I know there are vast choices when it comes to triggers, but besides the trigger does it matter?
It depends on the brand of the lower receiver. Some brands, like Colt, are proprietary and require specific parts kits. Other brands, like AR-15, are more universal and will work with most lower receivers.
When purchasing a parts kit for a rifle build, it’s important to be aware of the brand of lower receiver that will be used. If the lower receiver is not specified, then it’s best to go with a universal kit that will work with most brands. There are also many quality aftermarket parts kits available, so it’s worth exploring those options as well.
There are numerous brands of AR-15 lower receivers on the market, and most (but not all) lower receiver part kits will work with them. However, it’s important to check the compatibility of the parts kit with the specific model of lower receiver that you have, as there can be minor differences in dimensions between different models.
If you’re not sure whether a particular lower receiver part kit is compatible with your rifle, it’s always best to consult the manufacturer or retailer to find out for sure. And if you do buy a part kit that’s not compatible with your rifle, there’s a good chance that some or all of the parts will not fit properly and could potentially damage your firearm.
As far as I know, most lower receiver part kits are designed to work with any brand of lower. However, there may be some compatibility issues depending on the specific kit you’re using. For example, if you’re using a Kit that’s designed for a DPMS Carbine, it might not fit properly on a Rock River Arms Lower Receiver. It just depends on the kit and the receiver. As far as I know, though, most kits should work with most brands of lower receivers.
It’s important to remember that the foundation of any good AR platform rifle starts with a quality lower receiver. Just as you wouldn’t put $500 tires on a Kia Rio, you don’t want to skimp on your lower receiver when building an AR.
Lower receivers are where registered serial numbers are located and where the hammer, trigger, and other critical fire control group components are housed. These components must be properly machined to very tight tolerances for the gun to function correctly and safely. Thus, it is important to make sure that your lower receiver is made by a reputable manufacturer that adheres to strict quality control standards.
There are three basic types of lower receivers that you will encounter when shopping for AR-15s: forged, billet, and polymer. Here’s a quick rundown on each type:
- Forged Lower Receivers
Forged lower receivers are made by taking a piece of aluminum and pounding or hammering it into shape. This is the same basic process that has been used to make gun parts for centuries. The advantage of forged receivers is that they are typically stronger than either billet or polymer receivers because the aluminum grain flow is more uniform throughout the part.
- Billet Lower Receivers
Billet lower receivers are made by taking a piece of aluminum and machining it to the correct shape. This is the same basic process that is used to make many other types of parts, including engine blocks and airplane wings. The advantage of billet receivers is that they can be more easily customized with unique designs than forged receivers.
- Polymer Lower Receivers
Polymer lower receivers are made by injection molding a piece of polymer plastic to the correct shape. This is the same basic process that is used to make many other types of parts, including car bumpers and computer keyboard keycaps. The advantage of polymer receivers is that they are typically lighter than either forged or billet receivers.
So, which type of receiver is best for you? That depends on your needs and preferences. All three types of receivers are strong and capable of delivering good performance. The decision ultimately comes down to a matter of personal preference.
If you’re looking for the strongest possible receiver, then forged is the way to go. If you’re looking for a receiver that can be easily customized with unique designs, then billet is the way to go. And if you’re looking for a receiver that is lighter-weight, then the polymer is the way to go.
No matter which type of receiver you choose, make sure that it is made by a reputable manufacturer who adheres to strict quality control standards. This will ensure that your receiver is strong and capable of delivering good performance.
