Classic Army metal body M4

[THe_Silencer]

I was thinking of getting me an M4 from classic army because their metal bodies are quite sexy and and don't have those annoying laser engravings (the newer models anyways). At first I thought the only way of getting an M4 with the newer bodies was to splurge on the blowback models. I recently found out that they make a sportline model with a full metal receiver for much cheaper, which fits right up my alley. just wondering, does the cheaper sportline model have the same quality externals as the higher end blowback models? I can care less about the blowback gimmick or the quality of the internals but i really like features like a working bolt catch. This pretty much boils down to the sportline model having a functioning bolt catch. If it doesn't can working bolt catches be added on later?

I have one of the new model prolines, the regular ol' m15 series does not come with the blowback feature, however they do have a functioning bolt catch.

Several of my teammates have the sportline models; and the body is not nearly as good quality as teh proline. Not worth the 150$ saved. CA released the sportline series to compete with the cheap clones on the market. The sportlines also do not have a functioning bolt catch, and the charging handle doesn't even open the dust cover.

If you want a quality gun, go with a proline m15a4.
