Okay no one cared abuot my AR-10 post last thread do i'll just dump everything here

I need to build an AR10 for hunting, it needs to be light, i already have the optic
>why an ar10
because it has to be a semi and light and good price , idealy around the $900 range, target weight around 8lbs
>why not a boltie
i love bolties, i already own mutilple bolties, but it's for someone who struggles with a bolt action

I'm really not the most knowledgeable when it comes to ARs, so even less AR-10s

So i already did my reaserch, i'm going to go for a 16 in barrel with a 3 prong flash hider, but I don't know much else honnestly

I want:
>a good trigger, only item i'm going to really splurge on
>a good upper that is not too exensive, good quality, not too heavy
>a good place to buy / compare lowers, maybe one that's ambidextrous for not too much money ?
>otherwise items to make a non ambi rifle more adapted for ambi use
>a good mlok handguard
>i already have a stock / grip (A2 / sopmod) but anything good ? Light ? MOE stuff ? Again, much more of a woody gun fag

Is there anything i should watch out for ? Pretty much all my AR 10 knowledge comes from AR 15s, so if there's any other big difference, lmk
Is there a big difference in term of flash / sound when it comes to 16 vs 18 barrels ? I'd be ready to get an 18 if there is a large difference

Weird questions i know but tldr it's for a disabled woman who wants to go boar hunting

Thanks anons
