Re: 40S&W/10mm Lever Conversion

I did a little looking around and a AR-15 in 10mm is going to be a little bit steep.
The manufacturer of the barrel/receiver set caution that unlike most pistol caliber ARs the 10mm is higher pressure and impulse putting additional stresses on components. They have specific component and setup recommendations that aren't inexpensive.
Dedicated receiver set ~ $440-$460 (1/4 circle, requires Glock mags and compatible bolt) (side charger is more.)
.40 S&W/10mm bolt - heavy $250
10mm 16" barrel $200
Heavy adjustable pistol buffer system 5-11 ounce $120 (recommended part, 11 or 8 ounce extended buffers can be had for ~$25-$50.)
Handguard ~$50-$210 (Freefloat prices are all over the place, the ones from the receiver manufacturer are on the expensive end while no name unknows run as little as $50. The ones I favor generally run around $135.)
Generic LPK $45 and up
Charging handle $10 and up
Heavy recoil spring $15-20
Carbine style stock and buffer tube ~$45 and up
Castle nut $2
Glock 10mm magazine ~$25-$50
Muzzle Device or thread protector $20 and up
Sighting system $70 and up?

So while you might get away with $1100 if you were lucky and got everything on sale without much in the way of shipping and handling charges you're just as likely to be around $1400 for a quality build.
(The primary vendor is out of stock of most everything having just gone through a sale for the 4th of July I'm sorry I missed.)

9mm by comparison you could probably modify an existing lower for something like $100 for the insert $50 for the recoil system, (Say another $200 for the lower and rest of the lower parts), $300 for a complete budget upper in 9mm and another $20 for a 'Colt compatible' mag. ~$670 + sights, shipping and taxes.
OR you could go with the Glock mag compatible parts and wind right back up at about the same price as the 10mm.
