AR-15 Buyer’s Guide to Not Getting Ripped Off
Here is a step by step list of what we believe are the most important parts to check when looking into purchasing an AR-15. There are tons of different things you can or would want to check when getting a new weapon so please let us know what you think we should add to the list in the comments section below.
1. Safety Check
- Obviously, this one cannot fire as it has already been disassembled but be sure to check that your safety is on first before proceeding.
- Waterproof case comes with precut foam to hold AR-15 or AR-10 Rifle, Shotgun, and Pistol
- Also holds extra magazines, optics, gun attachments, & various accessories. Does not accommodate side attachments.
- 2 moisture removing silica gel canisters & waterproof accessory box & knife are included
2. Check the Barrel
- Check the front sight post and just run a line all the way down the barrel to make sure that it’s straight.
- Check the ears on the front sight post for any inward bends. This is important because these ears allow your eyes to naturally align when looking down sights.
- Last make sure the front sight is adjustable.
- 550 paracord rifle slings: 48.3''-61.2'', long adjustable rang meets different occasions
- Gun slings'hook: hook shape is particularly for quickly attaching and detaching, solid and durable metal is for safe and durable using, plus, universal size fits most of sling swivels
- The 2 points rifle slings are mainly made of high-strength polyester and polypropylene, to build a durable 550 para-cord and tactical gears, an emergency rope to help you in pinch
3. Upper Receiver and Barrel
- Check the upper receiver and barrel – Checking for serviceability
- Grab the upper receiver and six inch barrel portion and twist it to make sure it’s a solid piece
4. Gas Tube
- Check the gas tube
- Gas tube is only secured to the weapon by a pin on the front sight base
- The tube will wiggle because its only secure by the pin at the base
- Pull the gas tube back and forth to make sure it doesn’t come out and is well secured
- LOOKS GREAT ON YOUR BENCH/TABLE/COUNTER, SIZE LARGE 36 in x 12 in. Essential accessory for ar15 gunsmithing, repair and maintenance
- PREMIUM QUALITY MATERIAL - strong, sturdy, thick, durable and high build quality. Portable, rolls up good when you take it to shooting range
- PROTECTION FROM SCRATCHES AND DAMAGE - protection from scratches/damage to your weapon, but also protects the surface (table/counter tops) you're working on
5. Upper Receiver
- Check the upper receiver
- Look inside for a uniform shape
- Look to see that it is not bent or oval shaped but a nice round shape – this means that it has good contact with the gas key which helps it function correctly
6. Hand Guards
- Check the hand guards
- Check for cracks on both the ends of the hand guards
- If any of the tabs that secure the hand guard break off and you’re out shooting you’re in for a bad time. No one wants to touch a hot barrel
- Easy Peel and Stick Application. Slap is Pre-Cut.
- Our Premium US Made Slaps Offer Superior UV Protection, Chemical Resistance, Protection from Scuffs and Scrapes and are Completely Waterproof. Durable Hi-Vinyl Material.
- Non-Reflective Matte Finish & No Interference.
7. Bolt Carrier Group – Bolt Carrier
- Check the Bolt Carrier Group
- Look for irregular wear patterns along the guide rails
- You will see a little on the front and back of the bolt carrier but that is normal
- If you see sloping angles or crazy wear on the rear portion you know its bad
- Looks for cracks and pitting throughout
8. The Gas Key
- Check the stakes on the gas key and then wiggle the gas key
- If it wiggles you will need to send the whole bolt carrier to a gunsmith and get it re-staked
- WARNING – You CAN re-stake it yourself. The problem here is if you mess up, because you don’t know what you’re doing, you run the risk of the gas key breaking off while you’re firing leaving you with a locked up AR-15
- Magnification power: 4x ,Objective lens: 32mm, Field of view(feet/100 yards): 36.6, Length(inches): 5.5
- High performance optical scope with fiber optic sight for quick and accurate acquisition
- Crisp image for accurate shooting. With the green multi-layer coated lenses, the tactical compact scope can shoot target fast and precisely with high light transmission and resolution
9. Check the Bolt
- Check to see that you have smooth and fluid motion of the bolt inside the body
- You should be able to push it in and out nice and smooth
- If checking a gun from a lower end manufacturer it may be sticky for a while
10. Break Down the Bolt Carrier
- Check the rings inside the bolt carrier
- Make sure they aren’t touching or overlapping – these work the same as a piston engine
- This is what stops gas from escaping. If they are out of place you could lose pressure and hurt cycling
- FITS ANY SIZE FLAG; EASY TO USE; Just Attach the Two Poles Together, Add It Into Your Hitch Receiver, Put In the Locking Pins and Attach Your Full Sized Flag. 3 x 5 Flag = No Problem. 4 x 6 = No problem. Other sizes...You guessed it. No problem.

- STREET LEGAL PORTABLE 6 FOOT FLAGPOLE Holder For Your Truck, SUV, or RV; Be a Real Fan and Represent Your Country or Your Team at the Tailgate with Style.
11. Lower Receiver – Stock is well connected to the lower receiver
- Check that there is not a huge amount of wiggle going on
12. Make sure you Buffer Assembly Cycles Freely
- Make sure that your buffer assembly cycles freely
- Push it in and out
BONUS TIP – Not usually checked on AR-15’s
1. Make sure you have the safety on
- Focus on the hammer and when you pull the trigger back while the safety is still on the hammer will dip down very slightly
- This is a sign of a properly adjusted trigger on an AR-15
- This means there is negative angle on the trigger face which is good
- Put the gun into fire and brace the hammer with your thumb
- Pull the trigger and keep the hammer from hitting the lower receiver.
- You don’t want to drop the hammer and dent your lower receiver
- Keep the trigger pulled and pull the hammer all the way back until it clicks back in place
- Let go of the trigger and listen for it to click – this is the reset
- If it doesn’t click and reset then you need to have the trigger assembly looked at by a gunsmith
AR-15’s are not meant to be loose guns. The only thing that is okay to be loose is the fit between the upper and lower receiver. I am not saying there should be a huge gap between them, like the size of a pen tip, this would mean the rifle is mismatched. If it does fit a piece of paper, I wouldn’t worry about it.
