REVIEW BY: Sempre Valente Sunday, January 26, 2014
I was looking for a basic 4x20 scope priced to match my Colt M4 22LR. I wasn't about to stick a $500 scope on a $500 rifle. Since I opted for the model with the carry handle/iron sight, I wanted to mount the scope on the handle. I was more-than-pleased to stumble on the BSA TW4x20. It mounted easily atop the handle, and fit perfectly. I get a lot of compliments at the range because "it looks so cool." The lenses allow plenty of light through. Sighting is no-nonsense quick. With the match-grade barrel and decent ammo, I can rip quarter-size holes at 100yds. At $50, I'd have to say I got more than my money's worth just in quality of construction. It's so much more fun with the scope mounted, I left it on permanently. Oh, I can still peep through the U-channel under the scope when I want to.
