M2 had people bending barrels and remilling recievers to get a straight shooting barrel. Is the SBE2 different or do you need to send it to Redneck and have some magic installed?
I got an X-N model. Tried low recoil bird shot and 3dram bird shot and it ran fine out of the box no cleaning. Tried some 1410fps slugs and it one shot, round catching on the edge of frame and barrel not going into barrel. Have not tried since.
Best to email the match director for the local details and paperwork at least 4-5 months in advance. I remember attempting to go to Russia and was told at least 12 months wait for paperwork - match was in 3 months. Some countries are difficult with guns and foreigners - including the USA.
Always been soft. What issues do you introduce with hard?
I never seen a clear dot. Used a Core with 6 and Johnny Lim glare shield. Stay away from tube scopes - it gets worse.
