WINGS Borsighter Kit Precision Firearm Bore Sighter 16 Piece Arbor Set(Shotgun Adjustable Arbor Included).177 cal to .50 cal;3 arbor sets .177 .22.25

Does not work on full barrel moderator rifles

Very poor item Set too low. Even for my low mounts tried it on my BSA isu. You and on my ar 15 Did not work on either.

Works well only thing I find is it sits loose in the barrel.overcome this with a little masking tap round the columater and barrell

Very good but due to picture on ad I assumed wrongly that it came with more barrel rods than the 3 it came with wasn’t really happy about that

This is a BSA collimator. The grid lines where not vertical or parallel it was an x hair rather than a cross hair, took ages to line it up vertically using a plumb line and spirit level. Kinda defeating the whole purpose of buying the product in the first place.It only come with 3 arbors which are not sprung loaded overall pretty disappointed

Just as it looked in the picture. Arrived on time. Kit within all seems good quality. Case is plastic - nice and sturdy (no doubt will get brittle and snap where two halves meet over time). Already sighted in three rifles (.308, .17 hmr and .223) with it putting shots on the paper (within 10”) at 100 yd’s. Couldn’t have asked for anything better.

It's ok using it once or twice. But after that the spring bends down into the slit in the shaft and doesn't come back out. So, it's not holding the end adaptor for setting the gun tight anymore, so it's impossible to set the gun right

The Copper 'Spring' which is meant to secure it firmly inside the barrel, will fail and this item will spin around making it useless, this happened on my first use.A total disappointment and total robbery at the price. Avoid these THIEVES.
