Remington Ultimate and BP Xpress rifles
 

For those with either rifle, I would HIGHLY suggest you consider replacing your original breech plug, with the newly designed ASG breech plug. ASG first came out with the breech plug for the RUM, then followed with the new breech plug for the Ultimate Firearms Inc. rifles. Note: threads per inch are different between the RUM and UF rifles.

I had my BP Xpress breech plug exchanged and what a world of difference! No more head space problems. Modules hold the LRMP's and are easy to install and remove. ABSOLUTELY ZERO LEAKING of either the breech plug or the modules. This is a TRUE game changer for both of these rifles and with the new ASG breech plug you can shoot any propellant you'd like, including BH209! I've sent 20 or so rounds already and BH209 ignition is INSTANT.

This takes a rifle/s that have been like a mule and turned it into a thoroughbred!
