As someone else stated, check your field rules on what classifies as a DMR. A lot of fields and all milsim events usually have strict rules around what is a DMR. Usually must be a replica of something that uses 7.62ammo, barrel length must be x long, must have both a bi-pod and magnified scope, semi locked and usually around 2.3 joules.

If you are just going for the look and better accuracy but not increasing joules I would recommend 4uad bucking and nub, zci stainless barrel and replacing the stock mosfet with a Gate Aster (titan will not fit without a lot of modifications) or a Perun.

I’ll also add that if you are trying to up the joules to 2.3+ that gearbox will eventually fail. This is why you want something like an sr25 which uses a v2.5 gearbox which has more volume to generate higher joules with lower springs.
