  • Service opens gas ports in barrel and trunion

If your MPX does not cycle low velocity rounds, we can help out!  This service includes removing the gas block, drilling out the gas port (barrel and block), and reassembly.  We only need your barrel sent in.  We open the barrel to .0625" port size.  Turnaround is 2-3 days.
Ship all barrels to our address:

    have only got to shoot once since I got it back but it seems to be performing a lot better shot 400rds through it without one problem seems to have fixed the problem my mpx was having.

    I haven’t had a chance to shoot my MPX post gas port opening (just got it today), but all looks well. Shipping, service, and communication was on time!!! Very happy I didn’t use the other company that does these! Ya know, the one that says they are ignoring you on their answering machine. You guys (ZRTS) will get rich doing business this way!!
