Reply To: air arms s510. limited edition
I have the Ultimate Sporter version in .177 with Q tech moderator. It ihas the same action as the s510,which is buttery smooth. This is a proven design especially in the smaller calibers(.177,.22). The fit and finish rivals more expensive PCPs.
At half power in .177 it shoots an Air Arms Heavy 16g pellet(this ones pellet of choice)on average 900 fps and getting 50 shots. At 50 yards do like to crank it up to full power and 1/2 inch groups are normal but shot count goes down to 30 while producing 24 fpe in .177. On low power shooting at 10 meters I stopped counting at 100 shots and makes a great 10 meter rifle. I have had zero issues with this airgun and it has performed flawlessly.
