I often get many Nelson based pump parts available to me, so i will be posting them all here as ongoing. After just a quick look, this is what I found, I know it's not a lot, but more is coming:
Everything is always OBO and I take trades, just offer, but paintball items only. Buyer to pay actual shipping (no more than 4-6 for small parts)
Trracer Power tubes - 2 are definitely trracer, one is different. $10 each or $20 for all 3.
Trracer Valve nut - $10 or $5 if bought with above power tubes.
Nelson #4 Powertube - $10.
USI Muzzle brakes - Mount onto 1 inch OD barrels (I think). 1 has a front bead sight but is missing the set screw. The other has both set screws. $15 each or $25 for both.
Splatmaster (I think) Barrel - brass. in good condition for it's age. $15, I dunno, just offer.
Phantom Back Bottle Adapter - Long Style - has scratch, please be aware, look at pics
Phantom Delrin Pump Handle - slight wear
"New Hammer" Trigger Frame for Kingman Hammer - all plastic, grip is hollow, auto-trigger, working safety.
Bottomline Adapter for LoneStar Grips (I KNOW these work in trracers, mavericks and hornets) - one is just adapter ($10), one has braided swivel line with back bottle plug ($20)
Nelspot 007 Frame w/ Shoulder Stock - Please see pics. Second gen with keyhole style milling for newer pierce pin. it's a little dirty and needs some love, but is sold, with working internals and working safety. Only right side grip panel. $30 plus shipping (which will be a bit more because of stock size)
I have a monster bag full of springs. I believe most are cocker springs.
