.300 AAC Blackout SBR

It mentioned a vice in the article. I kind of had a feeling you shouldn't swap barrels without a whole new upper receiver.

Question I have is it worth the extra $300 to get a full rifle or just save it? Can the two push out pins that mount/dismount the upper wear out with too much use?

My rear pin pushes out with a little pressure but the fwd pin near the breech is hard to push out. Is it ok to add a lil lubricant to the inside of that pin to make it slide out easier?

Personally, for the $300.00, I'd prefer to have the extra rifle.  However someone may have whatever reasons to just want the upper (like if he has a legal "off-paper" AR-15 and would rather just add to that platform).

Or, you can purchase the upper directly through Gunbroker, and not have to pay dealer fees or the 11% Firearms Excise Tax that applies to a complete rifle (that's $99.00 on a $900.00 gun).

But if you have your CCW Permit and have purchased previous firearms over-the-counter, then there is already a stack of background checks and ATF Form 4473's with your name on them.  What difference is one more going to make?

I suppose a guy could have bought a lower in a gun show or from a private seller without a background check. I always wondered if you buy 3 guns at once is it 3 separate checks in a row or one check for the total order that day?

There are some people who want to amass a collection without the ATF knowing by buying lowers or actions outside of a store and buy uppers or barrels through stores.

Personally I may look into a whole new rifle.

Whats your opinion to adding some lube to the fwd pin that holds the upper receiver?

Good point. Later on go to gun show and purchase a lower, trigger assembly, stock, and grip to make a complete rifle without the taxes and the 4473.

It's too late for me to be too paranoid about the Gubmunt.

But if someone wants to legally exercise caution and protect his privacy, so be it.

Nothing wrong with putting a little Break-Free or Tri-Flow or a spot of Rifle Grease on that pin.

They taught us that, if you wanted to destroy an M-16, the easiest way was to pull our the rear pin, leave the front pin in, and twist the Upper Receiver from the Lower, until you broke off the holes that the front takedown pin goes through.

You're going to have to fill out a 4473, if you get it from a dealer or manufacturer.  But you will save on the 11% taxes for sure.  The lower receiver is classified as the "Firearm", and the purchase of a Lower is a "Firearm Transfer".

I never twist the receivers. I use a screwdriver philips tip and tap the front pin out. The back one I use the plastic piece you see inserted into new gun actions and push palm down and it pushes out fine. I have CLP think of using that.

Yes, I know if it is FFL selling lowers at the show but not if it is a private seller that sets up a table. My father inlaw bought a 20 ga single shot once from a private seller at a show with only his ID.

Try the cap from a Bic Pen. Use the blunt end to tap out the head of the pin, and the pocket clip to finish pushing it out. It is plastic, and will not mar the finish.
