Pistol Receiver Extension Buffer Tube
The National Firearms Act of 1934 is a tricky thing. If you have a rifle with a 16-inch barrel, then you are in full compliance with the #NFA . If you have a #rifle that has a 15.9-inch barrel, then you are guilty of a crime. The #ATF would like you to pay a fee of $200 for a tax stamp, provide fingerprints, mug shots, and wait months and months for the honor of owning a short barreled rifle.
There is a way to experience the thrill of owning an SBR without having to pay the ATF a bribe to exercise your rights as an American. People are buying AR and AK pistols and adding stabilizing braces. Since these braces are technically not stocks, they do not fall under the NFA. The barrels on these guns do not have any length restrictions on them since they are not rifles. A while ago I did a review on a brace made by SB Tactical for my CZ Scorpion EVO3 pistol. I was impressed with the SBTEVO brace's workmanship. It was just as good as a standard stock without going through the hassle of jumping through the hoops of the NFA. In fact, it is still my bedside gun. When SB Tactical asked me if I wanted to try out their new SB-Mini brace and their SB STDT AR Pistol Receiver Extension buffer tube I had just the thing to test the brace to its limits.
I also recently did a review on a 10.5-inch Radical Firearms complete AR upper receiver chambered in .458 SOCOM. I installed it on my complete Anderson pistol lower receiver and headed out to the range. It was a blast to shoot, but it did kick like a mule. If the SB-Mini could tame this beast, then it could handle almost anything. When the SB-Mini brace and the SB STDT Pistol Receiver Extension buffer tube arrived at my door, I couldn't wait to get them on my Anderson pistol lower. I removed the old buffer tube and installed the new SB Tactical buffer tube. The the new buffer tube measured 8.3 inches in overall length. The SB STDT added about one additional inch over the Anderson pistol buffer tube that was installed previously on the lower receiver.
SB Tactical made the SB STDT out of airplane grade 7075-T6 aluminum. SB Tactical then finished the buffer tube with a type III anodization process. They designed the SB STDT to minimize the rotation and the slippage of their braces. This buffer tube is a must when buying an SB Tactical brace. I picked up the SB-Mini brace to put it on the buffer tube. The one thing I noticed about brace is that it is very light. SB Tactical made the brace to weigh only four ounces. It can also fit on any tube with a diameter from 1.2 inches to 1.25 inches. The SB STDT that I was using for testing is a 1.25-inch diameter tube.
