  1. Solid value on a good shooting barrel

    Posted by Mike on May 10th 2016

    Very small debris visible with bore sight would not come out with bore brush, came out with a test round , and nothing visible afterward. Shoots very accurate , impressive accuracy for the price range, this is probably my 4th Spinta barrel now and they are consistent.

  2. great quality as expected.

    This is my 3rd barrel from S.P. The quality of the barrel is first rate. They ship so fast your head will spin. Go ahead and buy it.

  3. Top quality barrel.

    I have ordered several barrels from Spinta and have been very pleased with each one. Their packaging is superb and far better than other companies packing. The barrel is great and very accurate. Their barrels are equal to and in most cases better in accuracy than other companies barrels that charge twice as much. Keep up the good work.

  4. Excellent value

    First off,the packaging was amazing. USPS could have dropped it out the window as they flew over and this barrel would have been ok. The finish is even and not a mark on it any where. Fast shipping, well packed and exactly and more than I was expecting. Will be buying more.

  6. impressive accuracy

    This is the second barrel I have purchased from Spinta. I was impressed with the finish when I received the first barrel. A quick trip to the range revealed impressive results. This barrel , with quality ammunition, is capable of producing extremely tight groups. For the average , weekend shooter , this barrel is an incredible performer. High end performance at a budget price.

  7. getting more than you pay for

    Recently purchased my first barrel from Spinta. Item was received quickly and was securely packaged. I was pleasantly suprised when I removed the barrel from the package. This barrel was purchased based solely on price for a budget build I was doing. Fit and finish are outstanding.The barrel performed well during my first range/break-in session. I would not hesitate to use Spinta products on my future builds.

  8. 100% Satisfied Customer!!!

    Yes...there are better barrels being being made (With hefty prices as well!!) but most of us will be well served by Spinta Precision barrels I am sure. And looking over other manufacturers barrels....I have to question now why would we with the availability of these Spinta Precision barrels?!
    I have purchased now a total of 6 ( 7 maybe? ) barrels from Spinta...three in 7.62 x 39. With known issues that people have getting a 7.62 x 39 to feed and function through a AR 15 can be irritating which most all problems barrel related. I am happy to report that these barrels feed well...cycles well. I cannot speak for accuracy at this point since I build AR's as a hobby so when I get builds completed...these are stored. I do run approximately 100 rounds in break in...clean between shots and test firing again and I have not had a single cycling issue...not one.
    I was assured by Spinta that Spinta Barrels would eat up 7.62 x 39 ammo....they do and I will buy more Spinta barrels in this caliber and I am well satisfied with rapid shipping...visual consistency of finish and function.
    I have already installed/tested/broke in this 5.56 barrel for this review...same performance and finish as the other Spinta barrels. Did not have a headspace issue. What I do need to do is set up this AR with optics to test for accuracy and will do that soon. Most of my shooting is close range practicing where function/reliability is a must...Spinta is passing my style of use and that is pleasing!!
    Thanks Spinta for providing nice barrels at prices that makes it possible for me to build more AR's. You've got me as a excellent reference!!
    Now if only possibly someday Spinta Precision will have enough requests for a 6mm x 223 barrel/s...I would order one!! Or three...more.
