I have a USR that is registered in CA as an AW. Can i buy a AUG stock and replace my thumbhole gray USR with it?

Since this 2000 postban/preban thing doesnt matter anymore..

there is also a conversion kit that will enable you to use AR15 mags...is this legal to put on my USR in CA?

Thanks for the advice.

If it is registered you can do whatever you want. None of the stuff like thumb hole stock or pistol grip etc apply. (Keeping NFA laws in mind, so not technically ANYTHING.)

922r STILL applies.

922r STILL applies.

oh yea, that law lol.

what is 922r?

You can't have more then 10 (i think) parts that aren't made in the USA. Stupid I know.

i dont understand......how does that apply to USR? isnt that already all foreign in the first place?

i can see if you are trying to make a clone...like a HK 91 or FAL...etc.

Gun laws are entertaining. And I thought car mod laws/restrictions were ridiculous.

ok...i found the info... thanks for reminding me about this. :(

Any additions to SKS and AK type rifles would
make them nonsporting firearms that would be in violation of 922. These
additions include: replacing the thumbhole stock with a pistol grip and
military style stock and/or modifying the firearm to accept a high capacity

In order to modify SKS or AK type rifles and avoid any violations of 922, you
will have to replace the foreign parts, except for 10, with U.S.-made parts. As
previously stated, no more than 10 of the above 20 foreign parts can be
installed after the modification.

You can remove the Night Sights, Grenade Launcher, Grenade Launcher
Sight, Bayonet, and Bayonet lug without repercussion as removal of items has no
bearing under Federal law."

Your proposal makes the following changes:

(1) Frames, receivers, receiver
castings, forgings, or castings.
(2) Barrels.
(3) Barrel extensions. None on SKS
(4) Mounting blocks (trunnions). None on SKS
(5) Muzzle attachments. Removed
(6) Bolts.
(7) Bolt carriers.
(8) Operating rods. None on SKS
(9) Gas pistons. Replaced with US part
(10) Trigger housings.
(11) Triggers.
(12) Hammers.
(13) Sears.
(14) Disconnectors.
(15) Buttstocks. Replaced with US part
(16) Pistol grips. None on SKS
(17) Forearms, handguards. Replaced with US part
(18) Magazine bodies. Replaced with US part
(19) Followers. Replaced with US part
(20) Floor plates. Replaced with US part

The resulting firearm would have items 1, 2, 6, 7, 10, 11, 12, 13, and 14

USR comes with a thumbhole stock which makes it a sporting rifle. You change that out suddenly it becomes evil ;)

Yes you can put an aug stock on and still be 922 r compliant but you have to search out us made parts for the aug. Luckily with the us made a3 parts and even some from msar this is fairly straightforward.

where can i find US parts? Which parts do you recommend i replace?
i have been out of the firearms scene for a while and dont know where to start?

gas piston, trigger, hammer, barrel, flashhider and mags are all available us made.

check out the bottom of this page where you can buy a kit to legally turn your usr into a compliant A3. a little pricey but a cool option.

Thanks! yes...that is way more than what i want to spend...but this is a great site i never knew about.

Actually - doesn't the ATF consider a thumbhole stock "non sporting" anyway? I'd contact ATF and ask them. Initially thumbholes were not pistol grips, but later they changed their minds - so what would it matter anyway? I'd write them a letter to get a definition.
