Seal the deal. I just did the same thing a month ago. Since the Norinco front trunion has the serial number, it is not removed and the Bulgy barrel is turned down to fit the Chinese trunion.

yes. the trunnion will need bored oversize to fit the bulgarian ak-74 bbl.'s journal.
depending on how the job gets done, hopefully you have a virgin bbl. with no cross pin slot in it. some builders will weld up the trunnion holes to offset them a millimeter or so. also, you may want to use a romanian 'narrow lug' ak-74 bolt to get the bbl. seated to the standard depth (russian and bulgarian ak-74's use the wide lug bolt). many aks-74u krinks and aks-74's have been built on the 84s receiver. it just takes a bit more work and forethought. |

CAMPY, which of our noble smiths would you recommend to do this?

and ... the plot thickens! Im psyched now!
Campy.. I would approach the barrel conversion as this. Turn down the barrel to match the Trunnion on the 84s... Now saying that, explain the smaller lugged bolt thingy to me and how it relates to the lugs on the 84s trunnion.. show some pics of that conversion Raptor!! We need to see that man.. Tim |

What I meant was that I just bought a Norinco 84S. I am trying to decide who to send it to for a Krink conversion. The method I stated was the scenario mentioned by Troy Sellars of InRange C2. I am trying to find out which method works best, enlarging the trunion hole or turning down the barrel. |

Norinco 84s transformed into Bulgarian AKS-74. Every question you had earlier is answered in the picture. Built originally by The 4 Seasons Gunsmith...and made operational by Troy sellars of In-Range.

most smiths turn down the bbl. journal...it's just easier and faster. most smiths have a lathe. not many have high precision boring equipment or a jig grinder.
there are several style of bolts. all bolts have two locking lugs and a stem. the locking lugs engage the locking shoulders on the trunnion when the rifle is in battery and ready to fire. the stems come in 'large' and 'small' diameters. the ak-74 uses a small diameter bolt stem. the lugs come in 'narrow' and 'wide' styles. the ak-47 and akm used narrow lugs. russian and bulgarian ak-74's use wide lug bolts. romanian ak-74's use narrow lug bolts. when matching/headspacing a bbl. to a trunnion, a gap must be left that allows the bolt lugs to lock up against the shoulders on the trunnion with the headspace dimension in tolerance. your chinese rifle is basically a .223 akm. |

Thanks for that crucial info campy...So one of the parts that I will have to get is a Romanian AK74 bolt. (writes that down)
Fistpoint, could you install a Bulgarian side rail mount on that baby and still have the stock fold correctly? How is the mag-jiggle in that AKS-74? I have heard on here that the .223 rifle recievers make great conversion doners for a 5.45 but mag-jiggle is a concern with me. Tim |
