pcs352 Posted October 2, 2015 Share Posted October 2, 2015 Like the title says do adjustable gas blocks foul easier due to reducing the port size? Reason I inquire is my shooting buddy's rifle went down during a match and after a thorough cleaning some crud came out of gas tube. After the cleaning the rifle runs great. He was using an adjustable gas block and I use the same one (SLR) and want to know if there is a maintenance/cleaning interval I should be performing. Let me know if you guys/gals do anything different with your adjustable gas builds. Link to comment Share on other sites More sharing options...
Paul-the new guy Posted October 2, 2015 Share Posted October 2, 2015 SLR told me that I should screw it all the way in and then back it out after every shooting session/match. Link to comment Share on other sites More sharing options...
mpom Posted October 2, 2015 Share Posted October 2, 2015 2 different issues. Believe recommendation to close and open is to prevent threads getting caked up w crud and causing adjustment screw being frozen in current setting. Would think the port itself should not get plugged with crud, as high pressure gas would keep it patent, but could be wrong. If i am wrong, perhaps opening up adjuster screw and firing a couple of rounds would be a good move. Link to comment Share on other sites More sharing options...
pcs352 Posted October 3, 2015 Author Share Posted October 3, 2015 The screw it in and back it out actually makes a little sense....I'll give that a go! Link to comment Share on other sites More sharing options...
MarkCO Posted October 3, 2015 Share Posted October 3, 2015 Like the title says do adjustable gas blocks foul easier due to reducing the port size? Yes. Unless I absolutely need one, I avoid them for that reason. Increased erosion and increased Carbon deposits. The metal and deposits get carried into the carrier and thus the gas rings. In some cases that can cause stoppages. Link to comment Share on other sites More sharing options...
