So i have read for awhile on here about people tuning their guns/ upgrading them to make them extremely accurate. Yet i gave a couple of my guns to the awesome people at Airsoft Outlet NW to upgrade. I got em back and they run awsome and very smooth yet i still have a wide spread when shooting at a 100 feet away target.
I personally think i may not understand how to adjust my hop up correctly. Advice?
Or if you think it could be something else, feel free to comment.
BTW the guns im talking about are a Classic Army M4 carbine and a G&G Sig 550.
