Chipley Custom Machine Series 6 Delrin Back Block Reviews
This is a CCM Series 6 Back Block and can replace the aluminium one that comes with the marker.It will also fit othe 2K style autococker bodies.It will not match the body design though. As always, CCM products carry a LifeTime Workmanship Warranty.
The Chipley Custom Machine Series 6 Delrin Back Block is newer, so it should be commonly available, both new and used.
owned FBM Qblock, compared ccm series 5 delrin, owned, orracle stock, owned 2004 prostockBlack magic (old style)as on outcast nightkast and 2k3's , owned some unknown screw in bolt/block combo, owned AIM brand Back Brick...
Orracle with belsales ram and qev's, E2 (and 420 trigger mod sometimes for messing around) slik bolt (I love this), ccm aluminum pump arm, etc.
I think I own 13 or 14 cockers most of which are pretty much maxed out, so that pretty much covers it.
Light, tight threads, looks good w/ my body.
Lack of a pre-drilled hole for rex dialer and top pin holes.
So far this is by far the best backblock I have used. I have seen several delrin backblocks and most are comparable. the best was some custom job which was blocky but light and already had holes for both top and side pins.
I like this one, because it has just enough material to be strong and enough threads. I think It will prove to be more durable than the slik products mini block, which might weigh a tad less. It looks much better than the series 5 ccm delrin block. It nearly matches my stock orracle block,Look at the first few pictures above can see for yourself.
I also really like that the threads are really nice and snug and tapped in far enough. many wgp blocks are tapped with worn taps at the factory which makes them loose and sloppy
on the pump arm which makes them rattle around and wear out the threads, it also tends to make the pump arm want to rotate, which can lead to the backblock hitting the body. these are good and snug. (I mostly bought this because my stock orracle block wore from slop and eventually all the threads were gone, so I put on this and an aluminum arm. way nicer. (I think my gun has had hundreds of thousands of cycles on it, mostly dry firing.)
I use this with a slik bolt and aluminum arm. my total cocking mass is negligible. I have less felt recoil than pretty much anything and that is on a cocker. I tested an etek ego a couple of weeks ago and that felt to me like it had more recoil... this is smooth fast and needs very little cocking pressure, which is what everyone with sense wants. A half block job wouldn't be very much lighter
For comparable products I would say several are close, but my choices would be in order as follows: 1. this 2. ccm series 5 3. slik (the first 3 are very close) 4. FBM q-block.
If you have any of those there is no reason to change, particularly if like me one of your guns has a q-block annoed to match., If you are building a gun there is no reason to buy anything heavier. don't think of aluminum as stronger, because it is also slamming more weight around which is hard on components.
Other than some custom jobs this is easily the best I have seen or used. It is well made good looking, strong and LIGHT
