MFT light, just enough to ID bad guy prior to body part removal. Had it on bottom, might return it there. Home defense role, inside house very close range. Sig Romeo 5, great sight! Instant on. Both eyes open red dot floats in the air on target. I removed Troy and Magpul flip ups because I realized if Romeo takes a dirt nap I’ll simply point and click, or look through Romeo’s corpse as a giant ghost ring. Kydex from Kel Tec and CDS Tactical neoprene protect my handsome face. Big improvement when shooting in 20 degree weather! Kel Tec sling works great. This is for HD and a range toy. I own MANY shotguns, including both Mossy SW and Rem Tac 14. I love them all but this thing is amazing. My home made grip plug made from thin plastic is an experiment. So far I can’t shake it loose and rounds down range will hopefully confirm. It will only hold a zip lock filled with watch batteries and an Allen key for Romeo so no real weight to knock it loose. I bought a PAST recoil pad for range use which makes a huge difference and I won’t feel recoil if I need to use it in defense of my family. Clint Smith wears a recoil pad and that’s good enough for me. I can’t see adding stuff hanging off the sides since this is made to be so compact. If I need more rounds than the 15 rounds it holds in my home then I’m in trouble anyway. Great forum BTW!
