tnorman Posted March 22, 2015 Share Posted March 22, 2015 I have a nordic tactical comp on my rifle. I have noticed when I try to make multiple shots in succession it dips hard. The comp doesn't have a hole in the bottom so I was wondering is it safe to add a port hole to the bottom of the comp. Link to comment Share on other sites More sharing options...
dauntedfuture Posted March 22, 2015 Share Posted March 22, 2015 To date i know of no comps that have holes in the bottom. I would consider that something else it going on. You might think about and or consider other factors that are throwing your rifle forward. Do you have a Full Mass Operating System (FMOS) if you do then you might think about Light Weight (LW) components. Also consider an adjustable gas block. Its more likely that your bolt slamming forward is driving the run down then anything else. As far as safe goes, yes its safe but i would not do it. I don't think that a hole in the bottom will do much.. Link to comment Share on other sites More sharing options...
Steve RA Posted March 22, 2015 Share Posted March 22, 2015 If you never shoot prone, no problem. Main reason comps have no holes in bottom is the dust cloud developed with gas directed down. Also you would not want to use the top of your car as a rest with a hole in the bottom. Link to comment Share on other sites More sharing options...
tnorman Posted March 22, 2015 Author Share Posted March 22, 2015 (edited) I have a lmos in the rifle. I finished removing weights from the buffer today and tuning the gas block. It shoots really soft. It just dips down noticeably when I fire more then 2 shots in rapid succession. Edited March 22, 2015 by tnorman Link to comment Share on other sites More sharing options...
Steve RA Posted March 22, 2015 Share Posted March 22, 2015 Take the comp off and see what it does ??? Or try a different comp - if you have or can borrow one. Link to comment Share on other sites More sharing options...
tnorman Posted March 22, 2015 Author Share Posted March 22, 2015 I may do that next time I go shoot. I have a JM comp on my other rifle. I bought the Nordic for this one just to try something different. Link to comment Share on other sites More sharing options...
michael1778 Posted March 22, 2015 Share Posted March 22, 2015 Some compensators apply too much down force on the muzzle. I'm getting less and less tolerant of that as I get older/wiser. I don't need more reasons for the muzzle to jump around! Link to comment Share on other sites More sharing options...
tnorman Posted March 22, 2015 Author Share Posted March 22, 2015 I think the three holes in the top of the comp is what is pushing it down so hard. Link to comment Share on other sites More sharing options...
LoganbillJ Posted March 23, 2015 Share Posted March 23, 2015 Tap the holes and add a set screw to remove downforce. The taccom comp is done this way. Link to comment Share on other sites More sharing options...
Corey Posted March 23, 2015 Share Posted March 23, 2015 Does it dip hard when someone else shoots the rifle? May be something attributed to shooting style rather than the gun itself. Link to comment Share on other sites More sharing options...
Don_B Posted March 23, 2015 Share Posted March 23, 2015 You can also enlarge the exit hole to allow more gas to escape through the muzzle which will make the comp less effective. This should help on the dipping if you decide the comp is the issue. Link to comment Share on other sites More sharing options...
Therealkoop Posted March 23, 2015 Share Posted March 23, 2015 I find that the nordic corvette overcomps for me as well. Drill/tap the center hole with a set screw as stated above. Link to comment Share on other sites More sharing options...
