A high-quality barrel can make or break your new AR-15 build. It can be the difference between shooting 1 MOA or 5 MOA and is the one component that can’t be easily improved upon without buying a whole new barrel. So, when it comes to making the right choice, pick a barrel with a reputation for being durable, accurate, and built from the proper materials with a comprehensive inspection process. Or choose this Spikes Tactical 5.56 chrome lined barrel that incorporates all those options with the added benefit of being affordable. This barrel is made from 4150 chrome moly steel with a chrome lined bore and chamber which is ideal for extremely large round counts and barrel life. It has also been coated with a manganese phosphate finish to provide excellent corrosion and wear resistance. Spikes Tactical barrels are built to last and will make your next M4 rifle build ready for any field conditions.

Features:
  • Magnetic particle inspected and stress relieved
  • 5 56 Chrome lined bore and chamber for high round counts and longevity
  • Manganese Phosphate coating for corrosion and wear resistance
  • Chambered for 5.56x45mm ammunition
  • Government profile for light weight durability
  • M4 feed ramps in barrel extension for reliable feeding
  • Mid-length gas system balanced for reliability and recoil reduction
  • Threaded 1/2x28 for muzzle devices like flash hiders, muzzle brakes, suppressors, and compensators
  • 1:7 twist rate for bullet stabilization of heavier bullets

This 5.56 NATO barrel also features a government profile that is designed to reduce weight while still retaining rigidity and has a mid-length gas system that combines reliability with recoil reduction. It has a .750 gas seat diameter for the attachment of a variety of gas blocks from standard to adjustable. The 1:7 twist rate is designed to be used with heavier bullets like 62 grain and higher. However, it can still shoot lighter bullets, it just won’t be as consistently accurate. There is a large amount of 62 gr XM855 military surplus ammunition on the market for extremely low prices so you will be able to shoot with this barrel all day. And because the barrel extension has M4 cut feed ramps you don’t have to worry about reliability issues no matter what ammo you use whether steel cased or brass.

The mission at Spike’s Tactical is simple, they strive to build the highest quality products offered at the best possible prices. Whether a gun enthusiast, a competitive 3-gun shooter, military, or law enforcement professional, their rifles won't let you down when it counts, guaranteed.

Spikes Tactical Barrel ST- 16" M4 LE Mid-Length

Great product for the lowest price around. Very fast shipping.

Excellent response time, shipped/arrived quickly

by

I ordered this after 11 PM at night, and received a shipping confirmation literally by 10 AM the next morning. The package then arrived at my door within 2-3 business days. It was packaged securely and the barrel is top notch. Top it off the price at primaryarms.com was much cheaper than any other site I found. Great company! Will be looking to do business with again!

Good, solid barrel!

by

light weight, solid and very accurate. It took me less than one box of rounds to get zero with iron sights. This barrel is the real deal!

Great all around

by

Nothing but good things to say about this barrel. Well done PA & Spikes. Put this on my first custom build & the accuracy was amazing. Best bang for your buck & the exception to the rule "You get what you pay for" With this you get what you pay for & then some. I can see why it's out of stock at the moment. TY from the Green Mtn. State.

Perfect service, great price, fast and cheap shipp

Spike's Tactical and Primary Arms it's like peanut butter and jelly. Unbelievable build quality, performance and ordering/shipping speed.

Great Barrel!

by

Tested multiple types of ammo through this barrel on my last build. Consistent with everything from 50 gr to 77 gr. Shot 0.4 moa with ASYM 70 gr Barnes. Shot 0.9 moa with Black Hills 77 gr OTM 5.56 mm. PMC 55 gr FMJ shot 1.5 moa. Hornady 5.56 TAP T2 shot 1 moa. Federal 50 gr varmint shot 1.6 moaReally consistent point of impact throughout. Definitely could have tightened some groups up had it not been windy. Used RR 2 stage trigger and Millet 4-16 scope with bipod from prone.

Excellent Service

This is a great barrel at a great price. Would recommend to anyone. This is my 2nd spikes barrel! Quality product.

Primary Arms does it again

by

Trying to find quality parts at a good price has always been challenging. When I do price comparisons of items online, Primary Arms is always a top contender. I've bought from them before and I'm more than likely to come back.

Very Nice!! Got here very quickly with no problems at all and was in great condition!!

Product Quality

by

What is important here is the products I have ordered are from reputable manufactures. Point is ordering from manufactures can be costly & time consuming due to the fact they make the parts u distribute them. That is where I judge U the most U have a reputation that u say got u have it. & u waste no time getting the products out to your costumers.

awesome experience.

Spikes Tactical SB5 1605-ML chrome lined barrel

Recently purchased this barrel from Primary Arms. Fast shipping. Great people to deal with. Barrel was installed on an Anderson upper / lower build. Spikes bolt carrier assembly used. Diamondhead key-mod hand guard and Diamondhead sights. Great shooting rifle and very accurate. Just added a Vortex Spitfire 1x scope. Great prices on this sight right now. Very happy.

Spike's Tactical 1605 AR15 barrel

by -

Recently took delivery of this Spike's Tactical 1605 barrel. I assembled my new build and checked headspace. Perfect ! I've shot 50 rounds of 77 grain Sierra hpbt over 23 grains of Varget and accuracy is superb. Open sights I consistently get 2" at 100 yards. I expect accuracy to get even better as I put more rounds down range. As always Primary Arms ships fast and supplies great components.

Better then expected

by

A new build i started decided on this barrel. It was a good decision. 3 shots at 100 yards sited in my Vortex 1-8 . Next shot was 400 yards steel. Hit it 15 times in a row 3" group I was seriously impressed.
