Get Spectre,
Open it up, (3 screws in the handle, 2 in the slide & 4 or 5 others)
open up the turret, (5 screws)
let the AR's and barrel posts fall out, (5 restrictors, 5 small springs, 5 barrel posts, all useless shit)
put it back together and you're done.
There you go.
It's better than an AR removed Maverick mainly because the seals are MUCH better in the plunger & the rotation Mech is much more reliable.
The 'barrel extension' is pretty cool. It doesn't do much but look badass on a longshot.
The folding stock is a novelty. I noted that it's about 3 inch longer than the raider's stock. Good if you have long arms I guess.
The whole gun is a lot easier to holster than a mav, being slightly thinner & significantly lighter.
If you have any questions about the spectre i'd be glad to answer them.
Special thanks to Chad for the b-day present. It was not expected at all.
