Just received my moded .25 cal Marauder from Travis over at ART and this thing is like a total different rifle now. Its now making just under 86fpe with 49gr slugs regulated to 2500psi with a 4500psi 500cc carbon bottle and his drop down/block adapter. The moderator is from bwaltonpcp.net and it works amazing too. Its buttery smooth to cock now. Im super impressed with his work and service from comunnication to the delivery of the rifle. Recommend him to anybody that needs work done on their rifles. Thanx again Travis. Keep up the good work
