Detailed Description

Nearly two decades of building the finest custom tactical AR-15 rifles have given us the insight to develop a comprehensive line of stainless steel, match grade barrels that offer superior accuracy, reliability and longevity for your next custom AR rifle project.

All Wilson Combat Match Grade AR-15 barrels are precisely crafted of the finest American-made 416R rifle rated steel on computer controlled equipment to our exacting list of technical specifications. These proven barrels feature a hand-polished bore and feedramps and then complete a rigorous final inspection process that ensures your new barrel will meet your most demanding expectations. All barrels feature crisp CNC markings, precision muzzle crown and a chamber and gas port optimized for reliability.  

300 AAC Blackout

The 300 Blackout (300 BLK) was designed by Remington/AAC to create a reliable, compact .30 caliber round for the AR platform that uses a standard bolt and magazine. 300 Blackout is optimized for suppressed fire with heavy bullet subsonic loads but can also be used with supersonic ammunition when extra range is needed. The 1-7” twist will work well for subsonic and supersonic loadings alike and there is typically no need for an adjustable gas block when switching back and forth between the two loadings.

Tuned for outstanding reliability, the Wilson Combat SBR (Short Barreled Rifle) Tactical is our smallest Custom High Performance AR rifle barrel.  Highly portable and hard hitting, the SBR Tactical upper will transform your registered lower into a superior carbine for close quarters operation. Medium taper is ideal for high rates of sustained fire.  You will love how quickly and easily the SBR Tactical balances and shoots. 

Note:When assembled into a Short Barreled Rifle, all NFA rules apply.

(Note From ATF Website)

Q: May a FFL or an individual legally possess the parts to manufacture an SBR or SBS as long as no firearms are actually assembled?

A FFL (Type-7 or Type-10) who pays the Special Occupational Tax (SOT) may possess parts required to assemble NFA firearms. A non-licensee or FFL who has not paid the SOT is required to register any NFA firearm via an ATF Form 1 (5320.1) prior to acquisition of the parts required to assemble such firearm.

NOTE: Use in conjunction with Lo-Profile gas block for best reliability.

Flawless 8/1/2019
First Pistol build and first ever using Wilson’s products. The fit and finish is amazing. I paired the barrel with their Low-Mass BCG. The two worked in perfect harmony. No cycle issues, ate it up and spit it out. I finally was able to make it to the range today and was just amazed. Glad I went with this set up.

Incredible Accuracy 5/30/2018

blown away 4/8/2018
I put the 8in 300blk in a pistol build soon to be sbr suppressed. Unsuppressed shooting hornady American gunner 125gr hpbt, I was able to shoot 1in groups at ~105 yards from a rest with a scope for testing. There was about a 3-5in drop from 50 to 100 yards but consistent 1in groups at 100 yards! my 16 wilson 556 barrel wont do that as consistently so Im over here scratching my head, very impressed and blown away.
Excellent SBR/Pistol barrel 1/15/2018
Purchased this 8 300 Blackout barrel for a suppressed AR15 pistol build. I had Wilson add the Grey Tuff Armor cerakote. The barrel looks and shoots phenomenal. High quality was easy to find in the finish, fit to the receiver, rifling, threads, logo, feed ramps, and range accuracy. I was impressed to receive the barrel in such a timely manner even with cerakote being added and shipping over the holidays. Not to mention, picked it up during the end of year sale for about $50 off. Will happily buy another Wilson barrel for my next project 6mm AR.
