It does need to be pretty precise to fit.B est if the manufacturer can do it or give him the reading of your barrel at the point the bushing will sit on your barrel.
Having said that some guys dont use the rear bushing and have had no alignment issues to date but I guess if a manufacturer builds it with one then you might not be covered if you do get misaligned and have a strike.
Im sure there are a few guys on here not using the bushing.
Give DPT an email he replys quickly and has been great to deal with.
Lead delivery technician, Bulk orders welcome!!
Had a discussion with a suppressor manufacturer yesterday on fitting one to my 6.5 x 55. Said I'd want an over barrel to reduce the forward extension. His view was only about the first 40 mm of the over barrel works to help the noise reduction, the suppression is done by everything forward? Thoughts, experience? Appreciated
Boom, cough,cough,cough

@rambo-6mmrem take off the plastic rear bush, screw the suppressor on tight, now do you have a vernier caliper or a micrometer?......if yes, measure the tapered barrel as close to the end of the suppressor as possible....
this will be the drill size diameter you will need, then screw plastic bush back in suppressor, now you will need a lathe with a 3-jaw chuck, wrap thin cardboard around your suppressor (dont overlap) its just for protection so you dont scratch it....
put correct diameter drill in the tail-stock and slowly drill out the excess material from the bush, chuck speed around 600 RPM should suffice, go slow on break through as sometime the drill will grab.....de-burr both edges.....done!
ive got two DPT suppressors, 3 bushes, did mine this way easy-peasy!!!!!
While I might not be as good as I once was, Im as good once as I ever was!

@Maca49 aka Oscar the Grouch. Getting one off your mate or buying in the marketplace ?
Don't matter you need over barrel for that gun any way and dont shorten it any more than you really have to.
That gun type and caliber best performance if not too short. The guns too nice to mongrelise ... That guns pretty short already in factory form IIRC. ?

Although that can work if you drill the bush over size. You are best to clock the suppressor up in a four jaw chuck and then bore the bush (not drill) so everything is perfectly concentric. We normally machine the bush slightly oversize by 0.05mm. If everything is not perfectly concentric and the bush is tight then the suppressor can load up one side of the barrel and cause accuracy issues.
@DPT if i sent you the messurements from 105mm back from muzzle? are you able to do the job and if so how much do you charge
i agree with you @Maca49 the noice reduction its the same however there are other advantages to over barrel
1. ballence the suppressor isn't hanging off the end and there fore nose heavy. an overbarrel puts some waight further back to counter the noze heavyness a bit you may think that somethig as light as a dpt wouldn't matter but you do know its there wants to pull the muzzle down
2.more sturdy with a muzzle can the hole can is hanging off the muzzle thread thats alot of leaverage to damage something if you drop the gun... with an overbarrel you have 2 support points the muzzle thread and the rear bushing
3. slightly less extention beond the muzzle
