I See alot of People have a hard time getting kills with the concussion rifle, well im here to give you my strategy of doing it. First of all go to Big Team Infinity Slayer. make sure you have “Requisition” as your Tactical package for your load out you choose. This will give you a higher chance in Getting the Concussion Rifle. its not rare to get either, its just as common as the Needler or Saw. once you get it, i recommend you stay in tight corners, my favourite place to rack kills would be Ragnarok & become noticed by their sniper. They walk in, i land 3 body shots & boom, you have a kill easy. If you do this. you could average 6 to 9 Concussion rifle kills per game. Not much but its something. If you have any Strategies that you would like to share, please feel free to share. 
I’m on Expert, with 70 out of 75 kills, with the Concussion Rifle.
I think it’ll be the last Covenant Ordnance I’ll get done, but I’ll definitely get it done eventually.
It works very well for me in Infinity Slayer. Sucks for me in BTB. You definitely have to be patient with the gun, with those corners, and ambushes. Requisition and Ordnance Priority in Infinity Slayer for me helps the best.
i believe it spawns near the edge of the map near where you land from a man cannon on adrift so if you play team slayer on there over and over you should be able to get it and get plenty of kills once you learn the spawn timer.
My strategy when I obtain the concussion rifle.
Mobility and Ammo
Adrift- depends on your play style, I prefer passive, just stay near your team and bait the “lone wolves” into tight corners and blast away.
Haven- the same except patrol the tunnels instead of the top floor.
Make sure you pace your shots!
Don’t spam, you’ll just waste ammo.
There is a reason i have this stance before you guys. I swear, BTB is the place. Exile by Banshee spawn, a concussion rifle will come up randomly within 3 to 6 mins of gameplay. if it doesnt come up within that time. highly unlikely it will come later. But in order to get them to come to you, make yourself noticeable on their map. Also, do not use Ordinance priority. it doesn’t give you much of a chance to get a Concussion rifle; Requisition does. Please, try my Method. You will soon realize this is the easiest way compared to Team Slayer. i Tried both, i know which works faster. BTB takes it regardless.

why did you ask people to share their strategies if you were just going to say “my way is the best way”?
no offence but maybe slayer works better for some, it is definitely better for me and it is the last stance I need.
I ask for that mainly because i want to hear other peoples way, so other people can see their way of doing the mastery. Depends really on how comfortable they are with the Game type. I know my way is the best because it completed the Concussion rifle 2x faster that Infinity Slayer 4v4. I have my Reasons for why Big team is better & alot easier than Infinity, but for those who would rather use The 4v4 with “Ordinance Priority” instead of my way ( Big Team with Requisition) Then go right ahead.
My theory for mastering the Concussion Rifle?
Wait for an Action Sack playlist to showcase this weapon. Just as I did with the Incin, Binary, Fuel Rod, Rockets, Railgun, etc…
Or just lead the shots, works perfectly fine for me.
