AR 308 AR-15 AR-10 Roll Pin Tools

308AR AR15 AR-10 Roll Pin Tools – One of my pet peeves from folks who assemble their own AR15 AR-10 308 AR rifles is the sloppy installation of the various roll pins the rifles require. In all fairness there are a few roll pins that present a challenge to the inexperienced and experienced alike. The BOLT CATCH ROLL PIN comes to mind as does the FORWARD ASSIST ROLL PIN. The BOLT CATCH ROLL PIN is positioned quite close to the body of the LOWER RECEIVER and requires a ROLL PIN PUNCH to have a flat side to properly install.

I have searched the internet shooting forums and websites as well polled user of my own forums for a better way to install roll pins. In that search I found some creative approaches but nothing that worked any better than my own approach of taping a ROLL PIN to a ROLL PIN PUNCH. Well that was then this is now. Brownells offers a ROLL PIN STARTER SET they refer to as ROLL PIN HOLDERS. The pins are available individually or as a set for just under $50. I opted for the set.

BROWNELLS 308 AR AR-15 AR-10  ROLL PIN HOLDER OPERATION

The roll pin holders are genius.  As seen in the image above the ROLL PIN HOLDERS are simply a punch that has a hollow tip the diameter of a given roll pin.  Place the ROLL PIN in the correct ROLL PIN PUNCH HOLDER and with a plastic faced or brass hammer carefully tap in the ROLL PIN.  To prevent damage to the the WEAPON stop hammering before the ROLL PIN HOLDER contacts the part that accepting the ROLL PIN. At that point switch to a regular ROLL PIN PUNCH, the type with a half round nose and finish driving the ROLL PIN flush.

NOTES ON ROLL PIN HOLDER USE

  1. Cover any part of your weapon with masking tape followed by duct tape in an area that could be damaged from ROLL PIN INSTALLATION. The masking tape serves as a great protector for your weapon. The underlying masking tape makes duct tape removal a simple process.
  2. Grease – I like to apply a small amount of grease in the ROLL PIN HOLE to help with proper installation. I also add a small amount of grease to the inside of the ROLL PIN HOLDER to help prevent the ROLL PIN from falling out and getting lost should I have a brain lapse.
  3. For finishing the BOLT CATCH ROLL PIN INSTALLATION I suggest the BOLT CATCH PIN PUNCH from Brownells. It is almost entirely flat on one side making installing the BOLT CATCH ROLL PIN the rest of the way a breeze.

Hollow-Ended “Starter” Punches For Roll Pins

The Brownells Roll Pin Holder Set holds roll pins perfectly aligned for starting correctly. Especially good on the tiny, tough-to-grab ones, or those in tight places. 1/16″ is notched to clear M16/AR-15 rear sight. 3.5mm excellent for holding the pin that retains the breech block on Sig handguns. Finish driving with roll pin punch. O/A in chart means “Overall”. Available individually or as a set of 5.

MDT AR-10 PRS Adjustable Butt Plate

Recently at one of our other sites MODULARRIFLE.COM we retrofitted a Remington 700 BDL .308 with a Modular Driven Technologies MDT TAC21 Chassis. While exploring the MDT website I happened across the AR-10 PRS ADJUSTABLE BUTTPLATE (I added the term AR-10 for sake of this sites search engine presence). Up until this point I was only aware of the JP Rifles version. Installing an adjustable butt plate on a MAGPUL PRS will take an already great stock to the “be all it can be level” by allowing the shooter to dial in a perfect fit. I will be getting two.

The MDT AR-10 PRS Adjustable Butt Plate  is three-way adjustable for drop pitch and offset as well as length of pull. It further enhances the MAGPUL PRS® stock by adding the adjustability and the comfort of a soft rubber recoil pad. This is a complete module. It replaces the existing MAGPUL PRS® recoil pad, mechanism and all.

MDT AR-10 PRS Adjustable Butt Plate Features:

  • Allows for PRS stocks to be perfectly fit to your position and/or clothing
  • Adjustable vertically and for cant/rotation
  • PRS butt plate retains the LOP adjustment that comes standard with PRS stocks
  • Includes soft, rubber, recoil pad
  • Adjustments are easily accessed through the rear of the recoil pad
  • Over 3 inches of vertical adjustment
  • Easily replace existing PRS hardware
  • Aluminum construction with matte black anodizing and steel hardware with a matte black finish

It can be used with standard bolt carrier groups including: full auto, semi auto, 5.56 to .308.

The Law Tactical AR Folding Stock Adapter GEN 3  was designed for low profile transport of AR rifles in non-permissive environments. The adapter is ideal for any situation that requires a smaller profile weapon for transport and storage. Simple one-button release folds the stock. To engage, just unfold and fire. The stock automatically locks into place, requiring no fine motor skills.

Designed, built and assembled in the USA from CNC machined, 4140 steel.

The adapter does not affect gun function when unfolded in the standard fire position. The rear portion of the adapter is built to the same specifications as a standard receiver to ensure maximum compatibility. An integrated single point sling attachment point is included.

There are a couple simple reasons to utilize a Nickel Boron 308 AR Bolt Carrier Group in your 308AR and AR-10 rifles. The Nickel Boron Coating by FailZero is super slippery this means the bolt carrier group can operate with much less lubricant, the bolt carrier group will be easier to clean and the coating should allow the bolt carrier group to outlast the weapon under normal operating conditions. Less wear will also occur in the upper receiver. The finish also looks pretty slick.

Drop-in bolt and carrier group has a self-lubricating surface that eliminates the need to apply oil or grease that can attract dirt, dust, unburned powder, and carbon and lead to cycling failures. Proprietary EXO-treated Nickel Boron finish produces an exceptionally hard surface that’s 40% more wear resistant than chrome plating, with an ultra-low friction coefficient. Surface is actually harder than the substrate underneath and will not peel, flake, gall, or rub off. EXO-treated Nickel Boron finish bolt/carrier groups have been tested to function reliably without additional lubrication up to 50,000 rounds. Reduced friction also means less heat generated by metal-on-metal contact, so the gun runs cooler and parts last longer. Easy to clean, too—fouling brushes right off. Before treatment, parts are shot peened for surface uniformity and magnetic particle inspected to make sure there are no hidden flaws. Gas key is hardened to USGI specs, chrome lined to resist erosion, and comes already staked to the carrier.
