Moderator Adapter for Steyr’s LP50

I’ve been trying to find a part number for the new Steyr LP50 Action barrels (without ports) for some time. Emailed Steyr directly several times to different people with no response. Tried going through Krale, who contacted Steyr, who sent Krale a copy of the “latest” exploded parts diagram and parts list. Still has the same part number as the old barrel with ports. Very frustrating.

Contacted Sport Shooting Depot, a new Steyr distributor here in the US (Mich). He contacted Steyr who replied they could not sell him any parts because the LP50 Action was part of the “Adventure Line” and he was a “Match Line” dealer. Steyr told him that Edgun West was the “Adventure Line” dealer in the US. Problem with Edgun West is they want to sell complete pistols, and will not stock or order individual parts.

@Helmet: Could you possibly use your contacts to find the part numbers for both compact and standard barrels for the LP50 Action pistols?

A bit disappointing that they don't respond to direct contact, but it may indicate that the associated user manual and parts list are not ready yet. I have always gotten a response back when I have contacted them directly in the past. I will try through a couple of acquaintances.

Then my "rubber cord" approach is a little improved. From the factory the compensator holes are drilled to ø3mm a bit into the barrel wall, then the last ~0.5mm is drilled to ø2mm. That means there's a little shoulder at the bottom of the comp holes. Take a 3mm rubber cord and cut off three pieces of 4mm length. I used a ø13x3 o-ring. Put those ø3x4mm rubber pieces into each comp hole before you lay the cut-in-half ø6x13 rubber pieces across on top. Then fasten the rubber pieces with the Steyr Weaver rail or an other suitable device.

Tested it now and the only sound coming from the LP50 is the ping from the valve.

NB! There is some force working against the set screw that holds these parts in place, so be sure the device holding this together can withstand the force.
If we ignore the fact that the pressure drops slightly as the pellet passes through the barrel, then the pressure that works against the screw that holds the parts in place is about 50 N for the standard LP50 and about 64 N for the RF version. For the HP version the force is about 100 N. These are not high numbers, but anyway, be sure what you use is strong enough.

Have to say the Steyr LP 50 RF (with some woodwork) covers a lot of my needs when it comes to plinking and target shooting.
Yes, there is a noticeable bark to it, but the silencer takes care of that.
The content in this gun case gives you the possibility to change between different pistol/rifle stocks, pistol/rifle scopes, a red dot, or simply the use of iron sights.
