This bolt is great it does everything they say it will do, gives better distance when used correctly and good accuracy. I got the bolt in white derlin and love it. The best part is you never have to lubricate it. Just put it in and leave it there, no maintinance!! It increased my accuracy at long range and lightened my internals setup on impulse which allowed higher ROF and better consistancy.
Bolt is great i highly recommend it. If you got the money and want better range and accuracy out of your impulse the get this bolt.
