Bullet button question

[rideordie]

Sorry if this has been covered but I tried the search function and I didn't come up with anything.

I did a ffl transfer from out of state for a new frontier armory polymer lower. The lower was shipped to my ffl with a regular mag release and lpk installed.

I know the law in regards to featureless builds and the lower already has a pistol grip so do I legally need to put a bullet button on it right now? Is it a felony to have a built lower with no bullet button?

Thanks in advance for the help.

No bullet button needed since a lower is not a center fire rifle. You only need to install one if you're going to put a center fire upper on it and you're not going featureless.

Okay, perfect. That's what I was thinking but I wasn't positive. Thanks for the info.

However, not all FFLs understand the law. Some may require a mag lock on it period. Check with your FFL to make sure.

Ya i picked up the lower today from San Jose Gun Trader. They are great. But there are a few local ffl that gave me a hard time about receiving an out of state lower.
