Spikes Tactical SB5 1605-ML chrome lined barrel
Bill from MO wrote on September 15, 2016:

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.

Great barrel.

Barrel came soaked in oil. Awesome! (no sarcasm). Installed straightforward and took all parts as expected.

Great Barrel!

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 moa Really 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.

It's a no brainer.

Great all around

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.

Excellent response time, shipped/arrived quickly

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 was much cheaper than any other site I found. Great company! Will be looking to do business with again!

awesome experience.

Great chrome lined bore/chamber barrel for the money. I'd give a few dollars more if it was pre dimpled for a gas block. Have yet to test fire (build in progress)

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.

Perfect service, great price, fast and cheap shipp

Ordered this as part of a build for my father-in-law for Christmas. The barrel came quickly and the order process was painless and quick as well. Great job, folks!

Everything about the barrel is perfect the finish, the fit and the look. Haven't shot it yet but so far so good.

Product Quality
brad keene from NE wrote on August 10, 2015:

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.
