Rainer arms Ultra match 18 inch

[Travelingchild]

Changed out a 18 Faxon Gunners profile barrel, (didn't play well with Specwark suppressor ,5 inch groups at 100 yards) to a Ranier 18 inch rifle gas length Fluted Ultra Match 1 in 7.5 twist .https://i.imgur.com/yMJ6ts2.jpg

All shot suppressed off bench

Random ammo selection worst groups to best

Granted I'm still working on the 100 yard zero but trying to find factory ammo that it likes, then maybe try loading some 77 smk for it

Frakkin' nice! That Hornady load, 75gr BTHP, in 5.56, is the best performing factory load I've put through my BA 18 incher so far.

Whar chamber do you have in the Rainier barrel?

I have one of the older original Rainier arms ultra match 18" .223 wylde spr barrels based on the Shilen blanks with ratchet rifling and it is still an excellent sub-moa barrel. Great quality. Handloads with LC brass and 77gr noslers is fantastic.
