How my 16” Rifles compared:
Scar- great overall, addicting recoil impulse, expensive
Spear LT-if side charging might be Scar equal
Bren 2-does nothing poorly, great all around
XCR-ultra reliable, wish stock more intuitive, lefties might not like charging handle
Makasi-great all around, when used unbeatable bang for buck
MCX Gen 1-solid do everything gun at used prices, excellent balance
ARX100-super light, stiff controls when new, great value, most ambi, not 100% with underpowered .223 ammo
Galil Ace-ultra reliable, decent value, pointlessly heavy, would be amazing if 1.5 lbs lighter
Perun X16-excellent balance and overall weight, good ergos, rare, exotic aesthetics, great stock, okay reliability with cheap .223, expensive
Crusader Templar-blems a good value at $899, charging handle too pointy, not 100% with underpowered .223 ammo, too heavy (Gen 2’s are lighter)
556xi-some nostalgic Swiss styling elements, reliable with cheap .223 ammo, stock hard on the collar bone (personal placement), decent value if bought right ($1.0k), keymod dated, xi trim a must to swap charging handle sides
Carmel-seemed decent all around except mine was the most ammo sensitive gun in my collection - it hated / wouldn’t cycle underpowered .223, not the heaviest but could’ve stood to lose a lb
BRN180-okay reliability with cheap .223 ammo, charging handle not available on my preferred side, very light, great handling, good value when used
JAKL-pretty good all around except front heavy and the charging handle on my 13.7” was super hard to actuate at times, some stovepiping with cheap ammo, my JAKL pistol functioned better all around but was still front heavy.
LE Trade In Colt 6920-light, very reliable with cheap ammo (not sure at higher round counts), old school charging handle location, no folding stock, best non-piston cheap option though a used piston Makasi is very close for bang for buck
Cost factored in I’d probably grab a braced 11” Bren 2 pistol ahead of any of these for a go to option.
