    Spikes/AimSurplus CHF upper - Has anyone shot this yet?

    First off - I DON'T WANT THIS THREAD CLOSED DUE TO POINTLESS DISCUSSIONS OF DICKS, THE "TDP", OR WHETHER THEY HAVE A RIGHT TO STENCIL "FN" ON THEIR BARRELS. OK???

    I'm just interested in replies from anyone who has already gotten one and/or shot it...

    I'm pretty leery of their claim that it is capable of 1/2" groups depending on ammo, optics, shooter. -- if you have shot one, can you give us your results to include choice of ammo, conditions, etc.?

    also, can you give specifics on weight, barrel diameter before and after the gas block? is this a lightweight? more like gov't weight???

    finally, I WOULD like discussion on the perceived/actual benefits of a NiBoron coated BCG.

    please try to keep this a factual discussion. Spikes seems to get a lot of emotional discussion on both sides and I'm not looking for opinions, anecdotes, or innuendo.

    if you have data or experience, please add it. opinions, keep to yourself...

    I shot mine for the first time yesterday. It was only basic function testing, nothing more. The upper worked perfectly with 10 rounds of PMC 55gr FMJ and 5 rds of PMC X-Tac (M855). The lower used was a build of mine - the only relevant detail is that I used a sprinco blue carbine buffer spring and H buffer from G&R Tactical.

    Conditions were about 88 degrees and moderately humid (dewpoint around 68). Bright daylight, no rain. I did not attempt any accuracy testing. I just wanted to function test it and had a few spare minutes.

    I haven't mic'd the barrel OD but it appears to be roughly 0.680" or so. I'll try to measure it later. The felt weight of the upper is basically the same as a govt profile midlength 16", and a bit heavier than a BCM .625" lightweight midlength. I was surprised it didn't feel lighter.

    The NiB coated bolt and carrier is amazingly slick. It actually doesn't seem to hold oil, at least not SLIP2000 EWL. However it's so slick that it may not need to. I'll know more with more testing, of course. The little bit of fouling wiped off easily with a paper towel and it looked perfectly clean again. There is also a very noticeable layer of dry-lube film inside the upper - obviously most quality brands do that, but this seemed like a thicker than normal layer, which may be good, bad, or indifferent. Since function was 100% it's probably not too bad, at the worst.

    100% function after 15 rounds? A tad premature in my book.

    I think this is the opposite of the kind of post the OP was asking for.

    It's also a deliberate misquoting of what I said. My final paragraph statement using "100%" is specifically about the possibility that there is too much dry lube film in the receiver. My first paragraph is a factual description of what I did in testing. I do not claim 100% in the first paragraph, although it would be technically correct if I had. Nowhere in my review is a statement along the lines of "this is the most wonderfulest reliable upper ever, ST RULEZ!" which is what you seem to be implying with your misquote and reply. Anyone who belongs on m4c.net would be aware that 15 rounds doesn't mean much about long term reliability. However, the OP asked several specific questions and I have firsthand relevant knowledge, so I thought it nice to reply to his questions.

    I suppose "function testing" can mean various different things, but to me in this context it means "should I sight this in and start using it, or do I need to return it for repair/replacement?" I have a private berm on my property, but my formal range is a club that's 35 miles way, so I like to know if something is basically working before I load it in the car for a trip to the formal range.

    So, how is your ST-CHF upper working for you?

    I think you are reading too much into what I posted. I am actually very interested how these uppers do. I am not a ST detractor or fanboy (I am definitely not hoping they fail to prove some sort of grudge or something as you seem to imply). Sounds like I misinterpreted what you meant in your post, too.

    As for deliberately misquoting you, I am sorry you feel that way. That was not my intention and I don't believe I did. I merely connected two statements about the exact same subject to highlight what I was talking about. Your entire post is immediately above my post. I think you are ascribing intent to my post that wasn't there.

    Apologies for the derail.

    thaks for keeping it civil. I'm really interested in the accuracy potential of this barrel.

    advert copy claims it has 1/2 MOA potential. Tom from Spikes said that this is what he was told by FN rep. I find this hard to believe but even if it was twice that, it would still be interesting.

    I'm hoping someone can come back with good accuracy testing using a magnified optic and good ammo like a 69 or 77gr. match...

    Shot mine Saturday.

    Shot a little over 300 rounds, mostly XM193F with a couple mags of 75gr Prvi. I dialed.it in tight at 50, then made the adjustments at 100. At 50 it was a one hole group, at 100 I was shooting about 2.5" with the 193, and around 1.5 with the Prvi. I have a RRA NM trigger and was using a TA31F (red chevron) . Is the upper more capable ? Probably, .5 MOA ? I don't know, and probably never will, not that type of shooter.

    As far as the BCG, it did wipe off easily, but I only shot ~ 300 rounds. I used mobile 1 as lube before I went. There really wasn't any difference in that BCG and my BCM carbine I shot. Maybe with a higher round count session the benefits would have been apparent.

    If I get a chance go get into the gun room tonight I'll measure the barrel, I was wondering the same thing, just keep forgetting to measure it. Weight wise it feels ( nothing scientific ) like my 14.5 " gun with standard handguards.

    4.2 LBS was quoted as the upper weight as delivered. I'd measure but I don't have a scale of any sort.

    thanks for the review... 1.5" at 100 yards with one kind of ammo is encouraging. given the right ammo/optic/conditions, getting it down to 1" or thereabouts does not seem out of the realm of possibility.

    I'm really interested in the maximum accuracy potential of this barrel in the best case scenario. I realize it's not ever going to compete with the SPR's of the world but with good-enough accuracy, it could make a very decent Recce with a 1-4 scope...

    that is very reasonable for a CL barrel...
