Hector put a gas ram and tested barrel in my LOA. Wow! He also adjusted the incredible trigger. It's better then t o 6 and definitely a peer of Record triggers. Sadly, my Diana 340 gas ram took a gas leak poop. Parts are not at retailers. Rifle is discontinued after a very short promotion. I really like the 340 stock shape. It's the best IMO. I also got a hand picked curly walnut stock selected by Lauren Parson at Airguns of Arizona. Now I gotta send the 340 to somebody for repairs. Shipping is costly nowadays.
