Length of pull
Before we begin, I want to say a word about the length of pull you get with this adapter. I gave the range of lengths in Part 1 as 14-1/8 inches to 17-1/8 inches, and that turned off many readers. In terms of conventional stocks, that pull range is very long! But Dave Rensing, who invented this adapter, made it for his 8-year-old son and his 7-year-old daughter. The son uses it conventionally, but the daughter collapses the stock past the first detent so it’s even shorter. Fully collapsed, the pull length measures exactly 14 inches but feels like 11 inches.
