BCM Blem for 6.5G build???

[tracker12]

Will this Receiver from BCM work for a 6.5G build.

BCM M4 Flat Top Upper Receiver with cosmetic blemishes. Most have scratches or scuffs.
The upper comes unassembled, but complete with BCM forward assist assembly and ejection port cover door assembly.
You must assemble it. (Assembly required) (all parts, but you will have to assemble together)
THESE ARE USED/DEMO UPPER RECEIVER ASSEMBLIES. All will have several nicks, scratches, and marks on exterior finish. NO HANDPICKING.
This receiver has the M4 feedramps machined in. This is to be used with barrels that include the M4 barrel extension.

Built to the correct Mil-Specs.
(Inside Diameter for barrel extension slightly undersized for a tighter fit to the barrel and a more accurate rifle. Please use a heat gun or hair dryer to warm up threaded bore of receiver if barrel extension is too tight.)



Features
• Precision machined to correct Mil-Specs from 7075 T6 Forgings
• NOT Assembled with forward assist, and ejection port cover
• Mil-Std 1913 Rail for mounting optics and accessories
• Machined for use with barrels that use an M4 barrel extension
• Laser etched T-markings for addressing the remounting of optics

It should work fine.

It will work fine. The one I used needed less lapping to true the receiver face than any other I've worked with.

Aside from the scratches and scuffs mentioned, as long as there is no other structural damage that would cause any issues, I don't see why it wouldn't. Where did you find it at?

Thanks. Thats directly from the BCM site.

I use BCM blem uppers on all my builds and prefer them.

When I lap them, their is barely any excess material, and the barrel to receiver fit is SNUG! I highly suggest either using a heat gun, or even putting your upper in an over for a short time to get it to swell so barrel insertion goes easy.

Believe me when I say if you don't, you will be swearing.

BCM does this tight fit on purpose for greater rigidity and potential accuracy.

Went ahead and bought one. Thanks for the advice Kilco. When you talk about lapping are you referring to the receiver face.

Correct, the receiver face. Last upper I did using an 18" AA barrel i didn't even bother lapping.
