AR 15 Stripped Upper and Lower Set: What You Need to Know

If you're in the market for a new AR 15 stripped upper and lower set, there are a few things you should know before making your purchase. The AR 15 is one of the most versatile firearms on the market today, but it's important to make sure you have all of the right components in order to get the most out of your weapon.

What is an AR 15 Stripped Upper and Lower Set?

An AR 15 stripped upper and lower set consists of two separate parts: the upper receiver and lower receiver. The upper receiver is where the barrel, bolt carrier group, charging handle, and other components are housed. The lower receiver contains essential parts such as trigger assembly group which includes hammer assembly trigger spring disconnector spring disconnector hammer pin trigger pivot pin safety selector magazine catch button magazine catch front pivot pin rear takedown detent buffer retainer springs.

When purchasing a stripped set, none of these parts are included – hence why it's called "stripped." Instead they will need to be purchased separately or taken from an existing build or rifle if available.

Benefits of Using an AR 15 Stripped Upper & Lower Set

One major benefit that comes with using a stripped upper & lower set versus buying them pre-built as complete receivers is that by building it yourself you have more control over what goes into your firearm which can result in better performance due to personal preferences for certain components (for instance triggers). Additionally constructing this yourself provides valuable insight into how this firearm operates which may not otherwise be gained just through use alone.

Another benefit with going down this route is cost savings. While it may seem like buying everything piecemeal would add up quickly compared against getting fully assembled receivers back-to-back; but many times when purchasing individual pieces instead purchasing whole assembled units its price differential that really adds up quick! Given that some of the parts with a pre-built ensemble may not be entirely necessary based on your use case, you can ultimately save money on stuff you don't even need (and likely wouldn't have opted to add anyway).

Comparisons: Stripped Upper and Lower Set vs Ready Built Receivers

When comparing stripped upper and lower sets against fully built receivers there are pros and cons for both. Here is what to keep in mind:

Stripped Upper & Lower Sets:

  • Allows for more customization
  • Can be cheaper than purchasing complete receivers
  • Requires more assembly
  • More time-consuming

Pre-Built Complete Receivers:

  • Faster build times
  • Generally easier building process
  • No additional components or tools required beyond AR15 kits.

Tips for Building an AR 15 using a Stripped Upper & Lower Set

If this is your first time building an AR 15 from scratch, it's important to do some research beforehand. You should also have the proper tools handy, such as punches, a torque wrench set, pliers or tweezers if possible (not required). Be sure to follow instructions closely when assembling the stripped set – attention-to-detail will enable everything functions correctly upon firing testing.

It's also important not just focus solely on pricing; rather be sure that each piece included in build meets or exceeds minimum standards – especially crucial since these guns are subjected rigorous firing conditions! Don't skimp quality; otherwise performance reliability issues down line might crop up unexpectedly.


An AR 15 stripped upper & lower set provides gun enthusiasts with significantly greater flexibility over their firearms construction which can lead increased performance enhancements due personal taste preferences over certain components. Whether you're looking at cost savings versus buying fully assembled units outright or merely wanting maximum control of every single aspect of your firearm combining one these sets with corresponding pieces chosen individually might make all difference between something great someone mediocre — hence why many gun enthusiasts choose this route. Ultimately, it's essential to know the benefits and pitfalls when building your own AR-15 so that you can make informed decisions about what will work best for you.


What is an AR-15 Stripped Upper and Lower Set?

An AR-15 stripped upper and lower set refers to the two main components of an AR-15 rifle that are required for it to function – the upper receiver and the lower receiver. The "stripped" designation means that these components do not come with any other parts installed, such as the barrel or trigger assembly.

The upper receiver contains vital parts such as the bolt carrier group, charging handle, ejection port cover, forward assist button and barrel nut threads. It also houses a rail system which allows for attachment of accessories like optics.

The lower receiver consists of several key components including trigger assembly group (trigger housing), safety selector lever(s), magwell (magazine well) where magazine is inserted.

When purchasing a stripped upper and lower set you will need to purchase additional parts separately in order to complete your custom build.

Why would I choose a stripped upper and lower set instead of purchasing a complete rifle?

Purchasing separate stripped sets allows one more control over customization options when building their own firearm. This can be beneficial if you have specific requirements in mind or simply prefer certain features on your weapon that may not be available on fully assembled rifles.

Buying separates can work out cheaper than buying pre-assembled firearms since many manufacturers charge extra fees for labor costs associated with assembling guns.

Can I assemble my own rifle using an AR-15 Stripped Upper & Lower Set?

Yes! Assembling your own firearm using this type of kit requires some mechanical aptitude but doesn't require prior experience beyond basic knowledge about firearms mechanics (that's why we have YouTube). With little effort anyone who wants build their own custom gun from scratch can do so by following step-by-step instructions from builders manuals or online tutorials.

You will need some specialized tools like punches pin pushers wrenches etc but nothing too crazy expensive

However, it's important to note that some states have specific laws regarding the purchase of certain firearm parts and accessories so be sure to check if they apply in your region.

Also, any builder attempting to construct a firearm using a stripped upper & lower set should comply with all federal regulations pertaining to DIY firearms manufacture including completion of form1/Form4 where required.

What materials are typically used for AR-15 Stripped Upper and Lower Sets?

Typically these components are made from high quality aluminum alloy; 7075-T6 is considered industry standard. 6061-T6 is also commonly used but not quite as strong as its counterpart which can cause problems down the line like cracking or becoming fatigued faster than expected due its brittle nature .

Some manufacturers produce upper/lower sets constructed from billet aluminum (machined blocks) which although more expensive provide greater rigidity over their forged counterparts.
