I want to give Boone a sniper rifle!

I put the gun in his Inventory, but he still uses his own rifle?

How do I get him to use the sniper?

Also, can I put the suppressor on it for him to use as well?

Last question, If i fully repair the sniper for him, will he do more damage?

Thank you so much!

Have you also put some ammo? Companions need ammo for all weapons except their default. And is the sniper rifle repaired to a level, where it deals more damage than Boone's rifle?

He should automatically equip it. A t least for me he has,,but he may switch at random.
Any modded weapon can be given to NPC....but Boone and stealth hardly go hand in hand.

Edit ninjaed !

Make sure Boone has plenty of ammo...he will go through it like candy.

Currently Boone has the All-American with 5.56 ammo, and a Sniper Rifle .308 ammo. Both ammos are pretty common. He seems to prefer the All-American but if I take it away, he equips the Sniper Rifle. I make sure he has lots of ammo for both...and it's a lot of work because he takes most of the shots. I prefer it that way though.

I'm having the same trouble with the antimaterial rifle (I think that's right) - gave him the gun and ammo but he doesn't use it I gave it to him because my strength isn't high enough to use it properly - does that matter at all?

On the suppressor question: for some reason if you give him a silenced sniper rifle it becomes magically unsilenced when he equips it. It's pretty lame.

Lately in my game Boone keeps using melee weapons that I dont use and just make him carry. Im like "your default gun has infinate ammo right? why are you using a melee weapon!?".Hmm maybe its his tactics,I thought he was long rang by default so I never bothered with his tactics.

I've got the same thing happening. It never happened though until I had him do melee once. I changed him back but now he often equips a melee weapon and then changes to his rifle. No idea why. ???
