    Hello,
    I'm in the middle of a project and i need alittle help with some fine tuning. I have transformed a ICS SIG 551 into my DMR. Its got a few upgrades:

    m135 Spring

    Poly carp Piston with all Metal teeth

    Matrix Prometheus Type Steel Perfect Sniper 6.03mm Airsoft AEG Tight Bore Inner Barrel (469mm)

    Angel Custom "Sniper" Airsoft AEG Hopup Bucking w/ V-Shape Teeth Technology - (Hard / 70°)

    Its defiantly got the range I'm looking for; however, beyond a 150 my bb's seem to fly left with every fourth or fifth bb staying on target. I'm shooting .30 and i'm looking at going to an even heavier bb or a new bucking. I was thinking about trying the reaps from evike or a systema. Any advice?

    You might want to try Rhop. What FPS are you getting? Have you shimmed and corrected AOE? Is the motor still stock?

    I'm getting 450 fps and i get a fairly good grouping with my fps.

    Honestly I don't work on my guns myself, was never very good at that sort of thing so I have not changed the AOE and I can only trust our local tech (I believe you know Noober) did a decent job with the shims.

    Because I'm not very good with machining things I haven't tried a r hop

    The Motor is still stock, It being an ICS it doesn't have to much problem with the 135 spring.

    Of you don't want Rhops grab a Systema bucking.
