Do it yourself AR-15 build is a great way to get a inexpensive / cheap AR-15 without sacrificing quality.

Included are instruction for removing the standard trigger guard and replacing it with the Magpul enhanced trigger guard.

This build uses a Spikes Tactical Lower Parts Kit, a Magpul Enhanced Tripper Guard, and a Magpul MOE Grip Plus (Grip+). The Spikes trigger and hammer are much better than the DPMS one my last build used. The Magpul enhanced trigger guard it was cool and comfortable. And, aftermarket grips are a great upgrade. I have used Ergo Grips in the past, this one uses a Magpul MOE Grip, which is a winner.

The least expensive way to get a new AR-15 is to buy a stripped lower receiver and a rifle kit. The rifle kit will include a lower parts kit, a stock assembly, and an assembled and test fired upper. Install the parts in the lower parts kit and the stock, use the takedown pins to attach the upper, and you have a $600 AR-15.

I am almost a minimalist when it comes to tools. There are only a few things you “need”. One guy posted on ar15.com that he used a nail with the tip filed flat to assemble his AR, which is way cheaper than I want to go.

My required tool list is surprisingly short. Many are readily available on amazon.com. You need:
-Safety Glasses (no, really)
-Hammer
-Punch Set (A regular drive punch set will work, but there is a higher risk of slipping off the pin and gouging the receiver compared to a set of roll pin punches, which is preferred. A roll pin starter set is a luxury but fun if you like to collect tools.)
-Masking or Painter’s tape, to cover parts of the receiver as a hedge against a slipped punch.
-Large flat head screw driver, or Allen set, to screw in the grip. You might get the “” or something similar, which is fine for light duty and great for guns.
-A pivot pin installation tool (for the front takedown pin). You get, maybe, get by without, but it is worth the couple of dollars to spend on this.
-A vice block is probably required for a carbine stock install so you don’t put a lot of strain on the grip (remember, small steel screw in an aluminum receiver). I haven’t used one outside of a stock install.
-A piece of wood to support the receiver (trigger guard install).

You can get many of the tool from amazon.com at a reasonable price.

Take your time with the assembly and go slow. You can get through it.

Not specifically, but in general, these are good examples of what tools you might need. You don’t need “great” tools, “good enough” will do for a lower build.
