I think you're on the right track with Wilson Combat.

AR15
Wilson SBR Tactical - $2450 with tax stamp.
Wilson Whisper Supressor - $1450 with tax stamp
Aimpoint red dot $750. Or Nightforce 1-4x scope $1500.

1911
Wilson CQB - $2865

Shotgun
Wilson Border Patrol - $1135

-------

Add slings, holsters, extra magazines and ammo. $1000-$1500.

Of course you'll need a safe. A good Liberty safe of medium size with be $3500 on up.

-----

For inexpensive plinking a .22 pistol and rifle are always a fine addition.

Here are two of mine.

Savage FV-SR and Ruger Mark III. About $3000 outfitted.
A couple cases of standard velocity ammo - About $1000.



-----------------

That will run through about half your funds. Need more help?
