The TX is our threaded receiver / barrel version with a removable rear hold down lug. The point of a threaded barrel is to have the most rigid mating between the barrel and receiver without the 'barrel droop' of using a single point v-block. The barrel is threaded into the receiver and then securely fastened in place with our proprietary barrel nut. Once these are located properly and torqued into place you have the most rigid 10-22 type platform available, period. It allows you to use an 18" or 20" bull barrel and have it free floated without worrying about droop or heat induced movement. Couple that with our 7075-T6 receiver material and removable & reversable Picatinny rails in 0, 10, 20 & 30 MOA variations and this gun will shoot out to the absolute limits of the .22lr round with accuracy. For the running & gunning crowd we will be offering the TX barrels in our popular new stepped and fluted design to get the best of both worlds. The gun will sport an 18" barrel but because of the stepping / fluting it will weigh LESS than a 16.5" straight .920" bull profile barrel.
In the past it was a pain to find a stock to fit these into as they all needed custom inletting and none used the rear lug hold down. But we now have that part in process to offer you a precision, drop-in stock that will accept both the standard 10-22 with v-block or the TX version of our DAR-22 / TUF-22.
We got it goin' on man.
