To help clarify any questions you may have about these tiny but mighty tools, we’ve compiled a list of frequently asked questions below:

Q: What exactly are AR Barrel Nut Shims?
AR Barrel Nut Shims are thin pieces of metal (usually made from stainless steel) that help adjust the timing of your barrel nut in relation to your receiver threads for proper bolt carrier group (BCG) cycling. These shims can range anywhere from 0.001” thick up to 0.010”.

Q: How do I know if I need to use them?
If you’re experiencing issues getting your BCG to cycle properly after installing a new barrel or changing out parts within your upper receiver assembly like triggers or rail systems; then chances are good that you would benefit from adding some barrel nut shimming.

Q: Are they difficult to install?
Not at all! Installing shimmed barrels isn’t much different than installing non-shimmed ones once you understand everything involved – which primarily consists of carefully tightening down by hand because over-tightening may cause more problems than it solves!

This is where having specific torque wrenches used in the industry come into play such as wheeler engineering FAT torque wrench specifically engineered for firearms shown below:


After attaching each shim layer using oil/lubricant, place the barrel nut itself over the shims and aligned torque wrench and match-up all indexing/mounting screws. Very slowly begin to tighten in increments of just a few ft/lbs each time, then double check alignment with index lines on gear.

Q: How many AR Barrel Nut Shims should I use?
The number of shims needed will vary depending on your specific rifle’s configuration as well as other parts that have been changed before. Experts recommend adding or subtracting one shim layer for every 3-5 degrees (or flats ) of movement required to fully align your barrel correctly – so be sure not to skimp!

Q: Are there any risks associated with using AR Barrel Nut Shims?
There are very little risks according to industry experts when installed properly without cutting corners like over-tightening or omitting layers entirely; however some users recommend checking BCG timing by putting thousands of rounds through before trusting completely since this practice may cause wear & tear sometimes resulting in misalignments which only could be diagnosed after extensive use/cycling.

Top 3 Benefits of Using AR Barrel Nut Shims in Your Rifle Build

If you’re an avid shooter, gunsmith or just someone who likes assembling firearms, then one component that should not go unnoticed is the AR barrel nut shims. Often overlooked and overshadowed by more popular parts such as triggers and handguards, they play a critical role in ensuring your rifle functions optimally.

So why are these tiny metal discs so important? Let’s take a closer look at the top three benefits of using AR barrel nut shims in your rifle build:

1. Corrects Misalignment Issues

AR rifles rely on precise alignment of their many components to function properly. The barrel nut plays a crucial role in this process; when torqued down it compresses the gas tube against the receiver extension creating a sturdy connection between upper and lower receivers.

However, due to manufacturing tolerances or wear over time there are cases where malalignments may occur leading to issues like poor accuracy, difficulty chambering rounds or cycling problems among others.

Fortunately, with an array of shim sizes available on the market today it’s simple matter of finding ones that fit snugly into position for any misaligned areas around the threads thereby correcting proper torque values which ensures correct functionality without added stress on sensitive internal mechanisms.

2. Prevents Over-torquing

Over-torque can be a major cause for concern while assembling your rifledue to its negative impact on system life span and reliability. Fires caused by over tightening have resulted from barrels splitting open after getting too hot under sustained fire during training exercises or prolonged hunting sessions eventually requiring costly repairs beyond regular maintenance routines recommended by manufacturers themselves! In other words: prevention definitely pays off.

AR Barrel Nut Shims acts as another barrier towards over-tightening any one part/component against each other – whether accidentally or purposely indulging increased twisting force- fitting perfectly underneath while making sure all portions remain equalised proportionally facilitating uniform pressure application instead putting excess stress upon individual contact spots potentially damaging or deforming critical sections of the rifle assembly.

So even if over-torquing does take place, most of these shims deform harmlessly to discharge applied stress limiting risks associated with potential warping or other related issues declining general system longevity.

3. Quietens The Build

Rifles are often used in demanding environments where every movement and sound could mean missing a target. Being able to operate quietly is essential for hunters and tactical shooters alike who might not always have the luxury of using a silencer/suppressor. Equipping your rifle build with AR Barrel Nut Shims helps minimize noise levels when shots are fired due to their ability to distribute shockwaves evenly thus reducing vibration at contact points resulting in quieter operation throughout its use as well as improving accuracy consistency during objective tasks like range practise/training events too!

In conclusion, incorporating AR barrel nut shims into any standard rifle assembly should be considered paramount by all gun enthusiasts, whether novice builders or experienced ones too respectively promising long lasting serviceability while simultaneously enhancing shooting accuracy without adding weight/compromise onto individual components whilst generally retarding failure modes affecting overall weapon handling ensuring smoother operations throughout routine firing needs giving full confidence regardless it’s intended purpose – gaming competitions, sport hunting expeditions or national defence services!

Enhance Your Accuracy with Properly Installed AR Barrel Nut Shims

When it comes to firearms, accuracy is key. No matter what type of shooting you do, whether it be competitive or recreational, the goal is always to hit your target with as much precision as possible. And one crucial component that can greatly affect accuracy is the barrel nut.

The barrel nut serves as a connecting point between the upper and lower receivers in an AR-type rifle, holding the barrel firmly in place. However, even slight misalignments or imperfect torque on this part can cause problems with accuracy downrange. That’s where properly installed barrel nut shims come into play.

Barrel nut shims are thin metal washers designed to sit between the receiver and barrel nut while tightening them together during assembly. These shims allow for minute adjustments in alignment and help create a more secure fit between all components involved.
