So i just finished my first AR build and I gotta say its been alot of fun and out of all the firearms in my safe I think its probably my cleanest shooter. I was wondering if anyone else has built these and has some advice on problems or concerns that they have ran into down the road. Here is what i built Plumb Crazy Lower Bushmaster 7.62X39mm upper 16" with izzy brake. Magpul Grips Wolff XP hammer Spring Enhanced Firing pin MOE handguards with 45 degree offset sight attachment with red dot 3-12 30mm scope 2 bushmaster 30 rd magazines 1 5 rd magazine I plan on using it for deer hunting this year. if anyone has any experience with an AR15 like mine and has any info on how it did hunting i would appreciate hearing about it.
