7075-T6 Aluminum Barrel Nuts and Titanium Screws are in stock and shipping!!


If you're looking to shed some weight from your AR rifle or pistol with a Noveske-spec rail, this is a great way to do it!  

Barrel Nuts are machined from US-made 7075-T6 Aircraft Grade Aluminum then tumbled and coated with CeraKote Graphite Black by the good folks at Icarus Precision in Washougal, WA.  We've tested these Aluminum barrel nuts on everything from precision builds to select-fire M-16 guns with zero issues and completed torque testing by taking the nuts to 90 ft-lbs, though we do not recommend, nor will we warranty over-torquing!

Designed and machined by Americans at a Veteran owned machine shop in Washington State.


Factory steel Noveske barrel nut weight(does not include screws):  3.0 oz/87.8 grams


BLP 7075-T6 barrel nut weights(does not include screws):  Approximately .84oz/23.9g


We have changed the factory Noveske mounting screw thread pitch from 10-24 to 10-32 thread pitch in an effort in increase clamping force and reduce the possibility of cross-threading.  All barrel nuts ship with six STEEL 10-32 hex head cap screws with Titanium versions also available as an option.

You will not be able to use your factory Noveske install wrench and will instead need either a 30mm or 1-3/16" crows foot.  We realize this is a bit of an inconvenience, but it was done for strength reasons.

30mm can be found here: https://www.amazon.com/Sunex-97330-2-Inch-Crowfoot-Polished/dp/B002YK9QB8/ref=sr_1_1?ie=UTF8&qid=1513837620&sr=8-1&keywords=30mm+crows+foot

1-3/16" can be found here: https://www.amazon.com/Sunex-97738-Crowfoot-16-Inch-Polished/dp/B0074HN8BA/ref=sr_1_2?ie=UTF8&qid=1513837620&sr=8-2&keywords=30mm+crows+foot


We recommend a torque value over 30 ft-lbs and under 50 ft-lbs using the three step method prescribed per milspec including use of anti-seize or install grease. 


Fits the following rails/handguards:

Any Noveske NSR, NHR and NQR 5.56/.223/.300BLK size.  MAY also fit PSA and other 5.56 sized rails that use pinch clamps along with a 1.347" to 1.52" O.D. barrel nut(34.22mm to 34.34mm).  Please confirm with calipers before ordering.
