Re: Quicky Question: Controlled Round Feed
Speaking for the FN SPR, PBR-XP and TSR-XPs:
In 2003, FNH conducted a 15,000 round endurance test of one SPR-A1 in .308 Winchester. During the test, we fired the entire test in 5 round sequences from six 4 round DBM magazines. That meant we had to thumb-load into the chamber the first round of each sequence. The extractor therefore snapped over 3000 cartridge rims. During the test, the extractor never failed to feed, extract, or perform in any other way. In fact, no part of the rifle failed to perform as designed except for three of the DBM magazines. We lost three of them to spring fatigue. Based on that test, we redesigned the spring.
Many things we buy today (appliances, cell phones, cars, etc.) are built to last only a few years so we are inclined to buy another one when it wears out. Firearms are an exception to that rule (most of them, anyway). When properly maintained and operated, they will last a lifetime, maybe two or three. How many Springfields and Mausers built in the early part of the 20th century are still serviceable?
I am lucky and very proud to work for FNH USA. We build a lot of pretty damned good firearms. I am most impressed and proud of our SPR/TSR line, always have been. Mostly from first hand experience. Even if I did not work for FNH USA, I'd still shoot SPRs.
Semper fidelis,
