[ctcs]

Quarter Circle 10 AR15 Glock Small Frame Lower Receiver

• QC10 Stripped Glock Small Frame Lower Receiver with proprietary parts
• Engineered for 9x19mm or .40 S&W Glock magazines
• Milled billet 7075-T6 Aluminum
• Type III Hard Coat Anodizing
• Made For the AR Platform- Not Modified
• Accepts mil-spec receiver extension (buffer tube)
• 11.5 oz stripped weight

For proper function with calibers other than 9MM, QC10 recommends pairing the GSF lower with an enlarged ejection-port upper, like the QC10 Pistol MUR.

This lower is a stripped lower and will require a Mil-Spec Lower Parts Kit to complete. All proprietary parts will be included (last round bolt hold open, magazine catch, ejector etc)

Requires a Glock Style Bolt for use with Glock magazines (will NOT work with bolts designed for use with Colt SMG magazines)

Any interest in bringing in the Colt SMG lowers and bolts?

[chicu1981]

how much for the whole thing? Also is there a pistol version so that we can have 10 round mags?

Glocks use pistol mags

[Waynetheman]

Lol are there non pistol glocks?

Lol!!

I just want to make sure I understand a few things correctly.

The lower uses "standard" 5.56 LPK, and it needs a dedicated BGC.

So to convert an existing Colt 9mm system, it needs a the Lower, a new LPK and a glock mag specific BGC, right?

Yes this is correct. The Glock mag specific BCG is required for the bolt hold open to work with Glock mags.

These are awesome little guns,one thing about the BHO,it's not all that reliable with factory glock mags,the ETS mags work great though
