Upper Questions

[SFFRONTMAN]

Hows it goin folks! Well I have a question that the search function cannot seem to answer. For my first OLL build, I am going with a mm grip, A2 stock, and without the fun stuff i.e (no forward pistol grip, flash hider, grenade launcher blah blah) to make my gun CA detachable legal. I like the look of the m4 style uppers, but I want to ditch the flash hider and if possible put on a fake can or a muzzle break. My questions are would a 16 in m4 upper that comes with a flash suppressor..

1. Is the flash hider removable
2. Would I have to attach a muzzle break permanently on the barrel to be legal
3. Is a fake can legal in CA
4. Would you recommend gunsmith work or is it easy to do myself ( attach)
5. Or would just a thread cap without the flash suppressor be legal

Any and all answers would be greatly appreciated!

1, Yes, it threads right off
2. Nope, as long as the barrel is at least 16" long
3. Yes
4. DYI
5. Yes also

Sweet, and one more question. Are the 16in m4 uppers that a lot of companies sell (like stag, cmmg, lmt) such as this
have a 16 inch barrel without the suppressor?

order one and tell them to take off the flash hider for you much easier

[Lateralus]

none of the ones ive bought have come w/ just the bare threaded barrel, but you can either ask them to take it off, which they prolly will, or do it yourself. Like the other guy said, as long as the barrel itself is 16", it isnt permanently attached and should twist right off

I bought a 16" upper and a Branson Compensator that looks just like the A2 flashhider from Del-Ton on the same order. I asked, and they mounted it on the barrel before shipping it for no additional charge. No muss, no fuss and it looks like the real deal. Good prices, seems to be good product, I have no complaints.
I believe a number of vendors would do likewise. If you are dealing with a distributor, then there may be problems with messing with a brand new upper outside of the factory causing warranty issues.

There's no legal issue with getting the upper and attached flash hider, removing it (and adding a brake, if desired), then putting it on your lower.

I was looking at the stag arms uppers halves Pre-Ban on their web site and they say that they are available in Post-Ban for CA and other states.

What does stag do to these pre-ban uppers to make them post-ban and CA legal exactly. I'm new to this and just trying to understand it completely.

The Stag Uppers are already "CA Legal" in the default configuration. It's when you attach it to a lower that you have to be careful. If attaching to a Bullet Button or other mag-locked lower, they are fine. If attaching to a featureless or MonsterMan equipped lower, you must remove the flash-hider.

I don't think I worded it correctly. Is the standard 16in m4 barrel without the flash suppressor 16in by itself, or does it add the length to make it 16in overal

Yes.

[SFFRONTMAN]

Yes to what? Is the 16" m4 barrel without the standard suppressor still 16?"

They are 16" without the flash hider.

[aplinker]

Manufacturers list lengths by barrel length and do not include the length of the flash hider or brake. The only time they do otherwise will be clear -- they will say it's a 14.5" barrel with a permanently attached FH or brake to make it a 16" OAL. They know better than to make this confusing.

Most factory 16" barrels will actually measure between 16 1/8" and 16 1/4" long.
