Hello, I'm putting together an AR with all purple tint aluminum parts. The lower is Sendra, I believe the upper was made by Sendra as well, I'm not sure who made all of these purple tint aluminum parts. I have a purple slip ring but it is a dull finish and I would like to find one that is smooth like the other parts. I am looking for the following purple tint parts: slip ring / delta ring trigger guard mag button carbine buffer tube (commercial or mil spec) If you have purple parts that I already have I may be interested in them too. Here is what I have so far, in the background is a grey SP1 for comparison.
