i bought 2 mini silver, within 2 boxes paint 1 had gone very simalar to your bolt guide tip had worn hideously as well causing air to leak, kee had back agreed to send me new mini red
well 1 or 2 boxes paint heavy gauge (a ring around bottom bolt,at the position were bolt in photo starts going up), remove bolt clean try again each time bolt remove retried gauge would go further round the bolt until full 360 degress, then gauge went up to the tip just as in photo but also gauged the boltguide this time at the rear upto the first oring,all this under 4 boxes paint. this has also been returned to kee ,i been told full refund, still awaiting it
ps 1 of first silvers i bought has done 20ish boxes paint , the bolt has 1 small nick on it 1mm long, bolt guide was perfect untouched until now when a very slight mark has appeared on bottom tip of the guide, was only used for a couple games as i know have ego7, mini was used by m8 as his dm6 went down
personally i think invert should start selling mini with derlin bolt as i now read this is safest way to assure no damage, or they need to redisign the bolt / bolt guide
edit i just read bolter saying possibly not enough lube,garaunteed there was enough lube, most damage appeared as from fact lube
