Wilson Combat Ranger Profile Barrels

Our Ranger profile barrel is the lightest profile AR barrel that still retains match-grade accuracy as the rifle heats up from rapid-fire shooting.

300 HAM'R

  • The 300 HAM'R was developed for optimal terminal performance in a standard AR rifle - and offers near .308 Winchester effectiveness while exceeding the ballistics of the famous 30-30 rifle - the most popular hunting cartridge of all time.
  • The 300 HAM'R cartridge has 18% more retained velocity, 40% more energy and a 56% flatter trajectory than the 300 BLACKOUT at 200 yards!  The 300 HAM'R has amazing accuracy and low recoil in a lightweight, compact standard AR platform rifle that uses a standard 5.56 Bolt.  We recommend a 300 Blackout magazine for best overall reliablilty.  Ammuntion and reloading dies/info is available from Wilson Combat.

Wilson Combat AR Barrel Service Policy

Because of the nature of the AR parts business and varying pressures of commerically avaiable ammunition, Wilson Combat cannot guarantee function in customer built AR rifles.  We recommend all components be installed by a competent rifle-smith.

If you assemble a firearm with Wilson Combat components and it fails to function, you first need to check the fit of the barrel to the gas block and the overall condition of your rifle's gas system/bolt carrier group to ensure your system isn't leaking gas.  As buffers and springs play a role in overall reliability, the use of an aftermarket style buffer system is not recommended.  When using an adjustable gas block, reliability is best achieved at the fully open setting without any gas port restriction. 

Wilson Combat will not troubleshoot customer built firearms/uppers.

If you feel a Wilson Combat component is defective, please return the component only to us using our Return Form.  Shipping to Wilson Combat is the responsibility of the consumer.

300 HAMR Build Badassery
I recently built an upper using this 16.2 ranger 1-15 300 HAMR barrel. Fortis forged upper, and fortis 14.4 night rail, Superlative arms gas block, Rubber city BCG, TBAC CB break. It is absolutely badass as advertised, and it shoots-- really well... I have tried several different loads: 110 barnes, 110 VMAX, 125 FMJ, 125 TNT, 125 PH w/ cannelure and 135 HP. The PH and the Barnes shot the worst, ~1.5 MOA. Everything else was MOA or better, which is pretty sweet for OTS ammo... Was able to reach out to 500 yds with it no problem, don't think it would be great application to hunt with, but fun for ringing steel. The recoil is very mild, especially with a tuneable gas system. Shot some squirrels with it, the TNT and VMAX didn't give me the crazy expansion I was hoping for. Haven't shot any pigs or white tail yet, but I am confident it will do the trick. It doesn't work great with 5.56 PMags, I really like the lancer 300 Blackout mags for it. I am sure I forgot something, but, this is a badass cartridge, just don't buy all of my ammo... Stay free
Tack hamr
This thing is absolutely amazing. 30-30 proformance with pin point accuracy. 300 blackout who?
