Annihilator Posted September 22, 2020 Author Report Share Posted September 22, 2020 I think the bolts are interchangeable but the MP18 bolt will only operate in the full auto modeBut i think the extractors are not exactly same. I will post a pictureDo you still have MP 28 bolts?Pierre Link to comment Share on other sites More sharing options...
johnsonlmg41 Posted September 23, 2020 Report Share Posted September 23, 2020 Lanchester. Sarco has them. I will say most will require fitting. Even all MP18 extractors are not the same and require some fitting. HTH Link to comment Share on other sites More sharing options...

hatrick Posted October 19, 2020 Report Share Posted October 19, 2020 So can you use an MP28 bolt in an MP18,I? Would be nice to get a 28 bolt for shooting and not risk damaging the original bolt. Link to comment Share on other sites More sharing options...
Rekraps Posted July 9, 2021 Report Share Posted July 9, 2021 The MP 28 bolts will not work. They look almost identical, but are not. Nor is the extractor. I speak from experience as I own an original MP 18.1. Not wanting to ruin the original bolt (BTW, both bolt and extractor are serialized) I sent the material to Jason at Indianapolis Ordnance and he reversed engineered a bolt and extractor for me. Since my MP 18.1 is the later stick mag version, he also modified the bolt/mag interface to accept modified STEN mags. So the modified bolt works with both modified STEN and original MP 18.1 mags, while the original bolt only works with original mags. Link to comment Share on other sites More sharing options...
