What would've happened to his groups had he released all sling tension for some of those rounds? How about if he rested the mag on the ground, or shoot off a hood of a vehicle, or around a barricade?

Ammo has nothing to do with it. MK262 was used for the tests.

The guns were zeroed by each shooter off of a bench. Then 2x10 round groups were fired at 100 and 200 off the bench as the control. Then 10 round were fired from 10 different alternate positions. Ie- 1 shot mag mono podded, 1 shot off a hood, 1 off a barricade, 1 with a vertical fore grip, 1 with a flashlight added, 1 with a Peq15 mounted, 1 with a tight sling, etc. Then the forends were swapped, guns were rezeroed and the whole thing was repeated.

The differance in group size between floated and non float off the bench ranged between .5 MOA and 2 MOA. The newer shooters had the most deviation presumably due to inconsistencies in hold. The best shooters showed little difference. Again off the bench. Once the alternate positions were shot the differences were huge.


That specific test was about more than just handguards, but for a field gun, a FF handguard is probably the best investment one can make.


Actually nothing with my buddy. His sling without a float tube was tied off to the barrel nut in front of the mag well basically.... easy enough to rig that way with a web sling. And the other varying positions, no difference because he is a shooter and knows how to deal with things, other than neither of us would ever rest on a mag... would rather use the sling if we had to do a mag rest...
Though a BIL used the mag rest a few times trying to cheat at a couple of matches and I asked.... said his impact never varied. Hard to believe for me, but I never did see him touch his rear sight.

I'd think that most of the variation would be shooter error, BUT shooter error won't go away from floated to not, so the error would be there but evidently the consistency gets better.

Its like my arguing that bedded rifles shoot better than non in the AR. They do. I shot enough groups to prove it. Not much better. But some. And much more round groups then once bedded...

Not enough to worry until you get good though.

But as noted, bottom line, float tubes are cheap, I'm betting you can find an ebay one for 50-75 bucks.... why not....

I'd take a good barrel ANY day over a float tube though. Trigger doesn't really matter, you can shoot just about as good with a crappy one as a great one, that is mostly in the head... but they make it eaiser to shoot well... a good trigger that is.
