Glock shooter Posted October 3, 2009 Share Posted October 3, 2009 I am kicking around the idea of installing a suppressor on my new .308. I would like to get some feed back from other on how threading the barrel effected the accuracy and suppressor install. I know I risk the chance of changing barrel harmonics by threading it. Is it worth it or just leave well enough alone? Current rifle set up: Rem. LTR 20", X-pro trigger, Burris 3-12 XTR. Best two 100 yard groups .365" & .461" with Fed. Gold Metal Match 168gr. Thanks for any info, Jason Link to comment Share on other sites More sharing options...
Ken Kwiat Posted October 12, 2009 Share Posted October 12, 2009 Hey Jason, Your accuracy shouldn't be affected negatively by adding the can alone. If you're interested, there's many postings on this topic over on SnipersHide. Your POI will likely shift but if you shoot with the can all the time, it's not an issue (re-zero and go to town). And, you as a shooter will benefit from the recoil reduction & muzzle blast reduction. They basically act as very effective muzzle brakes. They are popping up more and more at the LR Tactical matches. Enjoy. Link to comment Share on other sites More sharing options...
trip5466 Posted October 16, 2009 Share Posted October 16, 2009 Getting a can with a solid compensator is the way to go. You don't have to worry about screwing up the threads if you plan on taking it on and off alot. I recommend Surefire- my shift is negligable and the break is great without the can...the only way to go on big bore! Additionally, the Surefire shift(very small) remains constant when you take the can off and put it back on. That is data you need if you are buying a can. Some cans impact shift changes everytime you take it off and on...guys on military long guns and the associated cans see that alot. Link to comment Share on other sites More sharing options...
trip5466 Posted October 16, 2009 Share Posted October 16, 2009 Also, 20" barrels usually perform better with cans since the shorter barrel's harmonics are not as effected as much as longer barrels so you should have good grouping with your LTR.

Thanks guys for the feedback. I have known about the Surefire break/can combo. Had not given it a thought that the with the impact shift, its maintained by the break. My origninal plan was to go with direct thread to the barrel. But, now I will have to re-think the Surefire route. Link to comment Share on other sites More sharing options...

I've got a couple and use them on a number of different rifles. There is definitely a POI shift between can/no can. Not a biggie at 100yds, but more significant at longer distances. All my rifles will shoot better groups with the can but the groups are in slightly different locations. If I only had one SF can on one rifle, I'd think it might simply be that particular suppressor, but when it happens with multiple cans/rifles, I'm concluding there's an inherent POI shift. The advice about getting a brake or compensator style attachment is good. The Surefire set up is nice but pricey. I believe Yankee Hill (and possibly others) make a similar set up. I have no experience with others. The Surefire system is very good. David Edited October 29, 2009 by dt1 Link to comment Share on other sites More sharing options...
JoshF Posted October 29, 2009 Share Posted October 29, 2009 (edited) I believe AAC just came out with a brake style adapter as well. Their cans have always been ranked pretty high in comparisons.. Might be worth checking out. http://www.advanced-armament.com/product.a...pid=149#pid=177 Edited October 29, 2009 by JoshF Link to comment Share on other sites More sharing options...
fastshooter03 Posted October 29, 2009 Share Posted October 29, 2009 Here are some groups I fired last weekend getting ready for deer huntin: Rifle is a DPMS AP4 16"With a YHM Suppresor(screw on)--Scope 2.5-10 Weaver Extreme(junky but it works) Top 3 were fired then I adjusted the scope down and fired the rest. Range was 100yds. Ammo mag fed. Load was probably a 168 PP bullet with LC brass, WLR, and benchmark or something similar. Sorry but I didn't shoot without the Supp. Nick Link to comment Share on other sites More sharing options...

He wasn't saying that there wasn't a POI shift. He's saying that the shift is repeatable as you attach and remove the suppressor multiple times Link to comment Share on other sites More sharing options...
