I'd value it 30-40k. I'd want to double check the decay if I was buying it. I've purchased a number of rare guns - mod lr32 and ml35me - which had the wrong decay listed on entropedia. I am sure the owner tested the decay correctly, but it's always wise to double check before buying.
30k + or - 5k as it is in eco between an mm and an imk2 but range is 1/3rd of imk2 and dps is only slightly higher then imk2. Will serve a good purpose for those who cannot afford imk2/mm yet
Very similar to i2870/i2870sga. Recent auction sales of those 2 guns were higher tiers, so if we factor tiering costs then a tier 0 i2870 is arounf +15k and the SGA around +20k.
This gun closest to i2870 so +20k up to +25k if you prefer the better eco over the better speed and range of the SGA gun
edit:
This month i2870 tier 8 (over 13k of tiering costs) sold for 21.6k
This year a tier 7 sold for +25k and a tier 6 for +16k (big difference there)
i2870 SGA tier 6 this year sold for +27500
This is just auction data, no idea if it's real or if private sales are any different. But +30k for the augumented at tier 0 looks a bit steep for me.
The base dpp of the i2870 has always been a little low for an eco gun at 3.020. The Augmented at 3.128 is massively higher; like strapping a 2% crit scope on the i2870. I think 15k for a i2870 tier 0 is still possible, and 30k the Augmented would easily sell at.
