Hey all,
I used to shoot a Bushmaster XM15 flattop M4gery, 14.5" barrel with permanently pinned FH, Samson MRFS-C freefloat handguard. Now I've got a Bushmaster flattop Dissy with a cut down 16.5" gov't profile bbl (rifle length gas system with enlarged gas port), KAC M5 RAS, and all the same accessories I had on the M4gery (big 125 lumen Surefire light, TD foregrip, KAC rail panels, CQ/T as primary optic).
My questions are these:
(1) Since my handguard is no longer freefloating, how much will using a 3 point sling affect POI if I pull the sling tight to support offhand shooting? I'm not talking super-tight, just enough to support some of the weight on my weak-side arm.
(2) How much will a rail mounted bipod affect POI?
(3) If shooting with a single point sling, how long should the "average" shooter be able to hold the gun steady enough in the standing offhand position to repeatedly hit an 8" steel target at 50m?
(4) When transitioning to prone position, can you use a collapsible buttstock (I have an ACE SOCOM) to break your downward movement, or is it still a big no-no to strike any part of a gun on the ground?
I'm sure these questions have been answered in various posts, but I'd rather not spend the next hour searching for them...
Thanks!
