Crosman B272 4-Pc Intermount, 3/8" Dovetail

The scope base attached to the rifle very well, an excellent fit.

It would a good idea to incorporate the addition of a picatinny rail so it can be used with Weaver and Picatinny rings. Also make the scope mounts taller.

The bolt handle hits the scope if the scope is mounted past the bolt handle. Taller scope rings can solve this problem.

I needed a way to put a scope on a Morini 10 meter pistol to test pellets. I ordered this and the Crossman 459MT which is smaller. This is the one that fit over the carbon fiber barrel shroud which measures 14mm. The dovetail then measured 11 mm inside the groove.

One of the few ways to get a scope on a Benjamin 392.

I had to grind a little lip off the inside of the halves. When I would tighten the rings, it would lose the bases and they would slide lose on the barrel.

They work but you may have to fiddle with them a little.

The set I received had NO screws enclosed so I cant honestly say how good these work ...!!

Inspection of the package these come in to MAKE SURE they have screws included ..

I like that it seems to be made of solid steel, which is very nice due to durability and quality. It seems to fit quite well on my Pneumatic Benjamin Sheridan rifle

Make one long adapter rail, instead of two pieces, and one short one for Benjamin Sheridan Pistols.

Hold both sides of the sight adapter against the barrel on both sides before trying to screw them tightly together on your Benjamin Sheridan 1377, and other 13xx(1322) etc. rifles and pistols. Lastly, the screw that holds the adapters two pieces together is a flat head type screw, so you'll need a flat head screw driver or flat head tip to screw the two pieces together tightly on the barrel.

It is a perfect fit on my rifle

Decent, easy to use, fits early 80's Benjamin/Sheriden

The design is straightforward, nothing really to change

As a more mature airgunner, scope use makes it much more gratifying to shoot well, and it was a pleasant surprise how well the rifle these mounts were used on actually performed when not trying to see a fuzzy front sight and ghost of a rear sight.

One interesting aspect was when I removed the scope to use on another rifle and left the intermounts attached at the rear most part of the barrel, the intermounts provided an excellent "semi circle" peep sight that allows a full view of the bold front sight, that happened to be well regulated for accuracy at the shorter ranges. This adds an added dimension to this product. The stock open sights are too indistinct to use with older eyes, for the most part.

Perfect fit for my new Benjamin 397 pumper. I put them just fore and aft of the stock rear sight - no removal of rear sight necessary. Put 1" - 11mm (3/8") dovetail medium rings on my BSA 2x20 pistol scope and all works perfectly - holding zero after approx 500 rounds.

nothing

Do not over tighten these adapters' screws. Just snug them up to the barrel. They will stay put.

Easy to attach to my old Blue Streak Sheridan. Been wanting to do something about the original open sights, so this gave me the opportunity to add a scope.

Good price

Part is not built strong enough with screws that are too small as well as threads that are too fine and easily stripped. Part could be easily re-engineered with 8X32 screws with hex heads instead of flat heads. . Hard to understand why manufacturer has not done this.
