New to posting builds - This being my first! :)
I plan on adding a small acquisition guide and/or some minor work-arounds for newer players. Happy Hunting!

Objective:

My goal was to take heavy advantage of this gun's, already high, base critical chance and further that. This is achieved through the several base damage increases that will work along side the massive critical chance and damage increases that come from aiming down sights for a minimum of 9s.

Alternatives:

Hunter Munitions can be swapped for extra Base/Fire damage from Blaze or Cold damage and Reload Speed from Chilling Reload. Personally I'll suffice from letting the physical damage types do the talking.

Other options could be swapping Vicious Spread out for Blaze to maintain some of that damage minus the expense of accuracy.

• P.S. Prime Mods can easily be switched for their base version! This may even save the cost of some Forma. This will be ideal for those who can't get their hands on these mods.

Acquisition Guide:

First things on your list should be Point Blank, which can be found completing Lvl 5-15 Cetus Bounties, and [Hell's Chamber] having a drop chance from from either Orokin Containers, found in Orokin Tower tilesets, or are rewarded upon completing a few spy missions on Lua.

Next up would be to start building criticals. There's a good chance [Blunderbuss] is already in your arsenal from just playing through the game; in the case that it hasn't appeared, this can be acquired upon completing any Tier 2 Spy Mission. Then there's [Ravage] which is best found dropping from Orokin Containers (similar to Hell's Chamber. )

Then we have Shrapnel Shot, which is granted upon completion of the Lvl 15-25 Ghoul Bounties in Cetus, and Laser Sight, which lingers in the market for a pretty steady price of around 10-20 platinum depending on your seller.

The order in which you get the last few is up to you, but here are some Wiki links to help you find out how to get those. - Fatal Acceleration, Vicious Spread, Vigilante Armaments, Hunter Munitions.

• The Prime Mods can be found in Baro Ki'Teer's shop for a variating sum of Ducats and usually around 100-200k Credits. These can also be found in the market: Primed Ravage, Primed Point Blank.
