18" SPR build

[CM1021]

Well I finally finished up my SPR build. I've been on this project for about 3 months and my barrel finally came in today so she got assembled. Haven't had a chance to take it to the range yet but will definately this weekend. Also am still pondering optics as I would like to see how she shoots out to 500-600 yards. other than that she just needs a Harris pod and she will be all finished up! Parts list and of course pic!

she should be a shooter, what is a 223 match chamber?

so i take it no 5.56? i normally do not shoot 5.56 myself unless it is long distance at 600 or better. then its 5,56 77 OTM

[CM1021]

It's a .223 chamber. It's tighter than a 5.56 and this gun will only see black hills .223 or handloads so that's why I went with the match. I have been told I could still feed it some 5.56 as long as it doesn't have a steady diet of it.

You were told wrong, if your rifle has a .223 chamber only feed it .223 cartridges.

A .223 chamber will take a 5.56.

Is it smart? No, not necessarily.

[CM1021]

Well it's not going to see it anyways so I'm not going to argue with you but the gentleman I was told this by KNOWS what he's talking about. If the SHTF and all I had was 5.56...it would get fed 5.56

You could feed it 5.56 and probably be ok.......until it's not ok. You run higher pressures and could have a higher probability of malfunctions. RichardR is wrong.

It's doable, just not smart....or necessary. You're on the right track though.
