catch extended mag release and ambi safety are all improvements in my book. Trying a different trigger as well, its from unbranded AR.
