Step-by-Step Assembly Instructions

With your tools ready on hand and your parts list complete let's move on to assembling an AR-15:

Step One: Assembling The Lower

The lower receiver is made up of several small components that must be assembled correctly for everything to function properly. Begin by installing the magazine catch button (and spring if applicable), then attach it to the receiver using a roll pin punch.

Next up is installing the bolt catch assembly – slide it into place from inside ofthe left side until you can see both pins protruding outwards; use pliers as needed when pushing these through holes before securing with another roll pin punch.

Now install trigger group including hammer/disconnector springs whose coil end points toward its respective part then push down lightly onto plunger while aligning with slot in housing so that its tang fits under one leg situated at backside where two pins hold this whole setup tightly together providing stable platform around which rest any other component present on lower half part like safety selector lever detent/spring etc., Lastly fit stock "buffer" tube along with castle nut over thread ensuring proper alignment between them before tightening snugly using Armorers wrench.

Step Two: Installing the Buffer Tube and Stock

With your lower receiver fully assembled, it's time to move on to installing the buffer tube assembly. Start by threading the buffer tube into the back of the lower receiver until it's snug, then attach a castle nut onto it and tighten with an armorers wrench.

Next up is attaching your preferred stock to this assembly. Depending on what type of stock you've chosen there may be additional steps required – for example if using a collapsible buttstock you'll need to push down button allowing rod inside spring assembly come loose from its slot thus enabling adjustment via lever present at one end while holding other side firmly against shoulder area where cheek weld located.

Step Three: Assembling The Upper Receiver

Moving on to assembling upper receiver section now which includes barrel/gas block/tube/muzzle brake/flash hider handguard/rail system/M4E1 Enhanced Upper Receiver etc.,

Begin by installing forward assist button; slide into designated slot in uppermost part until protruding pin aligns properly from outside surface before screwing retaining clip plate over top securely with torque wrench helps ensure correct pressure applied so these components stay together during use.

Now fit barrel onto extension tube (making sure gas port holes line up between two parts), insert gas block above bottom-third position along lengthwise channel found underside then secure both using pins/punches as needed followed by threading muzzle brake/flash hider (if desired) over threads located at front end before securing everything else including handguard/rail system M4'E1 Enhanced Upper Receiver.

Conclusion
