Crooked FSB. Send back?

So I’ve got this rifle that has a slightly canted front sight block. While I don’t shoot past 200, and it’s still good enough for that, it bugs the everliving hell out of me. It also takes a pretty good bit of adjustment to get it zeroed.

Is this worth sending back to the manufacturer?

Also, when it’s canted like this, as far as I can tell it was drilled improperly at the factory and isn’t anything that can be fixed easily.
(If at all)

Should I just get over it or try and send it back? Am I making a mountain out of a molehill? It works for the ranges I shoot it at but it’s still not right.

Send it back if it bugs you.

Is it just me or have canted FSB been a huge quality control issue lately?

Personally I’d send it back if it bothers you…and obviously it does. You know what to do! :slight_smile:

a story told to me by an old time gunsmith who done a lot of work on U.S. and foreign military weapons, a guy brought in an old SP-1 and told the GS it shoots too far left, the GS looked at it and, “said that’s an easy fix, your front sight is canted…, i’ll be right back”, he went to the back of the shop which is out of sight of customers, he clamped the barrel in a brass barrel vice and whacked it with a rawhide mallet a few times till it was lined up, then he picked up his big steel mall and whacked his anvil a few times, then walked back out front with the upper in one hand and the mall in the other, and said, “there, that’ll fix’er, no charge”, the guy was about to faint.

soooo, send it back or whack the FSB to align it, your call !!

who’s the maufacturer? does the barrel shoot well otherwise? if it’s a great shooter, i’d think twice about sending it back.

i had an LMT that shot great but the FSB was canted. i just used it as an excuse to change to a shaved FSB and a longer larue handguard.

+1 If it shoots good, leave it be. I have a factory Colt M16A2 take-off that shoots like a dream but took more windage than that; it’s my favorite upper.

If you paid good money for it there is an expectation that you get what you paid for. Settling for inferior crap is how we end up dealing with Bushamsters, DPMS, etc…If I company is going to sell a product and make claims the only way to hold them to it is to make them fix or repair the item. This will hit them in the pocket book and maybe they will realize that it is cheaper to do it right the first time.

What if you bought a pistol from a local gunshop and you paid the “gunsmith” money for a set of night sights and installation and they were crooked? Would you just let it go because you are “close enough” when you shoot? The rifle can’t really be a “good shooter” can it if the FSB is crooked?

Send it back, and make them do it right.

The “windage” on a battle rifle’s iron sights is not for “the wind” (unless you are at Camp Perry). The adjustment is there to get your zero.

Mil-spec is approx 21 clicks on an 600m sight, left or right
More info here, see last few posts.

It seems that way. It started with the FSBs for AKs from certain companies and appears to be creeping into the AR side of the house. Maybe do to the high demand and the upcoming election, “some” manufacturers are increasing production and skimping on QC.:mad:

If it’ll shoot straight to 200, then it’ll shoot straight past that. However, I can’t see your pics. If you have to dial it very far off of mechanical zero, I’d have them make it right.

All to often we “settle” - I think we’ve gotten soft generally. I don’t care who made that upper, if it’s not right - it’s not right. Building uppers is not rocket science, (I’m not saying mass production is easy - just not rocket science). To let something like that get past QC - however slight it may be - is totally unacceptable.

I’d say, hold the manufacturer accountable with a letter saying that you have discussed this problem on different forums without using their name, and everyone agrees that its a QC problem. Maybe that will wake them up. If no or slow response, post their name so others can avoid them.

The FSB does not look canted to me and the Troy rear doesn’t look to far over to me (as the military allows for 21 clicks in either direction).

When reinstalling a FSB does it automatically go back into the exact same position or do you have to some how line it up perfectly again?

No, not always.

Really?

I thought that the pins holding it wouldn’t really let it wander one way or the other.

You get it close, but might have to give it a few whacks to get in the correct position.

Well hell’s bells, I wish someone had told me about that when I was reassembling the damn thing…

If you would have asked, I would have told you. :wink:

Generally speaking, most mis-alignment is becuase the pins were not installed back to their orig. position. If they are and are and the FSB is still off, you take a rubber mallet and smack the FSB till it is back in position.
