Problem encountered. - Leapers UTG AR15 A2 Fixed Stock Assembly

I purchased this stock because I wanted an A2 rifle stock to complete my rifle's look. After assembly, which was flawless, when the rifle was tested it had problems with FTF traced to failure to load, regardless of magazine used. Because everything checked out, I decided to compare the recoil spring from the A2 stock with another rifle's spring, and found my spring to be 2" shorter than the sample. Replacing the Leapers spring with the sample cleared up my malfunctions, so I suspect the company shipped this rifle stock with a carbine length spring. I had to find and purchase the correct length spring to get this rifle up and running. The stock itself is strong and dead black in color, which is fine, but the supplied spring caused me malfunctions.
