SOLD: 24" TJ barrel .30 cal conversion kit with .25 cal bolt
« on: February 28, 2017, 01:57:01 AM »
Selling my MARAUDER  24" TJ barrel .30 cal conversion kit with .25 cal bolt. This kit was special made by Roy at Mountain Air. It's not his normal 20" kit. Had to pay extra for every additional inch. Barrel has less than 300 rounds and very accurate.

Price reduced from $240 to $220 plus shipping PayPal family/friend/gift or add 3.5%

Message or Email me if you're interested or want pictures.

Do you know what the diameter on the barrel port is? And is this the .300 diameter barrel for pellets?

Thanks,
Chris

Yes, this barrel was design for pellets. The transfer port has been enlarged to .187". Roy at Mountain Air can probably tell you more about the twist rate and bore diameter.

It's pretty accurate and hard hitting from my experience. I tuned it to shoot in the 70-75 FPE using JSB 44.75g.

Hope that answers some of your questions.

.30 TJs are designed for the JSB pellets by Bob Sterne and Sean Pero. I believe they are .300 and .294 groove but could be wrong and they are 26" twist. Great barrels!
