Hi all, new to this forum & was after some some info on the 48 spring guide. Just purchased a tuning/service kit from Tw chambers here in the uk but the spring guide is in 2 pieces, & where as i,m sure your all aware the original guide is 1 piece & rests against the first of the inner two sleeves of the trigger unit this chambers Guide rests against the innermost sleeve (retains ball bearings) seems wrong to me & may have a detrimental effect any info would be most appreciated.
