I think I'll finally start to refinish my small stash or pre-bans. I plan on upgrading my followers to the Magpul anti tilts. Is it worth upgrading/replacing to a new spring?
Thanks in advance guys and gals!
First of all, upgrading followers on pre-bans to the latest anti-tilts is an excellent upgrade. Magpuls are the most high;y recommended, and prices have come down quite bit from long ago. You can resell the old black or green followers - there are a few folks who still want those.
As for springs, IF THE MAG FUNCTIONS FINE, keep the existing springs. If they are comparatively "weak" (based on your own subjective tests or observations), then a replacement is also worthwhile. Its up to you if you want stainless or chrome-silicon springs. I see no diffeence functionally and as far as durability/longevity, it didn't matter too much unless you're in a humid region (I live in a humid region, but I have lots fo spare springs).
IF you replace the springs, KEEP THE OLD ONES ON HAND. As someone already noted above, some replacement springs are wider/narrower. I have found some to be just 1/2" shorter, and that half-inch soetimes made a world of difference in that the new slightly shorter spring would curl inside the mag and prevent it from taking in rounds 29 and 30. Putting the old original springs back in resulted in easily getting all 30rds loaded. So I sent the "new" springs back.
So, new springs need function checks. New anti-tilt followers, especially from MagPul, will almost always work from the get-go.
