Crosman 1701p tilted breech
« on: January 14, 2022, 07:25:10 PM »
I just got this new from Amazon.  As it is shown in the photo, the breech seems to be tilted to the left when I hold the stock straight.  Is it possible to adjust this myself?  Or it is quite out of tolerance in your opinion.  Thanks for the help!!

Could be your tube and its four 4-40 threads.

The top action can be easily removed without degassing, but do be careful and check the top and bottom transfer port seals when you put it back.

Thanks for the help! I'd like to hear some more feedback if it is normal and acceptable since I may not be able to return it once I work on it.

Are you sure that you are holding it straight?  It looks it from the picture, but it can be hard to tell.  It may just be the front sight mount shifted toward the right, slightly. 

If it is indeed tilted, then there is probably something wrong.  Maybe if both right side breech screws were loose and left side was tight?   Otherwise it is an issue.

It is not normal.

I am pretty sure that I hold it straight.  Here is another photo with a red dot sitting on it.

I tried some 7, 7.9, and 8.3 gr pellets, and the 7.9gr is doing the best.  Still within my limited testing distance in my garage (about 16 feet with rest), I got about 1/2" grouping, which is not impressive with this gun.  So I am leaning toward to return it back to Amazon.

Something sure looks like it's out of alignment. I know I would be curious enough to try to realign things.

I would be interested in knowing if you could loosen the left side breech screws about 1/2 turn and then tighten the right side screws to take up the slack. It just might realign like that. Might be worth a try.

Thanks for the idea.  I tried to loosen the two screws at the left side and then tighten down the right two (looking from back to front), but they are already bottomed out and cannot be further tightened. 

Considering the accuracy that is even worse than my 1377BR, it is going back.   :(

Now the question is if I should just get a replacement or a totally different gun.  I am looking for a solid low-maintenance 10m fun for paper target shooting.  Thanks!!

I wonder if the trigger frame could be aligned.

They are usually very accurate with the oem LW barrel.  Mine shoots JSBs very well.  For group testing, I do put on the crosman skeleton stock and a small scope.

Good call I think.
 With the alignment issues and accuracy comment, something is amiss.
 My 1701P is EXTREMELY accurate. Typically they are and would be perfect for informal 10M target shooting.
Amazon return policy is pretty painless, but if they balk Crosman will take care of you I am sure.
I don't need THERAPY.. I just need to shoot an AIRGUN.

Yes, very precise gun.

I have one that has a PROD tube and a 1720T breech; a carbine, actually.

I use mine at 25 yards.

Agree with Bill ...am open to the idea that the grip frame is angled to the air tube being a possibility.

Either way, as a new buy,  sending it back for exchange would be a good option.

---------
Took the time to see how far I could make a grip frame lean but still have the screws enter their threaded holes. Pettey far...more than your picture shows. Trigger still worked as designed.

All it would take would be a burr/flashing on that molded grip frame and the screws would tighten down firmly but leave a leaning grip frame.

Thanks a lot for all the help and comments.  "Very accurate" is what I always hear about 1701p, and that is the very reason why I try to get one.  Amazon has "no question ask" return policy for this gun and also lower price than Crosman direct.  Hopefully the quality of that gun coming from Amazon and Crosman direct will be the same.  Mine was arrived in two days, which makes me think the gun is already in Amazon warehouse.  And I hope it is not a return of anything fishy.   Maybe next time I'll directly order from Crosman.

Croman now sells them for 20% more.

Last month, it was around $411.

Yes, I saw that.  That was why I ended up with Amazon.  Maybe wait for the next round of discount.   :(

After spending more time with this 1701p, I was happily surprised that it shoots better and better.  Now even with 7gr RWS Basic, I got very nice grouping with support.  I honestly don't know why.  Maybe the gun needs some barrel cleaning, which I did not do, and gets better after some pellets going through it?   I also fine-tuned the trigger so that even my two-handed freehand get a lot better than my 1377 (due to its poorer trigger). 

As for the tilted breech (or more likely the tilted trigger/grip frame), it seems that the two screws mounting the frame to the air cylinder are tapped off-angle so that the trigger/grip frame is tilted with a slight angle. It really does not hinder any shooting since our hand easily correct for it. But I am curious that you have seen such mis-alignment in air guns??

I magnified your 2nd photo and can see the screw is not flush with trigger frame.   The front screw is threaded into the air tube while the rear one pictured is threaded in the end cap.   More likely they are cross threaded.  Still reason for return/exchange.

It would be interesting to see what was going on there. My money is on the frame misalignment rather than the breech.
