SOCOM 300SPS Cover Suggestions?

I finished modding my DD4 300BLK SBR and will receive my SOCOM 300 SPS next week. I've been looking at covers now for about 3 weeks and have a few in mind, but I was curious about the feedback from the Reddit NFA community. Here's what I've considered so far, but feel free to offer up others:

• Cole-Tac Corset (not HTP because it isn't recommended for SBRs / leaning toward this one)
• Liberty Defense straightjacket (Though this is my last pick; expensive, and not sure I'm fond of the look.)
• Precision Underground
• Burn Proof Gear - Heavy Cover
• HAD Suppressor Cover

MODS: Sorry if my flair is wrong... I'll adjust if needed.
