A new larger eye bell diameter batch of 20 some bloke Collet Chuck DSA’s is now available with some revisions that upgrade these originals: http://nightvisionforumuk.com/viewtopic ... 05#p100805
They are now made as default to fit larger 45mm diameter down to 43mm plain/uncluttered eye bells with no illuminated retical module or silly ridges like the MTC's have. Now revised with two split collars to fit eye bells down to 41mm - (not shown in photo)
Raising the eye bell capacity has resulted in the need for a larger diameter screw cap - which is now likely to foul centre fire bolt retraction unless high scope mounts are used. Seen here on my REM 700.
They have a 50% coarser clamping thread and are made from Acetal which is not hydroscopic so will not 'grow loose' at the rear end like the original nylon one's. Acetal is cleaner to machine so the thread is better defined and smoother.

The user decides his camera cable exit location and drills the hole for it as required.
Price for the new spec raises £5 to £40 - but is supplied with a standard ribbed Floplas end cap fitting which is a nice tight friction fit into the rear section of the adaptor.
An optional upgrade is a smooth end cap which has the ribs machined off at £5.
RMSD will be £7.
