Adding magazine extension for M4

[PK2229]

Hi all,

just bought an M4 model 11707. I had a question regarding 922r compliance for LEO. I’m active LEO and I’m wondering if being that I could have purchased a full tube M4 (would’ve taken nearly a year for it to come in, however) would I be able to install a magazine extension without replacing an additional 3 parts or does 922r apply to both civilian and active law enforcement ? 
 

I just want to be sure before I spend $300+ in upgrading parts. I would’ve invested in the M4 upgrade kit (replaces the hand guards, follower, and tube) just not a fan of the hand guards having to screw in to hold in place. Not looking to potentially mar the finish. 
 

thanks!

In the reading of 922(r) I don't see a distinction. It applies to whomever makes the modification. I wouldn't bank on it.

I've always wondered how a 922r compliance conversation would go down.
Authoritarian: Excuse me sir, is that 922r compliant?
Me: Do you have reason to believe that it is not?

I would assume the only reasonable way would be the ATF would have to check the gun and say “you have an extended tube as well as all parts made in Italy and/or not enough parts made in the USA.”

the trifecta of 922r compliance that i chose for my 11707 M4 (total about $350):

carrier comp 7 round mag tube replacement with follower ( 2x 922r compliance ) and spring
