AR Sleds

Bob Hahin has designed the Original Bob Sled(OBS) as a single round loading device for AR-15 and similar pattern rifles. A single round loading device is a magazine that holds no rounds. Its purpose is to allow the loading and firing of a single round at a time during competition, at the benchrest, or out varmint shooting. The OBS is CNC machined from a single piece of black Delrin®.

Here is how it works

The OBS is inserted instead of a magazine. When the bolt is opened, the built-in plunger trips the bolt catch and holds the bolt open. A single round is then placed in the ejection port and allowed to rest in the channel of the OBS. The bolt release button is pressed and the single round is loaded. When that round is fired, the action cycles normally and the OBS plunger trips the bolt catch lever to hold the bolt open. This provides a very smooth operation for the slow fire that is required during High Power Rifle Competition, Benchrest Competition, load development, and varmint or long range shooting where the length of the bullet may exceed maximum magazine length.

General Advantages:

  • Operates and feels like a standard 20 or 10 round magazine.
  • The loading channel perfectly aligns the round to enter the chamber.
  • The plunger automatically activates the bolt stop and holds the bolt open ready for the next round to be loaded.
  • The loading lip on the left side is chamfered to prevent a round from lodging on top of it.
  • Long rounds, which will not fit in a standard magazine, can be single loaded.
  • Delrin® is unbreakable and does not scratch, mar or dent metal parts.
  • Excellent for testing new handloads.
  • Extra safety when teaching new shooters.
  • Designed and Made in the USA on CNC Milling Machinery!

Competition Advantages:

  • Keeps your AR-15 straight and level while single loading a round in slow-fire.
  • No need to destroy a "good" magazine to make a poor single loading magazine.
  • Excellent for standing and prone slow-fire competition!!!
  • No need to "break position" when locked down in prone to load a round.
 

AR Models:

The OBS comes in three models that fit the AR-15 lower receiver, and two that fit the larger .308 receivers. The first two are the AR-15 Match Rifle(left below) and AR-15 Service Rifle(right below). The AR-15 Match Sled is the same size as a standard 10 round magazine and meets the Match Rifle rules for High Power Rifle Competition. It also works well when load developing or shooting off the bench. The AR-15 Service Rifle Sled is exactly the same size as a standard 20 round magazine and meets the Service Rifle and CMP rules for High Power Competition.

AR-15 OBS



The third model that fits the AR-15 receiver is the 6mm-15 sled. This model is designed for AR-15 pattern rifles that are chambered in the fatter 6mm cartridges such as the 6mmAR, 6 PPC, .224AR, 6mmAR Turbo, 6.8 SPC, 6.5 Grendel and more. The 6mm-AR is the same size as a 10rd magazine and is offered in Match Rifle length only.

6mm OBS



OBS has extended our line of AR sleds to include the two most popular .308 caliber AR pattern rifles, the AR-10 and the DPMS SR/LR308. The AR-10 sled fits only ArmaLite pattern AR-10 rifles and is offered in match rifle length only.

The SR/LR308 sled fits Stoner SR-25, DPMS LR .308 and Remington R-25 pattern Semi-Auto Rifles and is now offered in match and service rifle lengths
