I have a gloss black impulse. As for upgrades I know it has an evil bolt but that's it I believe. I just got it and played with it two weekends and the thing is just plain too heavy for my liking. Looking for 90 +shipping obo or trade for something lighter. Also willing to trade for higher end masks, hpa tanks with good hydro, or other gear like jerseys or pod packs. Jerseys would need to be 2xl and pod packs fit a 38-40 inch waist.
