The only downsides are the increased cost of ammo, reduced range, and slightly heightened recoil impulse. 300 Blackout with a quality suppressor, you can get into the 120 dB range, making it one of the quietest cartridges available to the AR platform. You can even use the same magazines as 5.56. 300 Blackout, you can use many of the same parts and components as standard 5.56x45 pistols. 300 Blackout include parts compatibility and suppressed noise ratings. 300 Blackout, you can even have a 5” barrel without over-gassing or reliability issues. With a heavier bullet, you preserve your terminal ballistics at lower velocities, so you can get adequate performance from ultra-short barrels. This means 300 Blackout has a shorter effective range, but it delivers more mass on target. 300 AAC Blackout is a low-velocity, high-weight cartridge optimized for AR15s with short barrels. You’re better off running a plain handguard than risking it with a foregrip that sits on the border of legal. The ATF has previously stated that angled foregrips and handstops are fine, but their views can change quickly. That said, if you want to play it safe, DO NOT USE A VERTICAL GRIP ON A PISTOL. This is because the legal definition of pistol considers concealability, which is partially defined by overall length. For example, if your pistol’s overall length measures over 26” (not counting muzzle device), it may be able to have a vertical grip because it classifies as a ‘firearm’ instead of a ‘pistol’. Federal law has some strange intricacies as well. That said, these laws can be somewhat complex, so it’s important that you do extensive research both on federal law and your local/state laws to confirm a pistol’s legality. They adhere to the same laws as any other pistol. In most states, AR15 pistols are perfectly legal. Those wishing to obtain more information about the construction of an AR 15 Pistol should contact the Bureau of Alcohol, Tobacco, Firearms and Explosives directly.

Even though a tiny piece on the AR is expensive, it is just as important to be well made as the next piece. The final piece that I decided to cheap on was an epic failure.
It's ironic because every piece of my AR consists high quality, well known, name brand equipment. Every one of them worked as if they were machined for my Aero Precision AR's. After receiving them I installed them in half the time because the Norgon one's came with a real cool and simple installation tool. I ordered 5 Norgon Ambi's and returned the Botach knock offs. I contacted Norgon and to my surprise I received a lengthy personal email. Suddenly, all the reviews that I did on the Ambi Catch's started running through my head and there was one common theme, the Norgon Ambi was hands down the only one that I saw worked every time. I even tried the other Botach Ambi that I ordered just to be sure it wasn't just a fluke, same results. I tried the same Botach Ambi on my other AP lower and no surprise, the same thing happened.
I ended up gently beating the shit out of it with a plastic tip hammer before it gave up and released the magazine. I couldn't press the button in and the magazine was stuck up in the AR like it was a part of the rifle. I inserted the magazine and went to release it by using the Botach Ambi mag release and nothing happened, I mean nothing. After I received them I installed one on my go to Aero Precision AR. It said made in the USA and looked just like the original Ambi Catch, so I purchased a few of them. After I did some looking around, I found the Botach version of the Ambi Catch. I looked at the Norgon Ambi Catch first, but thought the price was a bit steep. In my quest to set up an AR rig that is a balance of ambidextrous but not have a bunch of weird crap on it, I have decided to put an Ambi mag release on my rifle(s). For starters, I am just a random non-tactical dude that likes to shoot cool guns and happens to be lucky enough to be a left handed rifle shooter.
