I considered many options when I was in the same boat. Finally settled on the following to conceal my old 16" AR fully assembled in my SUV for the last three years:
Any hard or soft case of your liking, a large gym style bag will attract less scrutiny and interest than a hard case for a weapon, guitar or other large equipment but a hard case will obviously protect the weapon more. I had a large hard case originally intended for a bass guitar and I just went with that. Did not need to modify the padding inside the case at all, mashing the case together worked fine and it was a cheap case that I did not care about. Some more expensive guitar cases feature locks which may deter anyone who may be riding in your back seat from poking around and ending up asking the age old question: “What the **** are you doing with a big gun in your car? That looks scary!” So for the purpose of concealing it from people you DO want in your car, a locking case may be best, but of course it may take marginally longer to access the weapon. Now, the good part: In order to secure the weapon from any lookiloos who may spy a large case in my vehicle in a dark parking lot and deduce that there is probably something pawnable inside, I routed some thick steel chain from Home Depot around a beefy mount in my vehicle’s frame for the rear seats. No cutting of any panels or carpet was necessary in my Expedition, YMMV. The chain was padlocked to itself at this point and then routed beneath the seat to the cargo area where the case lived behind the rear seat. A small cut was made into the rear of the case with a Dremel and a cutoff wheel and the chain was again routed inside and then through the magwell and out the ejection port where it was, again, padlocked to itself. The trigger guard would also work, or perhaps a skeletonized stock BUT even if the lower had an integrated trigger guard, the weapon could still be removed in combat effective condition without tools by anyone willing to rip it out by brute force. The trigger guard would probably snap off, possibly some portion of the lower, no way to guarantee it wont be good to go afterwards- unacceptable. So, magwell it was. Could be made faster and easier to insert and remove if you used braided steel cable at this point instead of chain, your call. Some people carry multitools with wire cutters and may be ballsy enough to hang out in the car they just broke into while they work through some steel cable… I know Ive cut 6-8mm steel cable with my leathermans in a few minutes… The way I routed the chain under the rear seat and set the case right up against the rear seat, nobody in or out of the car could see the chain unless you got under the seat. Again, takes longer to set it up every damned day and under stress it would seem to take forever to release BUT… This will secure it against a smash and grab robbery- most guys who go smashing windows in cars dont go in expecting to need to pick decent locks or cut steel chain- who brings bolt cutters to break into cars? So I may be out a window if I dont properly cover the weapons case with shit- clothes, mainly, but at least it shooould still be there. And though it may take another ten seconds or so to get in the back of the vehicle, open the case, unlock the weapon, lock the bolt, pull the chain out, grab a mag, gas up, grab the go bag with extra mags and medical supplies… I would still probably arrive on scene a metric shitload sooner than any LEO, unless we were extremely lucky. AND, I dont know about you, but I trust in my equipment and level of training, and not to derail a thread but simply to provide reason for all of this enterprise… I dont necessarily trust ever LEO’s. In fact I trust very few of them as far as their capability to respond reasonably and effectively to situations requiring the use of force. No offense, gentlemen.
Anyhow. Thats what I did. I now just drive a car with a trunk to simplify things. And I carry a well-built VEPR with a folding stock in a small, innocuous gym bag I picked up at Goodwill for the whopping price of five dollars. The bags just for carrying it to and from the vehicle. It doesnt win points with LEOs who stop me and search my vehicle after they hear that, yes, officer, I am carrying a firearm- but it also does not elicit suspicion from my neighbors. Can be just as effective with my AKs as my ARs… Learn to control and deal with the weight and recoil… Adapt the gear for different mags, etc… So thats something to consider… A folding stock-capable weapon. And yeah, I know about the Law Tactical adapter. I trust it about as much as anyone. Which is not. At all. But to each his own. Youre probably never going to need this anyways so. Eh.
Sorry I never took any pics of this setup. All told it was about $20 in chain, lock prices vary obviously depending on quality, gotta have some way to cut the chain yourself annnd if you rock a sweet, cheapie gym bag like me, like I said, you can find em pretty cheap. Just disinfect the shit outta it, naturally, if its used.
Good luck.
Edit: I know you were asking for a center console solution, sorry for not having one- but I do have a question that may alleviate the need for a center console solution… When are you going to be accosted while inside a vehicle and say A-HA! I know! Ill just pull out my CARBINE! Have you experimented much with a carbine inside a vehicle? Do you not carry your handgun at least in an area accessible from the drivers seat if not on your person? Could you not make better use of this handgun from the drivers seat to neutralize or at least subdue the threat until you could exit the vehicle, get around to the back and get your real weapon ready? Just some thoughts. Juuuust some thoughts.
