You’re laughing but try it. Hold out a pistol at full stretch and put the barrel against the wall. See how far away you’re stood from the wall. Then do the same with an m4a1. If it’s a g3 or something really long then sure, but a short barreled rifle is actually smaller. A p90 for example is about half the length shouldered as a pistol is extended. More firepower, more accuracy.It's a long barrel AR (CYMA 069) so definitely more cumbersome than a pistol lol
