There are two main grades of aluminum used for AR parts, and These numbers are used to grade and specify what type of aluminum alloy manufacturers are working with. These numbers measure the temper placed on the aluminum, meaning how metallurgists heat treat the metal to give it different properties other than what is found in the base alloy. The main differences are aesthetic; forged lowers from any company will match dimensionally, both internally and externally.
The vast majority of forged lowers are made to the latest military specifications. Billet lowers allow more artistic leeway with manufacturers. AR lowers come with clean lines, straighter edges, and an integrated, enlarged trigger guard. Durability might be the most hotly debated part of the forged lower vs. General consensus tends to be that due to the nature of the forging process that forged lowers are technically more durable.
The pressure applied by the hammering of forging compresses the aluminum and makes the metal grain run in a homogenous direction; both good things for rigidity and durability. Billet lowers do not have those hammer-hardened characteristics, but with the use of high quality grade aluminum in this day and age any concerns about durability are largely unnecessary. It then ends up, as most things AR will, as a personal preference choice from the end user.
There are many things to think about when purchasing an AWC AR lower receiver, hopefully this brief breakdown of the differences between forged and billet AR receivers can help you make a more informed decision. The beveling on the magwell is definitely better on the palmetto.
Finish seems about the same to me. I was pretty impressed. I am not sure about buffer tube material however I have heard its not milspec.
It has held up fine, however. They are as good as any of the other lowers I have and I have more money to go to other things. The Andersons seemed to have either tight takedown pin holes or were slightly "off" in one way or another. The threaded hole for the grip screws weren't threaded deep enough for the screws supplied. All the other brands were GTG with no problems during assembly.
Because Mega lowers are best. Stag and my preban pwa are very well in spec There's a thread here that explains the difference.
If I were to have one, LMT. I would like to own a colt one day. But the money for a colt preban with politically correct FCG pin holes and take down down pins and sear blocks are a huge turn off. Sear blocks can be cut out. One day. Next will be a bushy preban And SBR it. Quoted: Because Mega lowers are best.
But not in commie CT. Quoted: For a long time they were. They have actual competition now. Quoted: Quoted: Because Mega lowers are best. If you go budget on the lower just make sure you buy a quality LPK to finish it. You should be g2g. In my personal experience Anderson lowers have been g2g.
Sometimes they might take some working in like the takedown pins being a little tight or something Quoted: A truly ambidexterous lower would be a difference. Quoted: I've had quite a few different lower, and the ones that cost more, have been nicer. Aero will also sell match sets if you buy direct from them.
Quoted: As truly ambidextrous as it gets. Quoted: Quoted: A truly ambidexterous lower would be a difference. Quoted: So it has a right sided bolt catch, or is it only a bolt release? I would love to know what else out there has the ambi bolt catch. Quoted: Quoted: Quoted: A truly ambidexterous lower would be a difference. So is all that bad of an alloy for a lower? I have a Quentin Defense Billet here sitting on my table I am wondering what to do with in terms of my next build.
Consequently, many shooters prefer the AR over the AR due to its smaller size and its lighter weight as well as the lack of recoil generated by its significantly smaller cartridge. Thus, the AR is most often chosen for recreational shooting aka plinking , competition action shooting, medium sized game hunting, and home defense.
However, the AR is more often the choice of large game hunters and long range target shooters due the fact that it fires a significantly larger, more powerful, cartridge with a larger diameter bullet than the AR does. So, regardless of your intended purpose, if the standard 5.
Speaking of standard cartridges, what is the difference between the standard AR cartridge and the standard AR cartridge? Of course, when we refer to standard cartridges for the AR and the AR, we are referring to the standard NATO military cartridges which consist of two center fire, bottle neck, rifle cartridges which measure 7. In addition to their vastly different case lengths and case capacities, the two cartridges also have drastically different muzzle velocities.
For instance, the AR, which is designed to fire the 7. However, despite the significantly faster muzzle velocity of the AR round, the AR round produces far more kinetic energy. Thus, although the AR does produce noticeably more recoil than the AR, it also produces significantly more muzzle velocity and more kinetic energy and thus, the AR is capable of shooting over longer ranges, penetrating harder targets, and harvesting large game species than the AR is. So, as you can see, the AR and the AR both have significant differences that translate to significant advantages and disadvantages over the other which, in turn, tend to dictate which one a shooter chooses depending on their intended purpose.
