Well I bit the bullet and bought a Winchester Ranger 120 in 12 gauge 28" winchoke barrel.
Pros: it doesn't rattle like my old Mossberg, its lighter than a 870.
Cons: the dealer I bought it off.
I spoke to the dealer on the phone and asked all the relevant questions, he satisfied me that all was well just the usual wear.
When I took the barrel off the mag spring flew out, at quite good velocity I might add, not only did the spring fly out but a solid steel 3 shot reducer, weighing 6+ ounces. Why this was even in the mag tube beats me, the mag has been modified to fall in with UK law to only hold two shells. The length of pull is only 13 and 1/4 " due to a missing recoil pad, just a cheap piece of plastic on the butt.
Overall I like the gun, it works OK and hits what I aim at, I intended to fit a recoil pad as I could see on the dealers photo it hadn't got one, at least now I won't have to shorten the stock to fit one.
I find the ignorance of some gun dealers unbelievable...

I had to send a shotgun back a couple of weeks ago it was so far off the face I thought I was seeing things...

Whatever you do always give 100%........... unless you are donating blood.
