Overview
A lightweight .224 cal carbon fiber blank your gunsmith chambers to your action
The Proof Sendero Light .224 cal blank is a rifled, contoured, carbon fiber wrapped barrel a gunsmith chambers, threads and fits to your bolt action. Pick it when weight matters, the stock channel is tight, the barrel is under about 22 inches, or you want a chamber Proof does not offer as a pre-fit, wildcats included. It ships rifled and contoured with the same 1.200" shank as the stiffer Sendero; finish lengths run 18" to 24" with 1:8 twist.
Up to 64% lighter
Proof rates its carbon fiber barrels at up to 64% lighter than steel of the same contour. On this blank that is 2 lb 8 oz at 18" and 3 lb 0 oz at 24", by our own spec table.
Sendero Light taper, 1.200" shank
1.200" for the first 2.50", 1.00" at 5.50", 0.956" at 10", then a muzzle of 0.878" (18") down to 0.820" (24"). Lighter and less stiff than the Sendero while keeping the same shank.
Two variants
18" and 24" with 1:8 twist. Both leave the factory with the same shank and taper.
Steel where the gunsmith works
The shank and the last 0.800" at the muzzle stay bare stainless under the wrap, so the chamber, tenon threads, crown and any muzzle thread are cut in steel, not composite.
About 2.5 oz lighter than Sendero
At equal length the Sendero Light is about 2.5 oz lighter than the Sendero and less stiff. Proof recommends Sendero Light when every ounce matters, the barrel is under about 22", or the stock channel will not take the Sendero.

Fitment
Will it work with your build?
Works with
- Bolt actions, once a gunsmith chambers and fits it
- Standard chambers and wildcats (Proof does not guarantee accuracy, velocity or stability on a wildcat)
- Stocks with a Proof Sendero Light barrel inlet, and channels opened to 0.956" at 10" from the breech
Will not work with
- Any rifle as shipped: it is not chambered, threaded or crowned
- AR-pattern rifles (this is a bolt-action blank)
This is a blank, not a barrel you can install. It ships rifled and contoured with extra material at both ends (0.100" at the breech, a 0.625" stub at the muzzle) for a gunsmith to remove while chambering, threading, crowning and fitting it to your action. It will not drop into any rifle. Rifle barrels and barreled actions ship for a flat $14.95 per order regardless of quantity and do not qualify for free shipping.
Detail
Fitting it and the fine print
Sendero Light or Sendero?
Same shank, different taper and weight. At equal length the Sendero Light is about 2.5 oz lighter and less stiff than the Sendero. Proof suggests Sendero Light when every ounce matters, the barrel is under about 22", or the stock channel will not take the Sendero. Go Sendero for precision work and for running a suppressor, where the extra stiffness favors accuracy. The Sendero .224 cal blank is listed separately.
Will it fit my stock's barrel channel?
Proof's Sendero Light runs smaller than the Sendero but still larger than most factory barrels. Measure your channel against the contour dimensions: 1.200" for the first 3.18" from the breech face, 1.00" at 5.50", and 0.956" at 10", which Proof gives as a typical distance from the breech face to the end of the forend. Many aftermarket stocks are inletted for the Proof Sendero Light; a factory sporter channel usually needs opening up, which your gunsmith can do while fitting the barrel.
What does the gunsmith do, and what does Proof cover?
The blank arrives drilled, rifled, contoured and wrapped. The gunsmith chambers it, cuts the tenon thread, crowns it, removes the extra material at each end and fits it to your action; Proof says the job needs special tools and a qualified gunsmith. Break-in is shoot three, clean, shoot five, clean, with no moly-coated bullets for the first 100 rounds. Proof's limited warranty covers defects in material and workmanship for the original owner, with the warranty card on file within 30 days of delivery; because the barrel is one part of a rifle it did not assemble, Proof does not guarantee accuracy on a blank.
