czgunner 0 Posted June 14, 2007 Report Share Posted June 14, 2007 I want to buy an FBMG 20 round mag body and use my 8 round follower and floorplate to make another 20 rounder. What spring does the 20 rounder use? Quote Link to post Share on other sites

czgunner 0 Posted June 15, 2007 Author Report Share Posted June 15, 2007 I'll take your word for it, but that sounds counterintuitive! Quote Link to post Share on other sites
snake54 0 Posted June 17, 2007 Report Share Posted June 17, 2007 The 8 round spring is plenty long for 20 rd mags. Quote Link to post Share on other sites
netpackrat 566 Posted June 17, 2007 Report Share Posted June 17, 2007 My .308 came with a 5 round magazine. Will the spring from that work with an FBMG mag body? Quote Link to post Share on other sites
SOPMOD 254 Posted June 20, 2007 Report Share Posted June 20, 2007 I'll take your word for it, but that sounds counterintuitive! Take that massive spring out of your short magazine and look at it,it is stiffer and has more coils than a USGI M14 magazine spring. Quote Link to post Share on other sites
cscharlie 107 Posted June 20, 2007 Report Share Posted June 20, 2007 The factory 8 round mags use a russian 20 round spring. Quote Link to post Share on other sites
