hey ASC people, i'd like to present my two project GBBRs. both rifles built from scratch.
First, a franken-sniper rifle:
Internal:
- G&P hammer, trigger, sear, hammer stop, reinforced spring/pin set
- G&P barrel extension, Prime hop-up (AEG inner)
- Prometheus 6.03mm inner barrel (PSG1 length)
- WA bolt (oem) / RA-tech plastic nozzle with NPAS
External: (from front to rear)
- combination of Huang's Bushmaster sniper set (outer barrel/gas block) & SPR frontset (handguard/rails)
- typical bi-pod
- G&P M4 metal receiver
- G&P sniper grip, trigger guard (Knight's)
- G&P bolt stop, selector, mag catch
- 3-9x red/green scopes (oem) with riser
- (RS) Magpul PRS stock / A2 buffer tube
Next, my MAGPUL-UBR type M4:
Internal:
- Prime lower receiver parts kit
- Prime barrel extension, Prime hop-up (WA inner)
- PDI 6.01mm inner barrel (CQB-R length)
- Prime aluminum bolt / RA-tech plastic nozzle with NPAS
External: (from front to rear)
-
King Arms OPS Model 3rd MBS Silencer (Jugglez)
- Hurricane HK gas block (modified to fit inside CASV)
- Magpul MBUS sight (front/rear)

- King Arms CASV handguards
(modification on front to incorporate gas block / and modification on rear to accomodate rear MBUS sight)


- Prime MAGPUL metal receiver
- MOE Magpul grip
- ACOG (oem)




- Magpul UBR stock (chinese clone)


both rifles together:



not in any of these pictures, i also have an INOKATSU M4 (currently dis-assembled); which happens to be the first one i ever had, and was the basis for building these project rifles i now have. i intend to re-build the INOKATSU should the HK416 upper & front set come out sometime next year.
as you noticed, i went postal on applying crayons to highlight all the trademarks i could find. luckily, i can always remove these crayon markings anytime i want to. the PMAG on my M4 is just there for show. i'm hoping that a PMAGs for GBBRs will be out on the market as well as a VN style magazine.
Thanks for looking.
